Geochemical and Geological Characterization of Clay in the Eastern Part of Hawal Massif Around Mubi and Environs, Northeastern Nigeria

The geochemical and geological characterization of clay is an important approach to determining the quality and productivity of clay for industrial use. This paper is aimed at providing detailed geochemistry, distribution, and utilization of clay from the eastern part of Hawal massif. The field study revealed that clay occurs in Bagira, Vimtim, Didif, Bulamary, Ngavahi, Dou-Gada, Madanya, TudunWada, Moda, and Kwabapale. The clays are residual deposits formed by weathering of feldspars from the granitic rocks, the clay deposits are restricted to the basal parts of highly weathered granite. The depth to which the samples were collected ranged from 0.6-1 meter. The clay was analyzed using the Xray Fluorescence (XRF) machine. The average concentration of the major oxides shows that SiO2 is 38.7%, Al2O3 is 9.62%, Fe2O3 is 5.48%, TiO2 is 0.69% and CaO is 0.598% while MnO, ZrO2, ZnO, V2O5, CdO, Cr2O3, SnO2 and Sb2O5 all have lower than 0.07%. This result shows that the clay in the study area can serve as a good raw material for the manufacture of traditional ceramics, refractories, and structural clay products especially burnt bricks.

Meroitic building techniques: some observations from Abu Erteila (Sudan). Сonstruction materials and methods.

The article is devoted to the general tendencies in the architecture of the Meroit period (c. 3rd century BC – 4th century AD) of the Kingdom of Kush (c. 9th century BC – 4th century AD), local building materials and technologies that determined the distinctive appearance of Meroitic architecture. Construction activity under Natakamani and Amanitore rules covered almost the entire territory of the state. By the 1st century BC the Meroe district had significant resources and became a large centre of monumental architecture, around which cult complexes were built in the neighboring settlements, such as Hamadab, Awlib and Abu Erteila. This construction was achieved not only through stone mining, but also through applying advanced building methods, sophisticated brick-making techniques, and combined materials (mud brick and fired brick, iron and sandstone, wood and plaster), as the second part of the article describes the 1st century AD at Abu Erteila temple complex. The dimensional and proportional analysis and the description of the building materials and architectural elements used were applied to two small Meroitic temples (main one small ) found at Kom II in Abu Erteila. The analysis of the main temple's dimensions showed that its construction had taken the form of an Egyptian royal cubit (52.3sm). The preliminary excavations showed the proportions of 8:5, which had been recorded in the plans and facades of many other temples of the Meroitic period. The materials used for the construction of these two temples demonstrated the mixed technique of building used by the Meroites, when mud bricks were used for the main mass of the walls, fired bricks were used for the facing of the walls and the pylon, and moulded bricks of burnt red clay and sandstone were used for the architectural elements. Three types of foundations can be traced in the temple complex, which varied depending on the time of construction, height of the walls or specific features of the site soil. Methods to control swelling and cracking of the ground along the plastered surfaces with paintings close to the ground level are also documented. The various passageways in the two temples had thresholds of burnt bricks or dark sandstone, pilasters along the sides, and pillar stones for single or double doors, showing the well-developed construction in many temples of this historical period. Consequently, many of the surviving sandstone architectural details (columns, cornices, friezes, torus mouldings, water spouts, elements of relief decoration etc.) found inside and near the main temple, based on the unified style of various temples in the region, allowed to make an early general reconstruction of the temple.

Strength Assessment of Improved Adobe Brick Using Natural Stabilizers

Adobe or mud brick building technique is an ancient technique dating back at least to 8300 BC. The oldest continually inhabited structures in the world are made in adobe. Adobe brick have revealed many advantages such as low cost, simple construction, excellent thermal and acoustic properties. Dispute these advantages, adobe buildings experience many problems, like water effect and low brick strength, among others. The objective of this study was to assess the strength of adobe brick made from natural soils and stabilized using laterite, fine sand and fibrous grass. The study first checked the quality of all used materials components, and then with reference to the USCS, the classification and quality of those materials were determined. Afterwards, the controlling brick sample made of natural soil, and the stabilized brick made of natural soils with stabilizers were manufactured using the mix ratio of 50% natural soil, 30% of laterite, 15% of fine sand and 5% of fibrous grass. After the bricks curing, the compressive strength test was performed. It was observed that the adobe brick strength was improved from 1.04 N/mm2 to 2.128 N/mm2 after its stabilization. Further studies were recommended regarding the improvement of adobe bricks performance using other soils mixture content, or other types of stabilizers with target to achieve the strength of stabilized soil bricks with cement or even the strength of burnt bricks.

Kumbyz (furnace) found in the medieval city of Kyshkala

Long-term studies of the medieval city of Kyshkala revealed a mausoleum, madrasahs, simple burials and living quarters built of ceramic bricks and the remains of cult and memorial construction sites. A number of studies were also conducted to find out where so many bricks were burned, and consequently, in 2019 brick-burning kumbyz (furnace) was found in the eastern part of Shahristan in the medieval city of Kyshkala, dating back to the Golden Horde era, to the 13th and 14th centuries. Therefore, in the article, giving extensive definitions related to etimology (origin) of the word “kumbyz” for burning bricks, we will focus on the history of kumbyz of the medieval history of Kazakhstan, which had a direct impact on the prosperity of urban culture. The kumbyzes were found in the Chui region and such medieval cities as Aktobe, Sarayshyq, Zhaiyk, as well as in the medieval cities of middle and lower flows of Syr Darya. The article considers the history of discovering kumbyzes and the conducted archeological research, the first published results were supplemented with additional materials and a comparative chronological analysis

Block Laying Heights and Physiological Indices in Masonry Work

This study investigated the physiological response functions of the masons during masonry work using three standard sizes of construction block weights at varying working heights. The assessment involved a repeated job handling design approach. The participants in this study were 12 masons who had at least one year of experience in working with sandcrete blocks and burnt bricks. Each participant constructed 20-block walls, 7 courses high using 9 inches and 6 inches sandcrete blocks and 20-block wall, 11 courses high using burnt bricks. The physiological response data measured were heart rate, body temperature and blood pressures (systolic and diastolic) at each wall height constructed. The ergonomic investigation principle of the work factors affecting masonry work was hinged on known physiological indices (oxygen consumption and energy expenditure rate) to evaluate the degree of the effects of the task on masons. The result obtained showed that the masons experienced different levels of stresses at ground level to knee height, knee height to chest height and neck height while working with the 6 and 9 inches sandcrete blocks. The building construction using burnt bricks recorded varied results, as there were no differences in body temperature, heart rate and blood pressure throughout the wall height. This study concluded that the construction block weights have effect on the physiological response functions of the masons at varying working heights.

An Investigation into the Local Production Technology of Burnt Bricks in Nigeria

The acceptability of fundamental features of burnt clay bricks is a control course obtained during the production process. The applied knowledge and skills in production technology of burnt clay bricks were subjectively evaluated and quantified. Multi-method research approaches were adopted which included questionnaire instruments and experimental analysis. Assessing the source of knowledge and skill, the experience of labour and team capacity showed that most of the participants have been in the burnt brick production business for 6-10 years (37.3%) through the tutelage of their friends (72.9%) and participated in the groups of 4-5 people (25.4%). There was a deficiency in knowledge and skills needed for forming and firing stages for standard quality burnt clay brick but only effective in the extraction and preparation stage but deficient in shaping, drying, building the field kiln and firing the field kiln. The independent-sample t-test showed that the mean of the measured water absorption value of the locally produced burnt clay brick was statistically higher (mean ± SD = 29.51±0.58) than the minimum allowable standard water absorption value (mean ± SD = 20.00±0.0) significant at p = 0.00. A similar observation was made for compressive strength as the measured mean compressive strength value for the locally produced burnt clay brick was 3.98±0.30 N/mm² which was statistically higher than 3.5 N/mm². However, the dimensions of the burnt clay bricks were with the tolerance of approximately 5% for locally produced bricks. Considering the importance of good quality burnt clay bricks in construction local producers need a training.

Проблемные вопросы изучения золотоордынского города Мохши

Research objectives: To analyze the problematic issues of the chronology, periodization, historical development, and economic development of the administrative center of the northeastern ulus of the Golden Horde – the Mokhshi city (Narovchatsky settlement). Research materials: Data from archaeological excavations of the Narovchatsky settlement, numismatic collections of the Golden Horde coins, and previously published works on this issue which need a critical approach and the addition of supplementary details. Results and novelty of the research: The history of the existence of this city covers the period from the XII century to the beginning of the XV century. The main sources are materials from archaeological excavations, including numismatic collection of coins minted in the Mokhshi city. Urban development objects are represented by mausoleums, mosques, industrial sites, and residential buildings, information about which is supplemented by finds of jewelry, household items, and weapons. In the pre-Mongol period, a Mordovian settlement arose here and at the beginning of the 14th century, the ulus center was transferred from the city of Ukek to Mokhshi. From that point, the city experienced its most flourishing period when it became not only an administrative but also a trade and craft center. Copper and silver coins were minted in the city. Buildings made of burnt bricks were erected, a white-stone mosque likewise being built. The development of the production traditions of the local Mordovian population continued, influenced by Volga Bulgaria, and noted changes in the spiritual culture of the site can be associated with the spread of Islam. From the mid-1360s, the decline of both the city itself and its rural districts can be observed.

Utilization of Construction and Demolition Mix Waste in the Fired Brick Production: The Impact on Mechanical Properties.

The European Green Deal, which emphasizes zero-waste economies, and waste recycling in construction and building materials, has arisen due to significant worldwide needs for solid waste recovery and usage. This ambitious study focuses on recycling mixed construction and demolition (C&D) waste into burnt bricks and investigating the influence of firing temperature. While pursuing its objectives, this is dependent on raw material characterization and burnt-brick product quality assessment. The recycling of mixed C&D waste is explored by mixing the waste into two soil types (alluvial and laterite) in ratios ranging from 5% to 45% at three firing temperatures (700 °C, 850 °C and 900 °C). The utilization of mixed C&D waste in amounts of 10% at 700 °C and 25% at 850 °C and 900 °C fulfilled the Indian standard. Although a fire at 700 °C results in less optimal waste utilization, it is beneficial and recommended for reducing the carbon footprint and energy use. Additional mineralogical and microstructural analyzes are performed on the optimal fired samples. The study's findings are promising for sustainable resource usage, reducing carbon footprint, and reducing waste disposal volume. This research is a big step toward the Sustainable Development Goals of the United Nations and a circular economy.

Effect of Crushed Coconut Shell and Over Burnt Brick on the Mechanical Behaviour of Green Concrete as a Partial Replacement of Coarse Aggregate

Coarse aggregate (CA) is a major ingredient of the concrete, constituting around 60-75% of total concrete volume in a conventional mix design. The demand for CA is drastically growing, resulting in the diminishing of natural resources, and its extraction demands heavy machinery input, which triggers additional environmental issues. This research investigates the mechanical behavior of green concrete by partially substituting CA with wasted coconut shells (CS) and over-burnt bricks (OB). CS replaces at 5%, 10%, and 15% during the mix design, whereas OB substitutes at 20%, 25%, and 30%. Total 216 specimens were cast in the form of cubes, cylinders, and beams. It was observed that the workability and density of concrete decrease with increasing CS and OB. The compressive strength, split tensile strength, and flexural strength of the specimen decreased in both substitutes with the increasing amount of substituting materials when used individually. However, an increment is found in the mechanical behavior of green concrete when CS and OB were both used at 5% and 20% replacement, respectively. The study has multiple implications for casting eco-friendly or green concrete, such as the reuse of waste materials, reducing the carbon emissions obtained from the extraction of CA, and preserving the natural resources.

Treatment of Clay with Oil Palm Fibre Ash and Rice Husk Ash Mixture for Burnt Clay Bricks Production

The current study examines the use of oil palm fibre ash (OPFA) and rice husk ash (RHA) mixture in the treatment of A-6 Makurdi clay for burnt brick production. The results show that the compressive strength of 9.4 MN/m2 for burnt untreated brick increased to 10.86 MN/m2 for burnt 2%OPFA+2%RHA treated brick. The corresponding water absorption of 14.9% for the burnt untreated brick increased to 16.2% for burnt 2%OPFA+2%RHA treated brick. The strength value of 10.86 MN/m2 is greater than 10.3 MN/m^2 which is the minimum strength value for negligible weather (NW) conditions. The water absorption of 16.2% is less than 17%, 22% and ‘no limit’ which are the maximum values for severe weather (SW), moderate weather (MW) and NW respectively. Based on combined strength and water absorption criteria, burnt bricks production with 2%OPFA+2%RHA treated A-6 Makurdi clay is adequate for use as a load-bearing brick in wall areas of NW condition.

IMPACT OF BRICK KILNING ON THE ENVIRONMENT: A STUDY ON KHULNA REGION OF BANGLADESH

This study identifies the patterns of energy consumption in brickfields as well as their impacts on the environment. An attempt has been made to estimate the emission of pollutants from brickfields to assess the impacts of the pollutants on human health. Finally, an attempt has been made to find out a solution to sink the CO2 emitted by brickfields. Brickfields use coal, wood fuel, and crude oil mainly for burning bricks. Estimation reveals that in Khulna Region (KR) for the years 2003-2004, the coal requirement was 162 kton while the wood fuel required was 133 kton. Estimation also reveals that for KR the annual emission of the pollutants are about 738608 tons CO2, 94 tons of CH4, 13 tons of Nitrous Oxide (N2O), 1989 tons of NOx, 4264 tons of CO, 168 tons of Non-Methane Volatile Organic Carbon (NMVOC) and 15942 tons of SO2. Estimation also shows that, for the present level of CO2 emission in Bangladesh, annual afforestation requirement is about 1.4 x 109 m2. The predicted concentration at 200 m downwind of brickfields is 3000 μg/m3 for SO2 and 300 μg/m3 for NOx and PM-10 during winter, while for summer the concentration is 1000 μg/m3 and 125 μg/m3 respectively. From the high concentration of these pollutants people face some health problems. About 30% of the brickfield workers suffer from dizziness while 60% feel fatigue and 75% suffer from headache. Those working for many years feel fatigue more than the new comers, 55% and 3% respectively.

Mud and burnt Roman bricks from Romula

Sesquipedalian mud and burnt bricks (second to third century AD) were excavated from the Roman city of Romula located in the Lower Danube Region (Olt county, Romania). Along with local soils, bricks are investigated by petrographic analysis, X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT-IR), electron microscopy (SEM/EDX), X-ray microtomography (XRT), thermal analysis (DTA-TG), Mӧssbauer spectroscopy, magnetometry, colorimetry, and mechanical properties assessment. The results correlate well with each other, being useful for conservation/restoration purposes and as reference data for other ceramic materials. Remarkably, our analysis and comparison with literature data indicate possible control and wise optimization by the ancient brickmakers through the recipe, design (size, shape, and micro/macrostructure), and technology of the desired physical–chemical–mechanical properties. We discuss the Roman bricks as materials that can adapt to external factors, similar, to some extent, to modern “smart” or “intelligent” materials. These features can explain their outstanding durability to changes of weather/climate and mechanical load.

Performance Evaluation of Structural Lightweight Concrete Using Jhama Brick as a Partial Replacement of Coarse Aggregate

Through the ancient time structural lightweight concrete has been used successfully all over the world due to having its pleasant property of reducing dead load of multi-storied buildings which is very much important for high rising structures. This research represents the experimental works on the structural lightweight concrete to observe the cost and the physical properties using jhama brick (also known as over burnt brick) chips as partial replacement of coarse aggregate. For producing C-35 grade concrete, jhama brick chips was used for the partial replacement of coarse aggregate by 0%, 5%, 10%, 15%, 20%, 25%, and 30% weight of coarse aggregate. For this purpose, 21 sets of cylinders (100 mm x 200 mm) were prepared. Slump tests were carried out for each mix in the fresh state and 3, 7 and 28 days of compressive strength tests were also performed in the hardened state. The 28-days compressive strength of concrete with 0%, 5%, 10%, 15%, 20%, 25%, and 30% replacement of jhama brick chips were 37.12, 36.37, 34.23, 33.01, 30.89, 30.50, and 21.98 MPa respectively. The unit weight of concrete with 0%, 5%, 10%, 15%, 20%, 25%, and 30% replacement of jhama brick chips after 28-days curing were found 2409.3, 2379.2, 2286.9, 2230.2, 2197.0, 2104.1, and 2094.9 kg/m3 respectively. According to ASTM C 330, the compressive strength of concrete with jhama brick chips up to 25% of coarse aggregate fulfilled its requirements.

A Laboratory evaluation of Paper mill waste in manufacturing of Clay Bricks

India has one of the world's fastest expanding pulp and paper markets. With a growth rate of more than 10% per year in terms of per-capita growth, The pulp and paper industry requires a lot of capital investment, energy, and water. A paper mill produces 40 to 50 kg of dry sludge (70 percent primary sludge and 30 percent secondary sludge) when 1 tonne of paper is produced. Most of this sludge is now disposed of by land spreading and filling, both of which involve high disposal costs. Pulp and paper industry is one of the most polluted industries in the world in general and India in particular. India produces 10.11 million tons paper per annum which is 2.6% of world’s overall production quantity of paper. This study present using paper mill waste as a component in the manufacture of burnt bricks as a possible route to environmentally friendly construction. This research report details the findings of an experimental investigation into the production of eco-friendly, bricks using soil and paper mills. This research exhibits some increased compressive strength in mix of papermill waste.

Handling the Sludge When Using Polyaluminum Chloride as a Coagulant in the Potable Water Treatment Process

The sludge produced in the treatment process depends on the type of coagulant and other chemicals used and the suspended particles present in raw water. Discarding this sludge in the landfills poses pollution of both ground and surface water, disturbing the lives in the water and the water quality. The primary potable water provider in Sri Lanka is the National Water Supply and Drainage Board. It focuses on finding ways of disposal, sustainable practices, and possible applications of the water treatment sludge. This research aims to identify the aluminum level in the potable water treatment sludge of the Konduwattuvana water treatment plant in Ampara and to utilize that sludge as an alternative raw material in burnt clay brick manufacturing. The national standards and limitations of the sludge content and the standard brick manufacturing process were followed. To reach the aim, a sequence of tests was conducted, and the brick characteristics are subjected to test for different sludge ratios according to the Sri Lankan Standard of 36:1978 for burnt clay bricks. Experimental results show that the aluminum content in liquid sludge and sludge cake was found to be 231.6 mg.L-1 and 54.9 mg.L-1, respectively, which implies that the sludge contains aluminum. The optimum sludge ratio to produce burnt clay bricks was found to be 10% of the total weight of the brick.

Comparative Study of Solid and Hollow Laterite Soil Cement Press Brick for Different Proportion

Abstract: Brick is one of the important construction materials in the building. There are so many different types of bricks present in the market, like burnt brick which is the most common brick used in the construction industry. There are so many disadvantages of burnt brick like air pollution, wastage of material, not proper baking, etc. For this brick, laterite soil cement press brick is the best option and can be used effectively in future. In this project the solid and hollow brick of laterite soil cement press brick were formed by varying proportion of fly ash. The tests like compressive strength, water absorption and density were performed and compared for solid and hollow bricks with different proportion. The compressive strength test was performed on compressive testing machine. From this project, it was observed that by decreasing the fly ash content, compressive strength increases. Keywords: laterite soil cement press brick, compressive strength, Fly ash, water absorption

Assessing local perceptions of deforestation, forest restoration, and the role of agroecology for agroecosystem restoration in northern Malawi

AbstractDeforestation drives climate change and reinforces food insecurity in forest‐dependent communities. What drives deforestation varies by location and is shaped by livelihood systems. But how locals perceive restoration is crucial for developing restoration policies. Evidence suggests that applying sustainable farming strategies can potentially restore forests and sustain livelihoods. Applying a broad‐based conceptualization of deforestation and restoration in policymaking, however, results in missed opportunities for addressing deforestation and restoration. Here, we explore the drivers of deforestation, the perceptions of restoration, and the challenges to restoration among smallholder farmers in northern Malawi and examine how agroecology can contribute to restoring degraded agroecosystems. Participants report agricultural land expansion, charcoal production, climate change, burnt brick production, and government subsidies as the major drivers of deforestation. We observed that although perceptions of forest restoration reflect farmers' traditional ecological knowledge (TEK) to include reclamation of degraded farmlands, reconstruction of native tree species, and replacement of felled trees on farmlands, there are challenges including splitting families to gain access to more subsidized fertilizers and food aid, embedded cultural practices, growing demand for charcoal in cities, and weak ecosystem governance structures that hinder the effectiveness of restoration efforts. We, however, do find that agroecological intensification can increase yield from smaller farmlands and allow for larger and longer‐lasting fallows of spare lands which regenerate forests. Key overarching implications of these findings include the need to integrate livelihoods more explicitly into restoration plans, accounting for TEK in restoration policies in forest‐dependent communities and encouraging the adoption of agroecology.

Assessment of sandcrete hollow blocks’ thermal performance as a walling material for tropical buildings in Lokoja, Nigeria

PurposeUnderstanding the thermal performance of sandcrete hollow block walls in the tropic is very essential for occupants' well-being, productivity and efficiency, due to its widespread application in buildings in the study area. Lokoja, in Nigeria, lies in the warm humid zone with its attendant's high temperatures all year round. Thus, providing an acceptable walling material that will control the high indoor air temperature becomes imperative. This paper assessed sandcrete hollow blocks as a walling material used in Lokoja, to determine the thermal performances for effective thermal comfort of the residents.Design/methodology/approachIt involves the construction of a habitable model building with the commonly available sandcrete hollow blocks in the area. One unit of Cryopak iMINI Temperature and Relative Humidity Data Logger called new generation intelligent iMINI with Serial Number and Product Code MX-CI-145–0009 and MX-HE-S-16-L was installed, to record the indoor air temperature and relative humidity data at an interval of one hour, for 12 months covering dry and wet seasons. The results of the recorded data were downloaded to an excel spread sheet for assessment and analysis throughout the seasons. The values were computed using the temperature–humidity index (THI) equation, with a view to determine the indoor thermal comfort level category.FindingsThe study revealed that sandcrete hollow block walls provide thermal discomfort of the indoor environment for both seasons, with attendant adverse effects in the comfort of the occupants. The paper concludes that proper orientation of buildings, planting of trees, use of low absorbing or reflective surface materials, application of cavity walls to receive insulation materials in between the hollow spaces provided, instead of the single walling as well as providing shading device elements, can improve users' comfort and also ameliorate the heat effect on the external surface of building transferred into the interior by conduction, radiation or convection within the area and in the tropics at large. Other thermally eco-friendly wall materials available in Lokoja includes timber, stabilized laterite–cement blocks, burnt bricks and earth-mud bricks which can be used to replace sandcrete hollow block walls. These alternative wall materials are used for construction of residential and office buildings by the colonial government of Sir Fredrick Lugard in the study area.Practical implicationsThe application of sandcrete hollow blocks as a wall material is in vogue, not minding its thermal discomfort to the users and the environment; this is due to its availability and ease of production. The acceptability of this walling material requires holistic study to unravel the best way to reduce the thermal discomfort inherent in its application.Originality/valueThe author succeeded in revealing the thermal performance of sandcrete hollow blocks as walling material in Lokoja, the study area. It is a first attempt at understanding the performance for human comfort in the area. This will greatly assist the resident and other researchers to improve on the application of sandcrete hollow blocks as walling material towards ensuring that maximum indoor thermal comfort is achieved.

IMMOBILIZATION OF HIGH-LEADED CATHODE RAY TUBE GLASS IN FIRED CLAY BRICKS BY RECYCLING

End-of-life cathode ray tubes (CRTs) have become global problem in the pool of waste electrical and electronics owing to higher concentration of lead (Pb) and this needs urgent management in an ecofriendly manner. In this study, spent CRT glass was incorporated in clay to make burnt bricks for construction. Samples of CRT glass were collected from technicians’ workshops, manually dismantled, pulverized, milled and sieved into three particles sizes (PS), namely; 0.6mm ≤1.0mm, ≤2.0mm. The metallic composition was determined with Inductive Coupled Plasma- Optical Emission Spectrometric technique (ICP-OES). Each PS was mixed with clay at percentages ranging from 0% as control to 15% CRT and moulded using dry compression technique, dried and fired in furnace at 800 0C. Mechanical properties of fired bricks products were assessed including water absorption, linear shrinkage and compressive strength. The 4wt% CRT-clay composition for ≤0.6mm PS exhibited highest strength with low linear shrinkage and medium water absorption and was selected as optimum composition. Lead (Pb) leachability from fired CRT-glass/clay from the three particle sizes using TCLP and SPLP were within permissible limit of 5.0mg/L set by US-EPA. The total recoverable lead (Pb) from optimum test composition was 96mg/L or 96,000 mg/kg that exceeded the permissible limit. From the findings, it can be shown that the optimum composition of less than 0.6mm particle size is of good quality, durable and environmentally safe bricks that can be used for building construction works.
