“…Then, the density of concrete gradually increased with an increase in cockle shell replacement for 20% (CS20) and 30% (CS30), with 2120 kg/m 3 and 2162 kg/m 3 , respectively. The results obtained were due to the fact that the specific gravity of cockle shell is in the range of 2.06-2.64 (Essalem & Cherradi, 2023), whereas the specific gravity for coarse aggregate is 2.71 (Essalem & Cherradi, 2023). As a result, concrete density consisting of up to 15% crush cockle shell is in the range of 2202-2228 kg/m 3 which is less dense than normal concrete density, which is in the range of 2200 -2500 kg/m 3 (Abbas et al, 2020;Ruslan et al, 2021).…”

Gravel is a natural raw material used in concrete mixtures. However, more of this scarce resource was used, which reduced the amount of gravel-based coarse aggregates that could be produced. As a result, efforts to preserve natural coarse aggregates for future generations were critical. So, an innovation to replace this natural coarse aggregate was required. The dumping of cockle shell waste by the cockle trade emits a stinking smell and pollutes the environment. This study investigates the density, compressive, splitting tensile and flexural strengths of concrete containing cockle shell as a coarse aggregate substitute. Four concrete mixes were prepared by integrating diverse contents of cockle shell as 0%, 10%, 20% and 30% partial replacement of coarse aggregates by weight of gravel. Concrete becomes less dense as a large amount of cockle shell is integrated. Utilization of cockle shell up to 10% enhances the compressive strength of concrete. However, increasing the amount of cockle shell by up to 30% can improve the splitting tensile and flexural strength of concrete

“…The absorption and porosity of a concrete at low percentages of replacement with seashell aggregate are less, when compared with conventional concrete, but these values are increasing with higher percentage of seashell replacement (Tayeh at al., 2019). However, experimentally was proven that decrease in mechanical properties of seashell concrete does not compromise the performance of the material for civil applications (Essalem and Cherradi, 2023). Some authors were studying the use of seashells as aggregate in cemented materials for masonry and plastering.…”

This paper explores the possibility of using recycled seashells from marine coasts of the Mali Ston Bay in Dubrovnik-Neretva County, Croatia, to create a novel bio material derived from waste seashells. In this research, two types of waste seashells, mussel (Mytilus galloprovincialis) and oyster (Ostrea edulis), combined with natural, non-toxic binders (bone glue) were investigated experimentally. The goal is to develop a sustainable material, suitable for the production of furniture and decorative objects. The parameters studied, included physical and mechanical properties of this material. The results showed that this bio composite material, derived from recycled seashells, is hygroscopic and has low compression strength. It should be used for making furniture components that don't bear heavy loads and it is suitable only for interior applications. This study presents an eco-friendly and sustainable material option, while optimizing the recycling of food waste materials.

Creating sustainable mortar containing recycled seashells is an innovative approach that can contribute to environmental conservation and reduce waste. The use of seashells as a partial replacement for traditional raw materials in mortar can have several benefits, including conservation of natural resources, waste reduction, and improved material properties. The current study uses Marsh Clam seashells after crushing the cleaned seashells into powder. Heated ( up to 600Co) and unheated seashells were considered in the experimental investigation. In both batches, a seashell powder (heated and unheated) was replaced with OPC cement in proportions of 6, 9 and 12% in the mixing process. XRD, SEM, EDS and mechanical tests were employed to determine the crystal structure and to provide a comprehensive understanding of the physical, chemical, and structural characteristics of the substance. The study concluded that the calcium carbonate (CaCO3) that is nature chemical form of seashells was turned to calcium oxide (CaO) during the heating process and the resulted product was highly reactive with water, improved microstructural properties of the concrete. It also promotes better particle packing, reduce porosity, and create a denser, more uniform concrete matrix and enhancing the overall performance of the material.
