“…The downturn test was utilized to check new substantial's functionality and decide the material's homogeneity. Three substantial 3D shape examples estimating 150 × 150 × 150 mm and three bar examples estimating 100 × 100 × 500 mm were projected and tried for compressive strength and flexural strength, separately, for each kind of cement in light of Indian Standard Particular IS:516-1959 [9]. The examples were cast and afterward set for 24 h at room temperature in the shape.…”

Concrete is the most frequently used material in development due to its high pliancy, economy, security, and outstanding durability. It must be sufficiently strong to endure various loads, with compressive strength being its most vital mechanical attribute. The current study investigates binary and ternary mixed concrete blends with silica fume, ceramic powder, bagasse ash, and alccofine to determine compressive and flexural strength. Results from compressive strength tests indicate that mixes containing superfine alccofine exhibit higher strength. Additionally, the impact of supplementary cementitious materials on surface morphology was examined using scanning electron microscopy. This study employs linear regression, K-Nearest Neighbors (KNN), and Bayesian-optimized extreme gradient boosting (BO-XGBoost) to estimate the compressive strength of ternary mixed concrete. The predictive models were validated using the coefficient of determination (R²), mean absolute error (MAE), and mean square error (MSE). Linear regression and BO-XGBoost models demonstrated high accuracy in predicting outcomes, with R² values of 0.883 and 0.880, respectively, compared to 0.736 for the KNN model. Furthermore, normalized feature importance analysis identified the input variables that significantly affect compressive strength, highlighting the importance of CaO and SiO₂ in predicting the compressive strength of ternary mixed concrete.

“…A study that replaced natural sand with WFS and bottom ash with a constant compaction factor of 0.78–0.83 found that increasing sand replacement with waste foundry sand and bottom ash increased water demand [ 53 ]. Reshma et al [ 52 ] reported that the compacting factor value of concrete lies in between 0.91 to 0.96 with partially substituting WFS [ 52 ]. Similarly, a study reported a compacting factor value of 0.90 to 0.94 [ 54 ].…”

Waste Foundry Sand in Concrete Production Instead of Natural River Sand: A Review

et al. 2022

The by-product of the foundry industry is waste foundry sand (WFS). The use of WFS in building materials will safeguard the ecosystem and environmental assets while also durable construction. The use of industrial waste in concrete offsets a shortage of environmental sources, solves the waste dumping trouble and provides another method of protecting the environment. Several researchers have investigated the suitability of WFS in concrete production instead of natural river sand in the last few decades to discover a way out of the trouble of WFS in the foundry region and accomplish its recycling in concrete production. However, a lack of knowledge about the progress of WFS in concrete production is observed and compressive review is required. The current paper examines several properties, such as the physical and chemical composition of WFS, fresh properties, mechanical and durability performance of concrete with partially substituting WFS. The findings from various studies show that replacing WFS up to 30% enhanced the durability and mechanical strength of concrete to some extent, but at the same time reduced the workability of fresh concrete as the replacement level of WFS increased. In addition, this review recommended pozzolanic material or fibre reinforcement in combination with WFS for future research.

“…As part of the global sustainability agenda to reduce carbon footprint and stay as environmentally friendly as possible, cement and sand replacement materials in concrete exist in various forms, such as blast furnace slag, which is a by-product of iron manufacturing used as a substitute for cement (Pal et al, 2003;Divsholi et al, 2014;Salvador et al, 2019;Ozbay et al, 2016;Mo et al, 2015). Fly ash, a fine powder, which is a by-product of burning pulverised coal in electric generation power plants, has been used to partially replace cement and sand in concrete (Christy & Tensing, 2010;Dhaka & Roy, 2015;Muhit et al, 2013;Jatio et al, 2019;Rajamane et al, 2007;Rafieizonooz et al, 2016;Reshma et al, 2021;Rajagopalan, 2019;Podolyakina, 2016;Białas, 2016). Copper tailings have also been used to partially replace sand and cement in concrete to reduce the depletion of natural resources (Muleya et al, 2020;Dandautiya & Singh, 2019;Kundu et al, 2016;Swetha et al, 2015).…”

Cement is an important construction material in concrete production; however, it is expensive and unaffordable for many low-income and rural communities in developing countries. Rice husk is a by-product from the rice mill process, with an approximate ratio of 200 kg rice husk per one tonne of rice produced. This experimental study aimed to investigate the integrity of concrete produced in Zambia using rice husk ash (RHA) to partially replace cement. The primary goal was to carry out a cost–benefit analysis on the use of RHA in concrete. RHA was used to partially replace cement with ratios of 10 %, 20 % and 30 %. The 20 % cement replacement mix produced the optimum 18 MPa concrete strength results at a 0.5 water/binder ratio. This translated in cost reduction of concrete by 12.5 %, which is particularly significant for higher concrete volumes. The produced concrete is suitable for lightly loaded structures, such as foundation footings, surface beds and walkways to benefit low-income communities. The study further concluded that the RHA based concrete was more cost-efficient in structures that were close to areas of rice production due to reduced RHA transportation costs.
