“…Consequently, the greater water evaporation caused a greater shrinkage of mortar. Ruslan et al [ 45 ] investigated the mass loss of seashell mortar when exposed to different temperatures. The results showed that the mass loss increased with increasing exposure temperature and seashell content.…”

“…Secondly, the cleaned, crushed, dried, and calcined seashell particles or powders were used as aggregates [ 32 , 33 , 34 , 35 ] or cement [ 36 , 37 , 38 , 39 ] substitutes and added to concrete and mortar. Finally, scholars investigated the physical [ 28 , 29 , 40 , 41 ], mechanical [ 33 , 40 , 42 , 43 , 44 ], and durability [ 35 , 38 , 45 , 46 , 47 ] properties of seashell concrete and mortar by configuring concrete and mortar with different replacement rates to determine the optimal replacement rate and provide guidance for engineering practice.…”

Nowadays, the sustainable development of the construction industry has become a focus of attention. Crushing and grinding waste seashells originating from the fishery industry, such as oyster shells, cockle shells, mussel shells, and scallop shells, into different particle sizes for usage as aggregate and cement in concrete or mortar provides an effective and sustainable solution to environmental problems by reducing natural resource dependence. Numerous studies have attempted to analyze the suitability of waste seashell as a possible alternative to natural aggregates and cement in concrete or mortar. This paper presents an up-to-date review of the characteristics of different types of waste seashell, as well as the physical, mechanical, durability, and other notable functional properties of seashell concrete or mortar. From the outcome of the research, waste seashell could be an inert material, and it is important to conduct a series of proper treatment for a better-quality material. It is also seen from the results that although the mechanical properties of seashell concrete have been reduced, they all meet the required criteria set by various international standards and codes. Therefore, it is recommended that the replacement of seashells as aggregate and cement should not exceed 20% and 5%, respectively. Seashell concrete or mortar would then have sufficient workability and strength for non-structural purposes. However, there is still a lack of investigation concerning the different properties of reinforced concrete members using seashells as the replacement of aggregate or cement. Further innovative research can solidify its utilization towards sustainable development.
