Pemanfaatan Sekam Padi (Oryza sativa) Dan Cangkang Kerang Totok (Geloina sp.) Sebagai Bahan Campuran Paving Block

Shellfish shells and rice husks can be processed into charcoal and ash. Shellfish ash and rice husk charcoal contain chemical compounds such as pozzolan, lime (CaO), alumina and silica compounds which can replace cement in paving block mixtures. The use of rice husk charcoal and full-blooded clam shell ash as an alternative provides stronger pressure resistance. This research aims to determine the effect of the composition of a mixture of shell ash and rice husk charcoal on the quality of paving blocks. The results of this research were a mixture of composition A3 (2:1) with 66.6 grams of rice husks and 33.3 grams of full-blooded clam shells as well as 500 grams of cement and 1500 grams of sand, resulting in a compressive strength of 14.3 Mpa and was classified as C. Composition A5 (3:1) mixture with 25 grams of rice husks and 75 grams of full-blooded clam shells as well as 500 grams of cement and 1500 grams of sand, produces a compressive strength of 16.7 Mpa and is classified as B. Meanwhile, the composition of the A0 (0:0) mixture without A mixture of rice husks and shells only produces a compressive strength of 9.05 Mpa and is classified as D. The conclusion of the research is that paving blocks of composition A5 show the best water absorption quality with water absorption results of 7.69%.

Bearing capacity of Percut Sei Tuan clay stabilized with palm shell ash

Improvements to the bearing capacity of the soil have been carried out and developed at this time, one of which is the stabilization of clay soils. There are several alternatives to solve low soil bearing capacity, one of which is using geo-synthetic materials but has a weakness in terms of high cost. Another alternative is to add palm shell ash as a stabilizing agent. The effect of adding palm shell ash has not been thoroughly studied, so further research is needed. The material added is palm shell ash with a variation of 0%, 4%, 8%, 10%, and 12% in each test. The tests carried out in the laboratory were water content (w), specific gravity test (Gs), Atterberg limit test, sieve analysis (sieve analysis), soil compaction test, and CBR (California Bearing Ratio) test. The CBR test was carried out by curing the soil for 1, 3, 5, and 7 days with a mixture of palm shell ash before compaction. The soil in this study belongs to the A-7-5 group. The CBR (California bearing ratio) value increased with the increase in the palm shell ash percentage in the mixture after curing the soil. The highest CBR value was in the variation of 12% palm shell ash with a 7-day curing period of 6.92% with a soil bearing capacity of 5.06.

Utilization of Ipomoea batatas L. tuber extract for the development of dye-sensitized solar cell with modified electrode from rice husk ash

A dye-sensitized Solar Cell (DSSC) is a solar cell device that works based on electro photochemical principles in which sensitive dyes are absorbed in the layer of photoelectrode. The utilization of natural dyes as a substitute for high-cost material in DSSC has been developed. Purple sweet potato (Ipomoea batatas L.) has high anthocyanin content, is safe to use, and has renewable properties that can be used as dyes in a layer of DSSC. Purple sweet potatoes contain a lot of fiber, carbohydrates, vitamins C and B1, and minerals needed in DSSC. The semiconductor compiler to produce solar cells is expensive and requires many. Rice husk has a relatively high silica content, about 87-97%, that can be used as a low-cost and environmentally friendly silicon. The result of this study showed the absorbance peak for the mixture of extract and rice husk ash at 320 nm. DSSC fabrication obtained the highest efficiency of 1.1 x 10-3 with Imax = 0.0015 mA and Vmax = 0.02 mV. The physical characteristics were observed using SEM and XRD. Natural dye from purple sweet potato and rice husk ash semiconductors can be alternatives for DSSC production.

Analisis Kuat Tekan Beton dengan Pemanfaatan Silica Fume dan Fly Ash Sebagai Pengganti Semen Sebagian

Construction activities require concrete as a widely used material. Concrete consists of several compositions, namely fine aggregate, coarse aggregate, water, and Portland cement as the main material for the binder. Cement production contributes around 6% of carbon emissions which can damage the environment, including global warming, and the use of high levels of cement material in concrete mixtures, so alternative materials are needed to replace cement or cement additives for concrete mixes. Alternative materials used in this research are fly ash and silica fume. This research aims to determine the test results and characteristics of concrete using silica fume and fly ash as partial cement substitute materials as well as the effect of the ratio of silica fume and fly ash on the compressive strength of concrete. The research was carried out by direct testing in the laboratory. The various mixtures of Fly Ash (FA) and Silica Fume used are: FA 10% and SF 5%, FA 15% and SF 5%, FA 20% and SF 20%, FA 25% and SF 10%. Based on the results of compressive strength tests carried out at 28 days of concrete, it shows that the use of silica fume and fly ash to replace cement cannot be said to have succeeded in increasing the strength of the concrete. The highest compressive strength value was achieved by variation 3, namely with a fly ash content of 20% and 10% silica fume, producing a compressive strength value of 19.44 Mpa, this shows that the strength achieved is still limited to low quality concrete below 20 Mpa.

Durability, Capillary Rise and Water Absorption Properties of a Fiber-Reinforced Cement-Stabilized Fly Ash–Stone Dust Mixture

The management of unutilized fly ash poses challenges due to concerns about storage and its potential groundwater contamination. Within the road industry, where the bulk utilization of fly ash is feasible, its unsuitability for use in the base and sub-base layers of pavements due to its low strength and a high proportion of fine particles has been a limitation. The incorporation of stone dust alongside fly ash, treated with lime or cement, yields superior strength and stiffness. Apart from strength, the stabilized mix’s durability, capillary rise, and water absorption properties are crucial for determining its suitability for pavement applications. Observations from this study reveal that fiber-reinforced cement-stabilized fly ash–stone aggregate specimens treated with 4% and 6% cement, with and without fibers, met the limiting mass loss of 20%, as specified in IRC SP: 89. The mass loss decreases with an increase in cement and fiber content. However, the capillary rise in the mixes increases with a higher percentage of fly ash and fiber content but decreases with increased cement content. Cement addition results in a reduction in water absorption; however, the addition of fibers results in an increase in water absorption. A linear correlation has been established between mass loss and UCS and IDT, which can be used to evaluate the suitability of materials for the structural layer without conducting a wet–dry durability test, which typically takes one month. This study proposes that cement-stabilized fly ash and stone aggregate mixtures with 4% and 6% cement can be used as the subbase and base of pavement based on wet–dry mass loss criteria and water absorption criteria.

Evaluation of calcium carbide residue and fly ash as sustainable binders for environmentally friendly loess soil stabilization

The incorporation of waste materials into cementitious binders serves as a strategy to diminish waste volume and lower carbon emissions. This study presents an in-depth evaluation of calcium carbide residue and coal fly ash as alternative binders. The assessment of raw materials emphasized their chemical composition and potential for pozzolanic reactions. Based on these factors, the optimal ratio of Ca/(SiO2 + Al2O3) in the raw materials was determined to be 1.5. Therefore, this study was designed to vary the raw material composition with a CaO/(SiO2 + Al2O3) ratio ranging from 1.7 to 0.9. Upon investigating the effect of the raw material proportion on the compressive strength of pastes and mortars, the composition yielding the highest compressive strength was selected for its potential application as a stabilizer for loess soil. A mixture of calcium carbide residue and coal fly ash with a Ca/(SiO2 + Al2O3) ratio of 1.5 resulted in the highest compressive strength at long curing periods in both pastes and mortars. Mineralogical and microstructural analyses revealed several products, beyond those formed from the pozzolanic reactions, that occurred and enhanced the compressive strength of samples. The highest performing mixture of carbide residue and coal fly ash was then used to stabilize loess soil at 10–25 wt%. The unconfined compressive strength, along with mass and strength loss due to wetting and drying cycles, was also studied. It was observed that the unconfined compressive strength of the stabilized soils remained consistent after six wet-dry cycles but decreased after twelve cycles due to microcracks. The findings suggest that carefully designed mixtures based on the chemical interactions of calcium carbide residue and coal fly ash can offer a sustainable, efficient approach for soil stabilization, potentially revolutionizing construction practices.

Cementless concretes, based on anthropogenic wastes of the Irkutsk Oblast

The accepted global trend of transition from a linear economy to a closed-loop one stimulated the development of regulatory documents, such as “Strategy for the development of building materials in the Russian Federation and Irkutsk Oblast”, Decree of the Government of the Russian Federation dated 08/02/2023 No. 2094, both at federal and regional levels. Further, the Baikal interregional scientific and educational centre was established. All this aims at obtaining technologies for developing effective building materials, based on technogenic wastes, and establishing the production. It is planned to obtain effective building materials, based on the accumulated high-tonnage waste of the Usolye-Sibirskoye priority development area, such as ash and slag mixtures of the combined heat and power plant (90 million tons) and lime-containing waste, generated during the production of acetylene at the Khimprom PJSC (more than nine million tons). The paper represents a fundamentally new approach to obtaining artificially synthesised newgrowths of cementless concrete, based on technogenic wastes, which meets the requirements of regulatory standards in terms of frost and water resistance and allows using this concrete in enclosing structures. At a rationally selected ratio between lime-containing wastes and an ash-slag mixture, subject to the pre-established principles of technological preparation in terms of their mechanical activation, mixing technology, conditions and synthesis duration, it is possible to obtain high-quality cementless concrete that meets the basic requirements of regulatory documents for quality indicators.

Compressive strength prediction and low-carbon optimization of fly ash geopolymer concrete based on big data and ensemble learning.

Portland cement concrete (PCC) is a major contributor to human-made CO2 emissions. To address this environmental impact, fly ash geopolymer concrete (FAGC) has emerged as a promising low-carbon alternative. This study establishes a robust compressive strength prediction model for FAGC and develops an optimal mixture design method to achieve target compressive strength with minimal CO2 emissions. To develop robust prediction models, comprehensive factors, including fly ash characteristics, mixture proportions, curing parameters, and specimen types, are considered, a large dataset comprising 1136 observations is created, and polynomial regression, genetic programming, and ensemble learning are employed. The ensemble learning model shows superior accuracy and generalization ability with an RMSE value of 1.81 MPa and an R2 value of 0.93 in the experimental validation set. Then, the study integrates the developed strength model with a life cycle assessment-based CO2 emissions model, formulating an optimal FAGC mixture design program. A case study validates the effectiveness of this program, demonstrating a 16.7% reduction in CO2 emissions for FAGC with a compressive strength of 50 MPa compared to traditional trial-and-error design. Moreover, compared to PCC, the developed FAGC achieves a substantial 60.3% reduction in CO2 emissions. This work provides engineers with tools for compressive strength prediction and low carbon optimization of FAGC, enabling rapid and highly accurate design of concrete with lower CO2 emissions and greater sustainability.

Removal of selected contaminants of the soil and water environment on a model isolation barrier

Landfill leachate poses a threat to the soil and water environment. Protection against their migration is provided by sealing the bottom and sides of the landfill called containment barriers. Natural clay are used for their construction. Fine-grained industrial waste of a mineral nature has been proposed as an alternative to them. Two-component mixtures of ash from solid fuel combustion and waste coal sludge have been developed. The basic expected property of an isolation barrier is its impermeability. Also important is the sorption capacity of the material from which the barrier is made. Hence, the purpose of the study was to evaluate the potential of the obtained mixtures to remove selected heavy metals and PAHs from aqueous solutions. The examinations of static batch sorption and sorption under flow conditions were conducted in columns. Solutions containing Zn(II), Cd(II), and Pb(II) ions with initial concentrations of 100, 200, and 500 mg L−1 were used in the experiment. For all mixtures, regardless of the initial concentration, batch sorption of metals exceeded 99%. In polymetallic solutions, the competitive phenomena between zinc and cadmium ions were confirmed, resulting in a decrease in the efficiency of their removal from the solution. The column tests carried out using raw leachate from a municipal landfill showed the effectiveness of the mixture in removing PAHs, particularly noticeable for di- and hexacyclic hydrocarbons. The removal rate of the 5 analyzed PAH groups ranged from 47.49 to 70.0%. The obtained results confirmed the high sorption capacity of the tested material, which allows considering its use as a sorbent in environmental engineering.

Application of cellulose nanocrystals in 3D printed alkali-activated cementitious composites

With the rapid development of concrete 3D printing for construction projects, it is crucial to produce sustainable 3D-printed cementitious composites that meet the required fresh and hardened properties. This study develops sustainable 3D-printed cementitious composites of ordinary portland cement and alkali-activated materials using cellulose nanocrystals (i.e., green natural nanomaterials). The extrudability and buildability of the alkali-activated slag-fly ash mixtures were improved and the extrusion pressure was reduced by ~ 35 % by increasing the cellulose nanocrystals content (up to 1 %) suggesting their viscosity-modifying properties in alkali-activated materials. The inclusion of cellulose nanocrystals improves the overall mechanical performance (8–20 % increase) and reduces the porosity of ordinary portland cement and heat-cured alkali-activated samples. Further, the addition of cellulose nanocrystals (up to 0.30 %) in sealed-cured alkali-activated samples improves their flexural strength by 20 %. The ordinary portland cement sample with cellulose nanocrystals densifies the microstructure and has an approximately 25 % increase in the degree of hydration at inner depths indicating cellulose nanocrystals' internal curing potential. The developed 3D-printable alkali-activated composites with cellulose nanocrystals can provide an overall reduction in the environmental impacts by eliminating/reducing the need for chemical admixtures to improve material consistency and stability, and replacing 100 % of portland cement.

Power generation potential of plant microbial fuel cells as a renewable energy source

The global energy demand has increased interest in the development of new technologies that offer alternative, cost-effective energy solutions with minimal environmental impact. Among these technologies, is microbial fuel cell (MFC), which takes advantage of the electrical energy produced through the metabolic reactions of microorganisms when they encounter a substrate. This study assesses the electric power generation potential of MFC configured using as a substrate and source comprising a mixture of soil, sand, organic fertilizer, and ash in a proportion of 3:2:1:1/2. Native plants (Torenia fournieri, Kalanchoe blossfeldiana, Pentas lanceolata, Nephrolepis exaltata, Begonia semperflorens, or Asplenium nidus) were planted to promote the exchange of organic chemical species and nutrients for renewable electrical energy generation. The configuration, constituting a system of fuel cells with microorganisms and plants (Plant Microbial Fuel Cell, PMFC), demonstrated varying whose efficiency levels, determined by measuring the potential between the cell electrodes. The highest voltage obtained in the PMFCs was 0.609 V for the Begonia semperflorens plan, while the lowest was 0.069 V for Asplenium nidus. Torenia fournieri and Asplenium nidus presented the highest voltage peaks at 1.782 and 1.587 V, respectively. Of the plants studied, Nephrolepis exaltata and Asplenium nidus were the only surviving plants after the measurements. When all were connected in series, excluding Asplenium nidus due to its instability, it resulted in an average voltage of 1.856 V. The minimum recorded voltage was 1.540 V, and the maximum electrical potential reached 2.050 V. Analysis of the soil samples, along with the substrate before and after the experiment, identified six electrogenic bacteria: Escherichia coli, Pseudomonas sp., Erwinia sp., Lactobacillus sp., Enterococcus sp., and Clostridium sp. The Escherichia coli was only present in the soil and substrate sample before the experiment, while the concentration of Pseudomonas sp. and Erwinia sp., increased. This study confirmed that PMFCs with low-cost substrates and native Caribbean plants, represent a promising technology that could drive energy development in developing countries, especially in remote areas lacking access to electricity. This implementation of PMFCs aligns with sustainable energy practices, offering a cost-effective strategy, that can be replicated globally, contributing to the achievement of Sustainable Development Goal 7: Ensure access to affordable, reliable, sustainable, and modern energy for all.

IMPACT OF LEGISLATIVE CHANGE ON THE CLASSIFICATION OF RAW MATERIALS AND BUILDING MATERIALS IN TERMS OF NATURAL RADIOACTIVITY

Natural radioactivity is present in the human environment to a greater or lesser extent, also in varioustypes of raw or building materials. Monitoring of the concentration of natural radioactive isotopesof potassium 40K, radium 226Ra and thorium 228Th or 232Th in samples of raw and/or constructionmaterials allows assessing the exposure of people to ionizing radiation emitted by these materials.Exceeding the limit value of the radioactive concentration index for raw and/or building materials,defined in the Ordinance of the Council of Ministers (Polish Journal of Laws/Dz.U. No. 33/2021),may result in an effective radiation dose greater than 1 mSv/year – the dose limit for the population.In Poland, pertinent legislation requiring the establishing of the natural radioactivity of raw and/orbuilding materials dates back to the 1970s and has been changed several times by now. However, themost significant changes in the legislation have occurred recently. Due to the obligation of imposingthe application of the provisions of the of European Council 2013/59/EURATOM of 5 December2013 laying down basic safety standards for protection against risks arising from exposure to theeffects of ionizing and repealing Directives 89/618/Euratom, 90/641/ Euratom, 96/29/Euratom,97/43/Euratom and 2003/122/Euratom (the so-called BSS version), it was necessary to adopt theamendment to the Atomic Law. The implementation of the BSS Directive in Poland was issued on thebasis of the resolution of the Parliament of June 13, 2019 amending the Atomic Law Act and the FireProtection Act (Polish Journal of Laws/Dz.U. 2019, item 1593). The amendment of the Atomic LawActs led to the harmonisation of regulations on radioactivity in raw and building materials betweenPoland and the Member States. This article presents the impact of an amendment of the AtomicLaw and of the accompanying normative acts on the studies of the natural radioactivity of raw andconstruction materials, using the example of an analysis of the concentration of natural radioactiveisotopes present in the coal combustion products (CCP), i.e. fly ash, slags and ash-slag mixtures.

Effect of curing strength in lime – coffee husk ash mixture on clay

Coffee husk is a fibrous material obtained from coffee beans. It is a waste from coffee industries. In order to reduce the disposal problem, utilization of waste in civil engineering works is very important. This study has been carried out to explore the utilization of coffee husk ash for improving properties of Kumarakom clay. Kumarakom clay is known to be very problematic in construction field. It is considered neither suitable for building houses nor for construction of roads. Coffee husk is a by-product of coffee roasting process. After removal of coffee beans, a huge amount of coffee husk is generated later, the ash obtained after burning of coffee husk i.e; Coffee Husk Ash (CHA) is used in this study. The Kumarakom clay can be stabilized with different percentages (5, 10, 15, 20, 25) of coffee husk ash and variation in strength can be determined by Unconfined Compression Strength (UCS) test and proctor compaction test. The optimum percentage is obtained at 20% of CHA addition. Finally, the curing strength test is conducted for varying percentages of CHA – clay mix and optimum percentage of CHA – lime mix for about 7, 14, and 28 days.

Mechanical strength and Life Cycle Assessment (LCA) of soil-cement: comparison between mixtures of soil with ASTM type III cement, LC3, and the incorporation of by products and agroindustrial residues

Soil stabilization with binders is based on the binder action on soil particles, in turn causing an improvement in the mechanical behavior of the soil. Thus, this study aims to analyze the mechanical and environmental properties of soil-cement mixtures using Portland ASTM type III cement as binders and comparing to LC3 (Limestone Calcined Clay Cement), as well as incorporating extra raw materials such as silica fume, fly ash, sugarcane bagasse ash (Saccharum officinarum L) and açai seed ash (Euterpe precatoria Martius). The mixtures of soil, binder, extra raw materials were performed manually, and the cylindrical specimens (100 mm internal ø) were molded based on the AASHTO Normal Test. The results showed that the highest values of compressive strength ranged between 10 and 11 MPa, which were recorded for reference, soil-LC³ and soil-LC-açai seed ash mixtures. Life Cycle Assessment (LCA) was performed using the CML 2001 method with the aid of the OpenLCA software. Additionally, it was observed that the main emissions and consequences for the environment were from mixtures containing higher clinker contents.

Quality of paving blocks soaking water made from medical waste incineration ash

Given the ash level of medical waste incineration utilized as a raw material mixture that contains metal compounds, dumping the paving block immersion water into rivers could result in a drop in water quality. The purpose of this study is to evaluate water quality during immersion of paving blocks made from medical waste incineration ash. Water quality was measured by five measurements in water before immersion, soaking for 7 days, 14 days, 21 days, and 28 days. The test method used is in accordance with SNI 6989-84:2019. The metal compounds examined in this study were Pb (lead), Copper (Cu), Nickel (Ni), and cadmium (Cd). Laboratory tests were conducted at the Jasa Tirta I Environmental Laboratory and the Sukoharjo Environmental Service. It can be concluded that there is no pollution due to heavy metals contained in paving blocks. The results show that the soaking water for 7 to 28 days is still below the specified quality, so paving block-making activities using a mixture of medical waste incineration ashes can be carried out. The need for other studies measuring the levels of other metals such as Cr, Hg, Sn, Ti, and Zn.

Composite Geopolymers Based on Mechanically Activated Fly Ash Blended with SrCO3 (Strontianite) and BaCO3 (Witherite)

In this study, geopolymers based on mechanically activated mixtures of fly ash (FA) with SrCO3 (strontianite) and BaCO3 (witherite) were synthesized. NaOH solution was used as an alkaline agent and curing was carried out under ambient conditions. XRD, FTIR spectroscopy, thermogravimetry, and SEM were used to study the geopolymerization process and microstructure. The product of geopolymerization of the milled (FA + SrCO3) and (FA + BaCO3) blends was X-ray amorphous N-A-S-H gel. The beneficial impact of mechanical activation on the compressive strength of geopolymers was most evident during the initial stages of the curing process. The strength of geopolymers based on the (FA + carbonate) blends after 7 d was either less than the corresponding strength of geopolymers based on the 100% FA or, within the measurement accuracy, equal to it. With increasing curing time, the strength development of geopolymers synthesized from (70% FA + 30% carbonate) blends exceeded the strength growth of geopolymers containing less carbonates; after curing for 180 d, these geopolymers showed the highest compressive strength (20–27 MPa). This trend was more pronounced for the geopolymers based on the (FA + SrCO3) blends. The influence of SrCO3 and BaCO3 addition to the FA on the strength of composite geopolymers was explained by dilution and microfiller effects. The geopolymers based on the FA blended with SrCO3 and BaCO3 exhibit potential applications in immobilizing radioactive strontium and producing radiation shielding materials.

Improving the rheological characteristics of fly ash water slurry using aqueous extract of Diascorea hispida

ABSTRACT Transportation of high-concentration slurry is a specialized field that requires a deep understanding of the rheological behavior of slurry. Fly ash, a fine, powdery residue of pulverized coal combustion in power plants, is transported in pipelines as a slurry with water as a carrier medium and flow-improver additives. The current research aims to compute the rheological properties of the fly ash-water slurry by adding 0.1 to 1 g/mL of Diascorea hispida extract as a natural drag reducer or flow improver. In addition to the effect of D. hispida, other parameters such as temperature, addition of fly ash, and fly ash-bottom ash mixture on the rheological performance of fly ash-water slurry have been investigated. The economic effect of the developed dispersant, D. hispida, has been examined by applying Darby – Melson combined equation by varying the slurry flow rate from 1 m/s to 3 m/s at a fixed 250 mm pipe diameter. The slurry head loss, solids conveying rate, hydraulic power need, and specific power consumption at different .D hispida concentrations were calculated.

The beneficial reuse of contaminated sediment: Long-term assessment of fly ash and lime-based mixtures

In recent decades, sediment has been recognised as a problematic resource due to its potentially harmful effects and the large quantities present in water bodies. There is a need to properly manage large quantities of dredged sediments so that they can be used as a resource and not necessarily treated as a waste product. This research investigates the effects of ageing and maturation of solidified/stabilized mixtures of contaminated sediment with fly ash and lime. The effects of ageing on the microstructural properties and chemical integrity of mixtures were studied for 7 days, 28 days, and 7 years using scanning electron microscopy and energy dispersive spectroscopy (SEM/EDS), X-ray diffraction analysis (XRD), and DIN (German Standard Procedure for Water, Wastewater and Sediment Testing (Group S)) and TCLP (Toxicity Characteristic Leaching Procedure) leaching tests. The results of the microstructure and strength analysis showed that the use of fly ash and lime as binders promoted the permanent structural integrity of the sediment. The treated sediment with 20 wt% fly ash and 10 wt% lime (F20L10) achieved higher overall strength compared to the mixture containing only 30 wt% fly ash (F30). The speciation and redistribution of metals and As in the treated sediment mixtures during the long-term evaluation indicate a strong reduction in their mobility. This material can be considered environmentally friendly and can be used as a fill material in road construction. The investment and operating costs are justified in this solution for sediment management. However, it is important to monitor the produced material over time to ensure that it remains effective and sustainable in the long term.
