“…When compared to Control 1 specimen, series with 100% CBA (10GCBA-100CBA) lowers by around 51%, yet it still maintains an adequate structural strength value. The strength values corresponded to those reported by Bheel et al [21] at 28 days age of curing. Futher reduction in compressive strength versus coal bottom ash content in seawater-mixed concrete containing ground coal bottom ash are shown in Fig.…”

An experimental studywas carried out tostudy the properties of concrete madewith seawater as total mixing water, ground coal bottom ash as binary cement and coal bottom ashas sand replacement.The first stage mixes were prepared with three percentages (0, 10, 20 and 30) of ground coal bottomash as partial replacement of binder.The second stage mixes involved10 percent of ground coal bottom ash with 25%,50%, 75% and 100% of coal bottom ash replacing naturalsand. Properties investigated were materials properties,binderchemical composition,concretehardened density,compressivestrength,and SEM. Test on hardened density was conductedon 7 and 28 days. Ground coal bottomash was identified as Class F, while coal bottom ash has lowspecific density and high-waterabsorption compared to naturalsand.Concrete density andcompressive strength decreased on use of coal bottom ash as fine aggregate. Compressive strength was seen to decrease as CBA percentagerose, with the maximum value being 44.4 MPa for combination of 10 percent ground coal bottom ash and 25 percent coal bottom ash.Series with 10% CBA (ground coal bottom ash) reduces by roughly 51% while maintaining a sufficient structural strength value.The findings of this investigation showed that it is possible to produce seawater-concrete, which incorporates coal ashin concrete.

Nowadays, researchers have been on the lookout for eco-sustainable additives such as agro/industrial waste in concrete in order to offset the carbon footprint created by cement manufacturing. However, it has been said that the use of agro/industrial-waste-based cementitious materials in concrete improves its quality. However, this study compared the performance of hydrated lime and cement concrete replaced with 5% and 10% Costus englerianus bagasse ash and bagasse fibre for determining the mechanical properties (compressive and flexural strength). Moreover, compressive strength was evaluated on cubical specimens and flexural strength was evaluated on beam samples at 7, 14, and 28 days, respectively. Results showed that the compressive strength and flexural strength of the concretes increased with an increase in the curing age. Also, the compressive and flexural strengths of cement concrete were recorded by 65.38 MPa and 10.86 MPa at 0% bagasse ash or fibre, which performed better than concrete replaced with 5% and 10% bagasse ash and fibre at 28 days, respectively. Besides, the compressive strength of concrete was noted by 53.85 MPa and 48.92 MPa at 10% bagasse ash and 10% bagasse fibre, respectively, while the flexural strength was calculated by 6.86 MPa and 5.54 MPa at 10% bagasse ash and 10% bagasse fibre, respectively, which were higher than that of concrete produced with hydrated lime alone at 28 days. Thus, bagasse ash performed better than bagasse fibre ash as a partial replacement of cement or hydrated lime in concrete production. Therefore, Costus englerianus bagasse ash or bagasse fibre improved the performance of hydrated lime concrete at 5–10% replacement, but higher concrete strength would be obtained in cement replacement than hydrated lime.

Concrete production requires a wealth of resources, including cement, aggregate, and water. Therefore, in terms of maintaining the Earth’s natural ecosystems and resources, researchers need to find sustainable and green methods for producing concrete. The focus of the current research was the use of potentially harmful alternative aggregates to manufacture lightweight concrete bricks. In this study, cement, fine aggregates, and vermiculite were the concrete brick mix components. Three trail mixes were followed by a replacement ratio of 60:40, 50:50, and 40:60 for fine aggregates in bricks. Statistical techniques were exerted to compare all the experimental results. Initially, regression analysis was employed to determine the precise relationship between the dependent and independent variables of the study. Furthermore, the compressive strength of the concrete brick was investigated. As a result of the research, vermiculite concrete bricks with the compressive strengths ranging from 3.2 to 5.9 kN/mm2 and densities ranging from 1,780 to 2,142 kg/m3 were obtained. The regression model captured the variability of the data, as evidenced by the suitable R2 threshold (R2 > 0.9935). Subsequently, every property of the concrete bricks was predicted using regression, surface plots, main plots, and a heatmap. The conclusion of the study demonstrated that the models generated very effective results.
