Influence of the size of soursop seed granules on the mechanical and water properties of compressed earth bricks

The use of plant raw materials in Compressed Earth Bricks has become an increasingly a common practice. This present work is part of this approach; it aims to study the impact of the size of soursop seed granules on the mechanical and water properties of Compressed Earth Bricks (CEB). To do this, clay named Aga from Gagnoa consisting essentially of quartz (77.13 wt%) and clay minerals kaolinite and illite (21.28 wt%) and soursop seeds of fine particle size (d≤0.5 mm) and average (0.5<d<1mm) were used. The results of the mechanical tests showed a drop in compressive strength of 37% and 44% respectively for the formulations with fine granules and medium granules compared to the resistance of the formulation with raw clay. The formulation with fine granules (A94GF6) therefore presents the best compressive strength (3.58 MPa). In terms of water absorption by capillarity, the formulation with fine granules has greater absorption with an absorption coefficient of 0.2824 kg.m-2s-1/2 compared to the formulation with medium granules in which their absorption coefficient is 0.1143 kg.m-2s-1/2. All the results showed that seed granules can be used in compressed Earth Bricks, however it is recommended to use them with a fine particle size (d ≤ 0.5 mm).

Evaluating Thermal Performance and Environmental Impact of Compressed Earth Blocks with Cocos and Canarium Aggregates: A Study in Douala, Cameroon

A novel low-cost earthen construction system integrating biosourced aggregates is proposed for houses’ erection of low-income households. This study is based on in-situ measurements on two representative test cells constructed in Douala, with a typical hot and humid climate. One of these buildings is made with a hollow cement block as a reference, and the other with biosourced earth bricks modified with Cocos nucifera and Canarium schweinfurthii aggregates. Dynamic thermal simulations of the two test cells were performed using the EnergyPlus building performance simulation program. The results are based on measuring air temperature and humidity, and the simulation leads to defining the discomfort hours and the annual energy consumption. The adaptive ASHRAE 55 thermal comfort model was used to evaluate the comfort conditions. The results show that air conditioning systems provide the best comfort systems with minimums of about 95% for plastered and unplastered wall construction systems. Biosourced compressed earth brick constructions offered the best thermal performance with comfort ranges of around 96% and 44% for air conditioning and natural ventilation, respectively. In terms of energy consumed, there was a gain of about 100 kWh over the year. Energy consumption is lower in the biosourced compressed earth brick building than in the hollowed cement block building: this one offered the lowest comfort range of about 40% in natural ventilation. The construction provisions were considered for the life cycle assessment, and two scenarios describing the origin of the cement raw materials were considered. It can be seen that cement accounts for more than 95% of the impacts for both construction systems, as well as for the scenarios of its origin. In all situations, the hollowed cement block construction presented the highest impact on the global warming potential: 66 KgCO2eq and 89 KgCO2eq, respectively, without plaster and with plaster. It can also be seen that the plastered layer had a carbon footprint (in terms of Green House Gas Emissions (GHG emissions)) of almost 40% on the overall functional unit. Canarium Schweinfurthii and Cocos Nucifera materials accounted for only 1% of the overall impact.

Effects of Recycled Expanded Polystyrene Beads on the Mechanical and Physical Properties of Cement-Stabilized Compressed Earth Bricks

Nowadays, research on environmentally friendly materials has become a significant challenge in the field of civil engineering. In this study, stabilized compressed earth bricks (CEBs) incorporating recycled expanded polystyrene (EPS) beads were studied with the aim of enhancing the development of green constructions. The mass contents of recycled EPS in CEB formulated at a compaction pressure of 5 MPa are 0%, 0.25%, 0.5%, 0.75%, and 1% relative to the mass of the soil, while cement type CEM I 32.5, as a stabilizer, constituted 8% by mass. Characterization was carried out by determining densities, dry and wet compressive strength, flexural strength, total water absorption, and capillarity. Sample properties were found to be strongly influenced by the percentage of recycled EPS. Increasing the EPS aggregate content led to a reduction in compressive strength in both wet and dry conditions. Samples with 0.5% EPS and 8% cement offered better physical and mechanical performance. Samples containing EPS had relatively low water absorption, which would contribute to good durability. These CEBs comply with the wall construction requirements for two-story dwellings. This study also demonstrates the potential use of this recycled material in the construction industry.

Effect of Wood Biomass Ash on the Mechanical and Thermal Performance of Compressed Earth Bricks

AbstractThis present study investigates the recovery of wood biomass ash (WBA) as chemical stabilize in compacted earth bricks. The specimens were tested for compressive and thermal properties in dry state. The tests were performed at 7 and 28 days of age in order to evaluate the effect of the partial substitution of soil with WBA on the mechanical and thermal properties of the compressed earth bricks. The results indicate that bricks manufactured with 20% of partial substitution showed better performance than those containing only soil. Nevertheless, the use of WBA as source of lime improved the compressive strength and the thermal conductivity of the bricks stabilized with different proportions (5, 10, 15 and 20% wt) when compared with bricks fabricated with 100% soil. This improvement is owing to the pozzolanic reaction produced between the soil components and the WBA as well as the soil microstructure. It was also concluded that the combination of the soil components and lime containing in WBA in the stabilization of compressed earth bricks seems to be a promising alternative when considering issues of energy consumption and pollution.

Thermal comfort in a building constructed of FOAM concrete made in Burkina Faso

Thermal comfort is a feeling of well-being in a given environment. In the context of sustainable development, new regulations on thermal insulation in the building sector are leading researchers to design new materials for energy-saving systems and ensuring comfort in the habitat. We highlight the effects induced by the use of Pr. Blanchard's foamed concrete (FC) in construction in order to reduce energy consumption and ensure hygrothermal comfort in the home. This article numerically studies the thermal comfort for buildings constructed with materials such as foamed concrete, cinder block, compressed earth brick (CEB), adobe and cut laterite block (CLB). The comparison of the hygrothermal behavior (temperature and relative humidity) of premises made of different materials was carried out with three typical climates (January: dry and cold period, April: dry and hot period and August: humid period and mild temperature) under climatic conditions of Ouagadougou in Burkina Faso. The results showed that for the months of January, April and August the temperatures of the foamed concrete room (FC-930, thickness: th=17.5 cm) having respectively values of 296 K, 304 K, and 298 K is always lower to other materials. The relative humidity of the foamed concrete cell (FC-930, th=17.5 cm) in the months of January, April and August has values of 19%, 31 % and 63.7 % respectively which are also higher than those of the cells built with several local materials. Thus, a building constructed with foamed concrete has better thermal comfort than those made of concrete block, CEB, adobe and CLB.

Study of the Influence of Corn Stalks Fibers on the Characteristics of Compressed Earth Bricks

The objective of the present study is to determine the optimal dosage of corn stalks fibers to obtain good resistance of compressed earth bricks. After determining the properties of the fibers and the clay soil, a volume variation of the fibers is carried out in relation to the mass of the mixture for making bricks of dimensions 10.5x22x6.5 cm3 which are stored in a sheltered place. On these bricks, the densities and compressive strength are determined at 28 days of age. Both poorly graded and well graded fibers are used in this study. From this study it appears that the fibers are light and that the earth is not very plastic, containing no humus. The density of the bricks decreases and the resistance increases with the increase in the fiber content. Resistance is better with well graded fibers. Keywords: corn stalks, compressive strength, clay soil, fibers.

Method of choosing soils as CEB or pavement layers based on geological and environmental information and mode of treatment

During research on the geological, mineralogical, mechanical and geotechnical nature of thick layers of soils developed on the rocks of the lower zone of the southern slopes of Mount Bambouto (West Cameroon), a couple of observations were made. The mechanical behavior of soils as construction materials is linked to the nature of the parent rock and its environment of formation. Four different types of rock have been noted: trachybasalt, orthogneiss, anatexite, and biotite-hornblende granitoid. These rocks in a hot and humid mountain climate, exposed to the monsoon wind, have weathered to give soils with exploitable characteristics in compressed earth bricks (CEB) and pavement layers. This article proposes a method of choosing a soil for pavement layers and for the production of fired earth bricks / earth bricks treated or not with hydraulic binders, based on the nature of the bedrock and the climatic environment. Several formulation models have been defined. The performance, fairness, accuracy and adequacy of these models with real values were made by metric evaluation. So, it is:•Preliminary method for quickly and easily formulating masonry units in clay soil.•Preliminary method for quickly and easily formulating pavement layers in clay soil.•Simple and reliable method for choosing clay soils as construction materials from elementary geological information.

A Study of Performance of Compressed Earth Brick Incorporation with Waste Fire Clay Brick as a Filler

This study examines the use of waste fire clay brick as a filler in compressed earth brick production. The purpose of this study is to determine the compressive strength and water absorption of the compressed earth brick incorporation with waste fire clay brick as a filler. The optimum amount of waste fire clay to utilize as a filler is also being studied. A total of 72 compressed earth bricks were produced with the brick size of 125 mm x 250 mm x 100 mm which consist of a mix of sand, soil and cement with mix proportion of 1:4:4. A few tests were conducted which are compressive strength test and water absorption test. The waste fire clay bricks were utilized in this study and replace by volume fraction percentage of 10%, 20%, 30%, 40% and 50% while 0% is set as the control. The findings obtained show that the compressive strength of the bricks was increasing. The percentage of water absorption were decreasing along with the increases of percentage of waste fire clay brick as a filler.

Influence of Diatomite on the Physico-Mechanical Properties of Compressed Earth Blocks

Given the need for decent housing and taking into consideration the environment, as well as the search for sustainable materials, in recent years researchers have begun to focus on local biodegradable and ecological materials. It should be noted that the use of building materials evolves in step with population growth. However, their production must have a clear positive impact on the environment and offer viable solutions for reducing energy consumption during it is application. However, these materials rarely meet the mechanical requirements for using in housing construction. The aim of this study is to investigate the potential use of diatomite in the manufacture of compressed earth bricks. Diatomite is used at between 5% and 50% in two clay soils to determine its physico-mechanical properties. The study focused on shrinkage and mass loss, density, porosity, flexural strength, compressive strength and splitting tensile strength of the composites. The results show that the incorporation of diatomite improves the linear shrinkage of compressed earth blocks and increases their porosities. The dry density of compressed earth block decreased considerably with increasing percentages of diatomite, which also led to a reduction in mechanical strength. This reduction in mechanical strength is linked to the physicochemical characteristics of diatomite. According to a number of relevant standards in the literature, which can be used in building construction set minimum permissible strengths at 2 MPa in simple compression and 0.1 MPa in bending and indirect tension, composites made from two clay soils and diatomite.

A comparative study of compressed lateritic earth bricks stabilized with natural pozzolan-based geopolymer binders synthesized in acidic and alkaline conditions

Two geopolymer binder systems made under alkaline and acidic conditions have been evaluated for the stabilization of compressed lateritic earth bricks (CEBs) using natural pozzolan as aluminosilicate precursor. The preparation of alkaline and acidic activators involved the combination of sodium silicate and 10 mol/L sodium hydroxide solutions, as well as 10 mol/L phosphoric acid solutions, respectively. CEBs were prepared to comprise different proportions of natural pozzolan of 5, 10, 15, and 20 %. The physico-mechanical and mineralogical properties of compressed earth bricks were studied using the compressive strength, the dry and wet bulk density, the water absorption rate, Fourier transform infrared spectroscopy (FTIR), powder X-Ray Diffraction (PXRD) and optical microscopy (OM).The results showed that in the acid environment, the mechanical performance increased considerably with the pozzolan content and slightly with the curing time, whereas in the alkaline environment these performance decrease for the sample with 0 to 10 % of pozzolan and remain constant for the sample with 15 to 20 % of pozzolan after 14 days of curing. The utilization of acid-activated geopolymer binder in the production of laterite-based compressed earth bricks has been shown to be more effective compared to the utilization of an alkali-activated geopolymer binder. The high performance of acid-stabilized CEBs is related to the best reactivity of natural pozzolan in acid medium allowing the formation of Al-O-P bonds.

Engineering properties of cement-stabilized compressed earth bricks

The significance of knowing the engineering properties of cement stabilized compressed earth brick (CSCEB) becomes useful within the context of manufacturing, construction, and the associated business domains, mostly at the local level. Chemical and mechanical stabilization techniques play a vital role in the production of soil bricks with adequate engineering properties. Cement, one of the most used chemical stabilizers, is the only easy approach of locally in the context of many developing countries. The study of soil bricks with such stabilizers will eventually benefit local-level manufacturers. This experimental study aims to assess the certain structural and durability properties of two categories of CSCEB samples: one with zero percent sand and another with forty percent sand content, mixed with clay soil constituting a total of eight sample types. The proportion of ordinary portland cement varied from five to twenty percent in intervals of five for both sample categories. The CSCEBs were evaluated through structural properties, including dry compressive strength, wet compressive strength, and three-point bending tests. To understand the durability property, a moisture absorption test was performed. The results showed that an increase in cement content led to higher dry and wet compressive strength and bending strength for both sample types. Additionally, increasing the cement content resulted in decreased water absorption for both samples. These findings complied with national and international specifications at a certain stage. The sample containing sand demonstrated superior engineering properties compared to the sample without sand.

Characterization of basaltic rock laterites in Dschang, West-Cameroon: Compressed Earth Bricks (CEB) for low-cost buildings

This study reports on the geotechnical characterization of lateritic soils upon basaltic rocks in Dschang, West-Cameroon. Six (06) soil samples from six (06) sites were taken for assessing their suitability in good quality CEB manufacturing. An analytical approach was adopted and consisted of standard physical and mechanical properties including water content, absolute density, Atterberg limits, grain size distribution and Optimum Proctor Modified (OPM). Mineralogical and geochemical contents of the materials were obtained by X-ray diffraction (XRD) and X-ray fluorescence (XRF) respectively. In addition, density, water absorption, abrasion resistance, and dry and wet compressive strengths were determined for manufactured brick specimens. Results indicate that the materials are rich in kaolinite (33–38%), gibbsite (21–27%) and goethite (22–26%) associated to low proportions of smectites (2–7%) and oxides such as hematite, ilmenite, anatase and bohmite. SiO2 (29.57–35.8%), Al2O3 (22.72–26.93%) and Fe2O3 (20.67–27.95%) are the most abundant oxides while basic cations are generally low in the materials (WIP: 2.25–5.89). The absolute density varies from 2.26 to 2.57 t/m3 and could be indicative of higher Fe2O3 contents. The plasticity index (7.80–18.95%) and the liquidity limit (57.80–64.50%) of materials allow their classification as inorganic silt and organic clay with high plasticity and compressibility that are not suitable for the production of CEB. Furthermore, these materials fall out the preferential plasticity domain recommended by Cameroonian standard for CEB. Based on grain size distribution, the studied materials also fall out the sprindle reference of the Cameroonian standard. For improving the characteristics of studied materials, a grain size correction was performed and provided an optimal mixture made up of 75% natural materials and 25% medium sand (0.05–0.5 mm) that is locally available. This is accompanied by considerable variations of consistency parameters allowing to pass from inorganic silt and organic clay to inorganic clay that display appropriate compressibility and plasticity for good quality CEB production. The using of cement at 4%, 6% and 8% revealed a progressive increase of the MDD (1.40–1.77%) and Wopt (12.60–28.39%). Moreover, the density and mechanical parameters of the manufactured specimens increase with the cement content. The density, physical and mechanical properties of the manufactured specimens fall within the Cameroonian standard of compressed earth bricks (CEB). Globally, the lateritic materials of Dschang improved with sand (25%) and Cement (8%) can be suitable for the production of good and low-cost CEB especially as the two additional materials are locally available and accessible.

Carbon Emissions Due to Construction of Building Using Cement-Stabilized Compressed Earth Bricks and Comparison with Conventional Fired Earth Bricks

Carbon emission from human activities including civil engineering constructions has been a major global environmental issue. The emissions due to the use of conventional fired earth bricks (CFEB) in the construction industry are significantly larger, and a large number of researches have been devoted to developing viable alternatives to the uses of CFEB in the construction industry to achieve a low-carbon society. This research investigated carbon emissions due to the use of cement-stabilized compressed earth blocks (CSCEB) in place of CFEB in the construction of a community building in Bidur Municipality, Nuwakot, using the standard tools and methods by the Intergovernmental Panel on Climate Change (IPCC) guidelines. Also, the Bilan Carbone tool was used. Then the emission results of the two cases (CSCEB and CFEB) were compared from different perspectives. Among the considered major emission sectors, the construction materials sector contributed the highest carbon emissions in both bricks. Results indicate that CSCEB requires lower quantities of cement, sand, and aggregates compared to CFEB. Major construction materials contribute significantly to carbon emissions, with CSCEB showing a 1.7 times lower impact than CFEB. The total carbon emissions for CSCEB and CFEB were 160.97 and 206.42 Tons of CO2 equivalents in this study. That is, the total carbon emission from CFEB construction was about 1.3 times of the CSCEB. Furthermore, the direct emissions in both cases were almost the same, while the 1.4 times larger emission in the case of CFEB was the sole contribution of indirect emissions. The results of this study once again demonstrated that CSCEB can be an alternative to CFEB in the construction industry to achieve the objective of a low-carbon society.

Mineralogical, geochemical, and geotechnical features of lateritic soils from termite mounds in two contrasting savannah areas (central Cameroon) as raw materials for brick making

Termite mound soils (TMS) from humid savannah (HS) and dry savannah (DS) were evaluated as raw materials for compressed earth bricks (CEB) and fired bricks. Mineralogy and major elements geochemistry were performed by X-Ray Diffraction and X-Ray Fluorescence, respectively. Physico-mechanical characteristics of unfired and fired bricks at 900, 950, 1000, 1050, and 1100 °C after 7 curing days were evaluated. The studied TMS are made up of quartz, muscovite, anatase, kaolinite, hematite, and goethite. Illite is present in humid savannah while in DS gibbsite appears. These materials are rich in SiO2 (58.96–61.79 wt%), Al2O3 (16.93–18.78 wt%), and Fe2O3 (7.41–10.33 wt%). The TMS from both HS and DS are sandy clay. Those from DS are silty (13%) than those from HS (<5.7%). Termite mound materials in DS are moderately plastic, while those in HS are highly plastic. Flexural strength values vary between 2.20 and 2.38 MPa for unfired bricks and between 2.41 and 3.26 MPa for fired bricks, respectively at 1100 and 1050 °C. Compressive strength values are ranged from 2.01 to 3.50 MPa for unfired bricks and 2.44 (1100 °C) to 11.08 MPa (1050 °C), with the best values in the DS area. Water absorption and linear shrinkage values are less than 25% and 5%, respectively, in the studied fired and unfired bricks. The physical and mechanical properties of unfired and fired bricks show that the studied TMS can be used for dense brick manufacturing. Materials from dry savannah exhibit better characteristics as construction materials due to relatively high weathering intensity leading to a spread-out particle size distribution, sintering, which promotes densification by reducing the porosity, and the conversion of metakaolinite into primary mullite upon temperature increase.

Valorization of cotton waste ash in the formulation of compressed earth blocks

We characterized the mechanical and thermophysical properties of the compressed earth bricks (CEB) incorporating cotton waste ash. The obtained values of compressive strength are acceptable, as they are well above the limits set by the standards for CEB in Cameroon. Regarding the thermophysical properties, the measured heat capacity decreases by 17% compared to cement stabilization, which is an improvement in the material’s ability to store heat. Thermal conductivity is reduced by 28% compared to the cement formulation. Therefore, the incorporated material improves the natural thermal comfort of buildings. Water absorption tests have shown that these materials absorb less water.

Cost-effectiveness and affordability evaluation of a residential prototype built with compressed earth bricks, hybrid roofs and palm midribs

As a response to rising housing prices and the high cost of materials in the building and construction industry, a rural prototype house (the Ecofordable House) was built with alternative technologies. The house is located in the western desert zone of Giza, Egypt, and features enhanced vernacular technologies with local materials. Interlocking compressed stabilized earth brick walls, partially reinforced, jack arch and funicular shell roofs, and date palm midribs were employed in an attempt to reduce the usage of steel, fired bricks, cement, and imported wood. The present research evaluates the house’s construction cost-effectiveness and affordability through detailed real-world data and comparisons of material quantities, labor, and costs with those of conventional methods. The “price-to-income ratio” is used as an indicator of affordability. According to the findings, walls cut costs by half, roofs by a quarter, and midribs by two-thirds; the alternatives combined saved 45%, and the house saved a quarter of the cost after adding common expenses. Moreover, less than one-third of steel, fired bricks, and cement were utilized. In the Egyptian context of government-built houses, the prototype would be affordable for most Egyptian income brackets while the conventional house was expensive for the lowest three. The findings provide empirical support for the economic advantages of enhanced vernacular technologies as alternatives and address residential affordability in similar contexts.

Effect of reinforced recycled sawdust-fibers additive on the performance of ecological compressed earth bricks

This study assesses the potential of waste wood sawdust, as a construction material additive, on the mechanical, thermal and physicochemical properties of compressed earth bricks. Following X-Ray Diffraction and Fluorescence analysis, the used raw clay material, retrieved from Ifrane, Morocco, was found to be of type Illite, with a prominent SiO2 content, 59.60%, making it a suitable construction material. Multiple waste additive proportions were analyzed (0%, 1%, 3%, 7%, 15% and 20%), by weight, at different sizes: small size: (δ ≤ 0.5 mm), medium size: (0.5 mm < δ ≤ 1 mm), and large size: (1 mm < δ ≤ 3 mm). The incorporation of higher recycled sawdust waste additive content at larger sizes produced bricks with higher porosity levels. This resulted in manufacturing lightweight brick structures, below the 1.70 g/cm3 permissible limit, with higher water absorption rates. Improvements in compressive strength in prepared samples were observed with the incorporation of smaller additive sizes. In fact, 3% additive specimens recorded a 6.05 MPa at larger sizes, compared to 7.69 MPa with smaller additive sizes, reflecting a 22% mechanical compressive strength gain. Produced samples manifested enhanced thermal performances with the use of the sawdust waste additive in the 60% and 36% range for thermal conductivity and specific heat capacity, respectively; in addition to recording prominent energy savings in terms of thermal heating and cooling loads, with energy gains in the 50% interval. Theoretical models were developed to test the accuracy of the experimental findings. An obtained good correlation coefficient, very close to 1, corroborated the accuracy of the collected findings.

Experimental thermophysical dependent mechanical analysis of earth bricks with Canarium schweinfurthii and Cocos nucifera bio-aggregates - A case study in Cameroon

In order to meet sustainable development goals, global policies are strongly oriented towards the recovery of local materials such as agricultural waste. In this context, a new biosourced compressed earth brick (CEB) has been produced with bio-shell aggregates of Cocos nucifera (CN) and Canarium schweinfurthii (CS), added in equal proportions for various mixtures. The main objective is to study, on one hand, the effect of CN and CS aggregates on the mechanical behaviour and the thermo-physical properties of the CEB. On the other hand, durability of CEB was investigated in terms of hydric stability, abrasion resistance and hygro-thermo-mechanical behaviour. Mixtures were prepared using earthen material and 0, 5, 10 and 15 wt% CNCS, with 8 wt% cement CEM II-B-LL 42.5, respectively. Wet and dry compressive strengths are evaluated versus compaction pressure (2.5, 5, 7 and 10 MPa). The increase of CNCS aggregate content induced a reduction of the compressive strength in both wet a\nd dry situations whatever the compaction pressure. The samples with 5 wt % CNCS and 8 wt % cement, however, offered performances close to reference samples without CNCS aggregates. The reverse trend was found for thermal conductivity: thermal conductivity of the bio-sourced CEB is below 1 W·m−2·K−1 which means good insulating performances. It is noted that the modified CEB have relatively low water absorption, which contribute to a good durability. Hygro- and thermo-mechanical tests showed however a quasi-linear decrease of compressive strength when the humidity of the environment increases but also when the temperature rises. At the end, to obtain more accurate properties by prediction, some machine learning models were used.
