The use of sugarcane bagasse ashes (sba) in the confection of concrete’s traces and precast, replacing and adding to cement

Concrete is one of the most used construction materials in the world, with cement being one of its main ingredients. The incorporation of Sugarcane Bagasse Ash (SBC) in the production of concrete can present solutions for the use of this agro-industrial by-product and minimize environmental impacts arising from the removal of limestone in the production of cement, in addition to contributing to the reduction of emission of carbon dioxide and preserve natural deposits for cement production. This study aimed to use sugarcane bagasse ash in the addition and partial replacement of cement in the production of concrete. The specimens (TBs) were manufactured following the NBRs 7223 and 5738, in which a ratio was adopted: (1:1.98:3.23:0.61) as primary proposal (T1), and the replacement (T2) and addition (T3) of 5% of Portland cement by mass was performed. The ruptures of the specimens were performed by the compressive strength test of concrete cylindrical specimens at 7, 14, 21 and 28 days of age, after rectification. The results obtained show that it is feasible to use SBA, since the water/cement ratio and the percentage of mass to be replaced or added are appropriate, because both in the addition and the replacement of 5% cement by SBA obtained a gain in strength of concrete.

INCORPORATING OF WASTE FROM SUGAR INDUSTRY AND CEMENT INDUSTRY IN CONCRETE

<p>As the production of biomass waste from agroindustry grows across the world, a large amount of agro-based ashes ends up in polluting land. India produced 405.4 million tones of sugarcane in 2019, with a capacity of 105.4 million tonnes of bagasse and 2.5 million tonnes of SBA. The utilization of such ashes as SCMs contributes to a fixing of issues related to CO2 emissions from cement industry and land pollution in agro-based industry. Although many research has been performed on the utilization of Sugarcane Bagasse Ash (SBA) and limestone in concrete, research on their combined usage in the concrete is limited. As a result, the current work involves the performance evaluation of a ternary blended concrete incorporating SBA and limestone. The blended concrete's workability properties, compressive strength, water absorption, RCPT, Sorptivity, water permeability and electrical resistivity are examined in this paper. It was observed that a minimum of 10-15% limestone along with 10% SBA was adequate to increase the concrete performance, however exceeding 15 percent had a detrimental impact on concrete properties. In summary, utilization of SBA and limestone powder reduces cement consumption, reduce environmental impact due to SBA and cement, improves the economy, and increases the sustainability of concrete production. It improves the compressive strength and durability properties of ternary blended concrete.</p>

Investigating the influence of sugarcane bagasse ash volume variation in glass fiber reinforced with epoxy resin matrix composite material

Composites were manufactured from glass fiber, bagasse fly ash, and epoxy matrix and examined their mechanical and physical properties. The percentages of bagasse fine ash, glass fiber, and matrix were designed at 10%, 15%, 20%, 25%, and 30% with 30% glass fiber and conducted density, flexural strength, hardness, absorption of water, and swelling properties of thickness. Composites were prepared by manual layering. ASTM standards were followed in preparing the samples. According to the results, the bagasse fine ash percentage variation was significant in the composite but had no linear effects on its hardness and flexural strength. A 20% bagasse fine ash composite had the highest flexural strength and hardness at 27.65 MPa and 52.86 HRA, respectively, which are significantly (>0.002) higher than composites of 30% bagasse fine ash, along with the highest density. This study measured water absorption and swelling of composite samples immersed in distilled water for 192 h. As the bagasse ash content increases, these values were linearly increased until saturation occurs.

Sugarcane-bagasse-ash in enhanced mesophilic Co-digestion for biogas and nutrient recovery: A concept of developing rural circular bioeconomy

Conductive agro-industrial wastes as accelerants in the anaerobic digestion (AD) of organic waste is a good technique for developing a rural circular economy, such as producing bioenergy and biofertilizer. This study disclosed the a role of sugar cane bagasse ash (SCBA) in enhancing the bioenergy (biogas) yield and digestate fertility via anaerobic co-digestion (AcoD) of buffalo dung (BD) and vegetable residue (VR) under mesophilic conditions (37 ᴼC). Firstly, an optimal BD/VR ratio (1:3) was determined based on biogas yield by introducing five different BD/VR ratios (1:0, 3:1, 1:1, 1:3, and 0:1) into AcoD systems. Secondly, the biogas yield was increased further by adding SCBA at five different concentrations (0, 0.5, 1, 1.5, and 2 wt%). Experimental results disclosed that the 1.5 wt% of SCBA gave the highest cumulative biogas yield (153.67 mL/g VS), COD removal rate (31.18%), and fertility (5.08%). Moreover, a framework is suggested to understand the role of SCBA in the enhanced DIET mechanism. This work documents an environmentally friendly and economical technique for developing a rural circular bioeconomy via the AD of organic agro-waste.

An Evaluation of the Performance of Lateritic Soil Stabilized with Cement and Biochars to be Used in Road Bases of Low-Volume Sealed Roads

The study investigated the effects of adding Saw Dust Ash (SDA) and Sugar Cane Bagasse Ash (SCBA) on the strength of cement with stabilized lateritic soil. The experiments carried out in both the lateritic soil and stabilized lateritic soil considered Atterberg limits, sieve/hydrometer analysis, compaction, soaked California Bearing Ratio (CBR), and Unconfined Compressive Strength (UCS) at various curing periods. Ordinary Portland Cement (OPC) was introduced into the soil with varying content (0%, 3%, 5%, 7%, and 9%) by weight of the soil sample. The results showed that CBR and UCS increased to 175.7% and 1.999 MPa, respectively, as the OPC content increased to 7%. The optimal OPC content to meet the 1.5MPa UCS requirement for road bases on low-volume sealed roads in Kenya was 7%. The next treatment involved partially replacing the OPC content with SDA and SCBA in different doses (7-0-0%, 5-1-1%, 3-2-2%, 1-3-3%, and 0-3.5-3.5%, respectively) for various curing periods. The results showed that CBR and UCS decreased as the OPC content decreased and SCBA and SDA increased. At a content of 5% OPC, 1% SDA, and 1% SCBA, UCS and CBR were 1.877 MPa and 149%, respectively, suggesting that it was the optimal dosage to meet the 1.5MPa UCS requirement for road bases on low-volume sealed roads in Kenya. The durability test indicated that the specimens treated with 5% OPC, 1% SDA, and 1% SCBA met the 80% durability index mark, as recommended for cement-stabilized soils. Previous studies used SDA and SCBA separately with cement or lime to stabilize the subgrade or subbase of roads, but this study focused on using these materials together as a partial OPC replacement to stabilize lateritic road bases for use in low-volume sealed roads. The goal was to use local agricultural and industrial waste materials in road construction and improve the strength characteristics of road bases while preserving the environment through waste utilization.

Mechanical and Structural Correlation of Lateritic Soil Road Base Stabilized with Cement and Selected Biochars

The study considers the strength and structural characterization of lateritic soil road base in order to increase the strength of low-volume sealed road construction. Sugar Cane Bagasse Ash (SCBA) and Saw Dust Ash (SDA), mixed with soil and in combination with different percentages of Ordinary Portland Cement (OPC), were utilized in the current study. Structural and mechanical characterization of the investigated samples was performed by X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), Standard Proctor Test (SPT), Unconfined Compression Strength (UCS) Test, and California Bearing Ratio (CBR) Test. The observed increase in strength may be due to the reduction of mica, quartz, and calcite in the investigated samples. CaO and SiO2 contribute to the development of strength in cement, while SCBA, and SDA-stabilized lateritic soils. The microstructural study revealed that the mica, quartz, and calcite phases play a very important role in maintaining the strength and stability of the investigated samples.

Experimental study on stabilization of clayey soil using agricultural and industrial waste

The purpose of this experimental study is intended to explore if SCBA (Sugarcane Bagasse Ash and Marble Dust) may help clayey soil stabilize and hence to overcome environmental pollution. BA (Bagasse Ash) is the waste produced by the sugar factory after the processing of sugarcane. Factories dispose of the BA in the landfills which affect the environment, one of the reasons to do this experiment is to make use of this waste product for a sustainable environment. At the time of marble manufacturing, marble dust is produced. The soil around a building's foundation plays an important influence on its stability. As a result, the engineer should have a complete understanding of the components that influence soil behaviour and can be affected by the soil stabilization process. The soil is treated with bagasse ash and a partial replacement of marble dust (13 percent, 17 percent, and 21 percent) (10 percent, 12 percent, and 14 percent). In this study, a large number of specimens were made, and then the test specimens were analyzed for compaction characteristics and CBR. It was discovered that an increase in MD (Marble Dust) and BA increased the compaction and CBR characteristics to a certain extent.

Performance of agro-wastes and chemical admixtures used in concrete: A review

Concrete is an artificial composite material made up of four main components: cement, fine aggregates, coarse aggregates, and water. Because of its adaptability, durability, and economic issues, it has rapidly gained popularity as a construction material around the globe. The manufacturing process of cement leads to the release of significant quantities of the greenhouse gas carbon dioxide. Finding alternatives to cement and natural aggregates is becoming more necessary and important.The ash that is produced when agricultural waste is burned as a fuel presents a few problems, such as the contamination of the soil, but it also has the potential to be used as a cement substitutebecause of its pozzolanic qualities. This research paper explores the utilization of agro-waste ashes, including Corn cob ash (CCA), Rice husk ash (RHA), Palm oil fuel ash (POFA), wood waste ash (WWA), bamboo leaf ash (BLA), Coconut husk ash (CHA), Groundnut shell ash (GSA), and sugarcane bagasse ash (SCBA), as substitutes for cement in concrete mixtures. Additionally, it delves into a comprehensive examination of various chemical admixtures such as water reducing, corrosion inhibiting, shrinkage reducing which are commonly employed to improve concrete performance. The use of agricultural waste in cement and concrete could lead to a range of benefits which include reduced CO2 emissions, improved strength and durability properties of concrete resulting lower the production costs of concrete. Chemical admixtures help to attain stronger and durable concrete.

Sugarcane bagasse ash—The future composite material: A literature review

Cement is considered an irreplaceable and unique concrete building material that is in high demand worldwide. Burning fossil fuels and using electricity to make cement produce carbon dioxide, which contributes to greenhouse gas emissions. To reduce CO2 emissions, we need to use less cement in concrete. Agricultural wastes such as sugar cane bagasse, rice husks, and palm oil play an important role in reducing the CO2 emissions of concrete by substituting some of the cement. Treatment of sugarcane bagasse ash collected from scrap mills by washing and incineration changes the morphological properties of bagasse ash, making it suitable as a pozzolanic admixture. It is clear that sugarcane bagasse ash replacement cements exhibit favorable processability, improved concrete mechanical properties (compressive strength, flexural strength, splitting strength), reduced permeability, resistance to thermal activation, and electrical conductivity.

Investigating The Combined Effects of Replacing Cement with Sugarcane Bagasse Ash and Coarse Aggregate with Ceramic Tile Waste in Concrete Production

In pursuit of sustainable and innovative construction practices, this study investigates the combined effects of sugarcane bagasse ash (SCBA) and ceramic tile waste (CTW) as subsititue to aggregates on concrete properties, aiming to optimize their usage as eco-friendly alternatives. However, SCBA is a waste product of sugar industry. As a result of increasing recognition and understanding of sustainability and recycling in academia and industry over the past several decades, sustainability and recycling have become increasingly significant. It is also important to note that recycling construction waste and debris is one of the opportunities available for reducing construction waste. To optimize the amount of cement replaced by SCBA, the cement was partially replaced by SCBA and the ceramic waste was replaced at different dosages of 10%, 20%, and 30% by weight of coarse aggregates. Different properties such as workability and compressive strength have been evaluated during 7 and 28 days following replacement by SCBA and CTW. The results further revealed that the workability decreased with the inclusion of SCBA and CTW due to water absorption by the CTW and SCBA particles. However, the compressive strength of concrete mix was relatively higher at 10% replacement of cement by SCBA and 10% replacement of CTW, after which it decreased beyond 10% replacement. The maximum compressive strength was observed as 29.31 MPa with 10% SCBA and 10% CTW at the age of 28 days which is around 9.7% higher than the control mix concrete. It was deduced from the results of this study that 10% SCBA and 10% CTW replacement by the cement and coarse aggregates respectively, could be considered asoptimum replacement.

Study on Durability Properties of Ternary Concrete Containing Agriculture Waste and Limestone

Abstract: This study focuses on exploring the potential of sugarcane bagasse ash (SBA) as a sustainable additive in concrete to enhance its durability properties for construction applications. The research investigated five different concrete mixes, including control, binary, and ternary cementitious systems. The binary mix incorporated 10% SBA, while the ternary system combined 10% SBA with varying proportions of limestone (10%, 15%, and 20%) as a partial substitute for Ordinary Portland cement (OPC). The durability properties of the concrete mixes, including acid resistance, sulphate resistance, sorptivity, water absorption, water impermeability, and porosity, were thoroughly evaluated. Based on the experimental results, the optimal mix proportion was identified as 10% SBA + 15% limestone, with the remaining 75% comprising OPC. The findings demonstrated that this specific combination of materials significantly improved the durability of the concrete, indicating the potential of SBA as an eco-friendly and effective solution for sustainable construction practices.

Impact of Sugarcane Bagasse Ash (SCBA) and Cement to the Strength Improvement of Hemic Peat

Peat soils are derived from organic deposition consisting of dead trees. Peat soils have low shear strength and cannot afford large loads. Various treatment methods are used to stabilize peat soils and most of them use cement as a main binder to increase the strength of peat soils. However, the use of large quantities of cement is not environment friendly due to the release of carbon dioxide (CO2) and wastage of energy consumption by the cement production industry. Therefore, the introduction of SCBA as a substitution binder for some cement dosage is good as well as reducing the degradation of dumping waste which is increasingly uncontrollable. The objective of this study is to identify the basic and physical properties of peat soil from Pontian, Johor. In addition, this study was also conducted to identify the impact of SCBA on peat soil stabilization with cement. There are 5 different mixtures for cement and SCBA which are C100, C95S5, C90S10, C85S15 and C80S20 used in this study. Sample C95S5 with mixtures 95% cement and 5% SCBA were the optimum samples for this study based on unconfined compression strength (UCS) tests. The C95S5 sample successfully achieved the maximum strength of the whole sample with a strength of 190 kN/m2, 209 kN/m2, and 219 kN/m2 recorded for wet curing periods of 7,14 and 28 days. Therefore, the use of SCBA materials in the stabilization of peat soils with cement and calcium chloride (CaCl2) is seen to have a positive effect in increasing the shear strength of Hemic peat soil samples.

Silica aerogel from sugarcane bagasse ash incorporated cementitious thermal insulation composites

Silica aerogel was synthesized from sodium silicate solution extracted from sugarcane bagasse ash by sol-gel processing and solvent exchange. The effects of processing parameters, especially the volumetric ratio of trimethylchlorosilane (TMCS) to n-Hexane used to modify the surface of the silica aerogel, were studied. The results showed that the optimal silica concentration to synthesize silica aerogel was 1.0 mol/l with a volumetric ratio of TMCS to n-hexane of 7:50. Silica aerogel synthesized by sodium silicate solution extracted from sugarcane bagasse ash produced a surface area, pore volume, and pore radius of 822 m2/g, 2.69 cm3/g, and 1.70 nm, respectively. Towards development of insulating material, the effects of silica aerogel addition on the microstructure, mechanical properties and thermal conductivity of cement composite were investigated. The results also suggest that the addition of the silica aerogel resulted in a relatively low thermal conductivity of the cement composite of 0.42 W/m∙K.

Achieving strength and sustainability in ternary blended Concrete: Leveraging industrial and agricultural By-Products with controlled Nano-SiO2 content

High-performance ternary mixed nano-concrete has been extensively utilized in high-rise structures due to its desirable strength, durability, and thermal insulation ability. Additionally, nano-concrete usage is the most current area of research in concrete components. This research investigates the compressive strength, flexural behavior, and micro-structure behavior of nano-SiO2 concrete specimens. This study also evaluates the strength development of mixes combining binary and ternary combinations of agricultural by-products (rice husk ash, corncob ash, and bagasse ash) and industrial by-products (fly ash, ground granulated blast furnace slag, and metakaolin). The cost-efficiency, energy-efficiency, and eco-efficiency of ternary blended nano-concrete with various additives were considered when evaluating their sustainability capabilities. This study aims to improve sustainable high-performance concrete without overutilizing or underutilizing additives. Based on the findings, nano-SiO2 concrete can achieve greater compressive strength ranges of 51 to 70 MPa with binary and ternary admixtures. Furthermore, ternary nano-SiO2 concrete performs more sustainably than other mixes regarding cost-effectiveness, energy use, and CO2 emissions, as do mixes made of sugarcane bagasse ash and ground granulated blast furnace slag.

Acoustics of Compressed Earth Blocks Bound Using Sugarcane Bagasse Ash and Water Hyacinth Ash

Mechanical compaction is often used to densify building earth blocks by reducing the void between the particles. Compacted stabilised earth involves a binder, which holds the particles of the materials together. The compaction and addition of binders to the earth can modify its transport, mechanical, and acoustical properties. In this study, the acoustic transmission coefficient, porosity, and airflow resistivity were investigated by varying the concentrations of water hyacinth ash (WHA) and sugarcane bagasse ash (SBA) binders. An acoustic test rig comprising an acoustic wave guide made from joined water pipes was employed to analyse the influence of the WHA and SBA binders on the acoustical performance of the earth blocks. It was found out that the measured acoustic wave transmission was sensitive to the variation in the composition of WHA and SBA in the earth blocks. Increasing the WHA concentration led to an increase in the acoustic transmission coefficient and porosity, but reduced the airflow resistivity of the compressed earth blocks; while increasing the SBA reduced the transmission coefficient and porosity, but increased the airflow resistivity. This shows that SBA has a stronger binding property than WHA, which is ideal for the manufacture of stronger earth blocks, while the higher porosity of the earth blocks obtained with WHA is good for the construction of porous walls, which is good for maintaining the airflow between the inside of buildings and the surrounding.

Electrochemical study on the chloride corrosion susceptibility of cementitious composites produced with sugarcane bagasse ash sand

Sugarcane bagasse ash sand (SBAS) has been studied as a potential additive for reinforcement structures, but long-term (more than a week) studies on its use in test specimens have not been conducted considering the durability of these concretes. Additionally, there has been no assessment of electrochemical corrosion in corrosive media, such as chloride solutions. In this study, we conducted a physical and electrochemical investigation of SBAS, which partially replaces fine sand in a mortar configuration. Electrochemical impedance spectroscopy and open circuit potential monitoring techniques were used to evaluate the reinforcements in Ca(OH)2 (curing environment) and NaCl 3.5% (aggressive environment), and SEM-EDS was used to analyze the reinforcement surface. During the curing process, SBAS concrete formed a passivation film after a longer time (7–14 days) than the reference (REF) (7 days), and the passive film showed higher resistance values than the REF sample. After 191 days in the chloride medium, REF and SBAS samples presented similar corrosion resistance. Therefore, SBAS-reinforced concrete could be a sustainable and effective alternative to conventional concrete for structural applications.

Sugarcane bagasse ash as a partial replacement for cement in paste and mortar formulation – A case in the Philippines

The quality of sugarcane bagasse ash (SCBA) varies significantly from one locality to another. It greatly influences its performance when used as cement replacement, thus requiring actual empirical data to be generated. This research explored the potential of locally available SCBA in the Philippines as a partial cement replacement material and assessed the appropriate formulations of the paste component with SCBA as part of the cement to be used for mortar and concrete production in the future. Mixtures with different SCBA-to-binder ratios (SBR) up to 20%, and water-to-binder ratios (WBR), were formulated to determine their effects on the consistency and setting time of paste, consistency of fresh mortar, density, and compressive strength of hardened mortar. Multivariate regression analysis was adopted to better interpret the influence of SBR and WBR on the different responses and generate models for their subsequent prediction, including the water requirement, to achieve normal consistency. It was found that increasing SBR from 0.00 to 0.20 increased the water demand for the paste from 0.27 to 0.36 WBR. An increase in the WBR subsequently increases the initial setting time to as much as 198 ± 16 min and the final setting time to 288 ± 4 min. The water demand for mortars also increased with increasing SBR to achieve the same workability. Generally, the models generated enabled good predictability (≥90% accuracy) of the water requirements of both paste and mortar. The density and compressive strength of mortars improved with SBR at 0.05 but then decreased as the SBR was increased. However, mixtures with SBR at 0.10 reached a compressive strength comparable to mixtures with pure cement, rendering the maximum amount that the cement can be replaced at 10%.

Mechanical properties and life cycle assessment of sugarcane bagasse and corn cob ashes‐based geopolymer concrete to promote circular economy

AbstractGeopolymer concrete (GC) has emerged as an environmentally friendly alternative to ordinary concrete, resulting from the alkalination of an Alumino‐Silicate (Al‐Si) source material. Large‐scale applications of GC are predicated on a suitable supply of Al‐Si sources, however rapid depletion of traditional sources like fly ash imposes a challenge therein and alternative source materials need to be identified. Agricultural waste ashes (AGWA) also exhibit high Al‐Si content; therefore, in this study, two AGWA, that is, Corn Cob Ash (CCA) and Sugarcane Bagasse Ash (SCBA) were used in lieu of fly ash for GC synthesis. The results for workability and mechanical testing showed that properties of GC remained intact for up to 20% and 10% CCA and SCBA, respectively. Life cycle assessment showed that AGWA‐based GC reduced the greenhouse gas emissions of ordinary concrete by 49% and can be used as an environmentally friendly alternative thereof, thus contributing to the circular economy.

A novel TOPSIS linear programming model based on response surface methodology for determining optimal mixture proportions of lightweight concrete blocks containing sugarcane bagasse ash

The idea of utilizing waste from the agro-industrial sector to produce lightweight concrete is one of the good ideas for recycling and reusing waste materials. In a lightweight concrete production process, determining a material's optimal parameters is crucial, since it can help optimize the important properties of lightweight concrete blocks. This study introduces a novel TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) linear programming model, based on the Response Surface Methodology (RSM), to optimize the parameters of lightweight concrete blocks. The compressive strength, dry density, and water absorption are considered important responses, while black bagasse ash, cement with white bagasse ash, and aluminum powder are the factors considered. The proposed method successfully optimized the parameters, as confirmed by experimental results, showing a 7.22% increase in compressive strength, a 9.19% increase in dry density, and a 16.83% decrease in water absorption compared to the original condition. These improvements were achieved by using the optimal mixture ratio of 6:1:0.05 by weight, which consists of sugarcane bagasse ash, cement, and aluminum powder. The advantages of the proposed method are as follows: This paper presents a novel method called the TOPSIS linear programming model, which is a modified version of the original TOPSIS method, to calculate the closeness efficiency for each run. The proposed method is simpler and more practical, making it useful for solving multi-response optimization problems with large inputs. In addition, this research contributes to the advancement of sustainable materials and offers a practical solution for optimizing lightweight concrete block properties.
