“…Yousheng et al [36] conducted a review and provided an account of the impact on both the mechanical and physical properties of concrete when crop residues like coconut husk, corn, bagasse, and rice are used as replacements for coarse and fine aggregates or cementitious materials in concrete production. Bhoj et al [37] investigated the utilization of CS as a substitute for coarse aggregates in concrete.…”

Due to urbanization, demand for concrete has been increasing up to 10 million cubic meter per year. Therefore, there is an urgent need to reduce the requirement for ingredients such as cement, sand, and aggregate. Cement serves as a binding material in concrete, which is being used in the construction industry since ancient times [1,2]. The admixtures are added in order to reduce the demand and supply gaps for cement, and the most common admixture is coal ash (CA) obtained from thermal power stations.

“…However, research has revealed that the ongoing use of river sand as a raw material for the creation of composite materials for buildings like sandcrete blocks, mortar, and concrete greatly adds to the depletion of natural resources, leading to flooding and the erosion of coastal regions [8] The possibility of using both treated and untreated coconut husk in place of some of the fine aggregates in masonry blocks was investigated by [9]. [10] reported that periwinkle shells are one such example of a marine waste product that can be used as a substitute, viable resource to substitute raw materials in order to limit difficulties with land-filling generated wastes and reduce pollution and manufacturing expenses. In nearly every Local Government Area in Nigeria, block production is carried out on a small-or large-scale industrial basis.…”

Animal bone waste (ABW) is hazardous to the environment and necessitates a sizable area for disposal. This study aims to employ animal bone waste (ABW) in functionalised compact concrete as a partial substitution for cementitious materials, the source of which are both unswerving and appropriate for substitute preventive solutions promotes the industry’s ecological sustainability by minimizing and reducing the negative impact of the concrete industry due to the explosive usage of raw materials. As a result, this paper examines the impact of using crushed animal bones as coarse aggregates in place of sand and cement in the production of concrete. With an improved step level of 10% through cement mass, ABW was applied at a percentage range of 0 to 40%. Bone’s various characteristics in its fresh and hardened states were looked examined. A Sieve shaker machine was employed to sieve the bone after which the bone was boiled and dried to remove moisture. To evaluate whether the employed aggregates and crushed animal bone were suitable for use in concrete, a physical analysis of each was performed.

The availability of agricultural wastes, especially corn stalks, offers sustainability benefits in reducing the demand for cement production. Altering this waste into ash becomes significant for cementitious material. Thus, the study utilized corn stalk ash (CSA) as a partially cementitious material in producing cement mortar. This experimental study aims to understand the compressive strength of CSA mortar samples and their characteristics, such as absorption and their correlation. Compressive strength and absorption tests were performed in the laboratory to specimen control (M0) and partial replacement of CSA to Portland Composite Cement (PCC) at different portions of 5%, 10%, and 15% or M5, M10, and M15 at 7d, 28d, and 56d. Before mixing, we measured cement and fine aggregate (sand) properties with a water-to-binder ratio (w/b) of 0.48, based on the standard reference in producing an ordinary mix mortar. The CSA used came from an agricultural field around central Java known to have good pozzolanic reactivity. Then, the average compressive strength and weight change were measured. The results indicate that the optimum increase in compressive strength of mortar was achieved with a 10 percent CSA replacement, which exhibited 96% enhancement from 7 to 28 days compared to other mixes. In addition, the weight changes of the mortar mix have shown an increase with the CSA replacement through 10 percent at 28 days of curing. Nevertheless, the relation between compressive strength and weight change of specimens shows a low linear relationship.
