“…Weight loss in an alkaline environment reduced from 3.13% to 2.4% in 10-15% RHA content. Swaminathan et al [22] investigated the influence of a ternary mix of Portland cement, metakaolin, and RHA on the durability properties of an M60 grade HPC. Their results revealed that the durability dimensions of water absorption, sorptivity, porosity, and permeability penetration improved due to RHA's presence in the mixture.…”

The present study examines the durability properties of Class 1 (50–75 MPa) high-performance concrete (HPC) blended with rice husk ash (RHA) as a partial replacement of CEM II B-L, 42.5 N. Six HPC mixes were prepared with RHA and used as 5%, 10%, 15%, 20%, 25%, and 30% of CEM II alone and properties are compared with control mix having only CEM II. The binders (CEM II and RHA) were investigated for particle size distribution (PSD), specific surface area (SSA), oxide compositions, mineralogical phases, morphology, and functional groups using advanced techniques of laser PSD, Brunauer–Emmett–Teller (BET), X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared/attenuated total reflection (FTIR/ATR), respectively, to understand their import on HPC. Durability properties, including water absorption, sorptivity, and chemical attack of the HPC samples, were investigated to realise the effect of RHA on the HPC matrix. The findings revealed that the durability properties of RHA-based HPCs exhibited an acceptable range of values consistent with relevant standards. The findings established that self-produced RHA would be beneficial as a cement replacement in HPC. As the RHA is a cost-effective agro-waste, a scalable product of RHA would be a resource for sustainable technology.

The burned clay brick industry produces approximately 360 billion bricks per year, causing major land degradation and unprocessed pollutants. The quantity of bricks necessitates the use of 15,500 hectares of land. The topsoil necessary to produce traditional brick is 2200 m3 / billion bricks per year, whereas only 0.75 hectare of surface of land is needed to produce millions of clayey bricks each year. Another aspect of environmental degradation was its inefficient use of fly ash, which would be created by thermal power stations (TPS). Around 120 million tonnes of fly ash were produced yearly in India through 260 million tonnes of coal (65 percent of India's annual coal production), covering nearly 15,000 hectares of useable land. Apart from fly ash, a variety of materials, such as clay, silica fume, and bottom ash, could be used as pozzolanic materials which react with both the alkaline activator. The influence of chemical activators, their proportioning, curing conditions, and curing time all impact the strength properties for geopolymer materials. As a result, geopolymer development has a wide range of applications. Compressive strength, water absorption, and sulphate attack were all measured on geopolymer concrete mixes. The objective of this investigation findings was compared to the fly ash based geopolymer concrete block made of natural aggregate with different replacement levels of fine aggregate as natural sand, manufactured sand and Ecosand with required mix proportion are all within the IS 15658 guidelines.

Infrastructure development is rapidly increasing, driving up demand for concrete, a key construction material. Cement and aggregate are essential constituents, with global cement production reaching 4.1 billion metric tons in 2011 and CO2 emissions hitting 1.7 billion metric tons by 2024, a significant contributor to carbon emissions. To address this, alternative constituents like Rice Husk Ash (RHA) and Animal Bone Powder (ABP) are proposed. With rice husk comprising 20% of rice weight and a substantial cattle population in Bangladesh, RHA and ABP offer promising alternatives. This study examines the benefits and limitations of incorporating RHA and ABP into cement, focusing on concrete strength and permeability. By replacing varying percentages of cement with RHA and ABP simultaneously, experiments evaluate their impact on concrete properties after 28 days of curing. The research aims to identify the optimal combination for sustainable concrete production, reducing environmental impact by curbing waste generation and pollution. Results show that compressive strength increases and permeability decreases with up to 5% replacement of RHA and ABP, highlighting their potential for enhancing concrete performance while mitigating environmental concerns.
