“…Drying or calcining are used to dehydrate and sterilize the seashells, further reducing the organic content. The equipment used by the researchers to grind seashells varied; the most common was a drum compactor [ 41 ], jaw crusher [ 25 , 69 , 70 ], and hammer [ 58 ]. The seashells used as fine aggregate, coarse aggregate, and cement in concrete also varied in size.…”

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.

“…In past studies, the application of seashell materials in cement-based materials has been well-tested mechanically [64,65]. The current processing methods for seashell materials are mainly rinsing, drying or calcination, grinding, and sieving to obtain the required particle sizes [66][67][68]. The results show that adding seashell materials will reduce the strength of concrete, and when the replacement rate of concrete is below 20%, the concrete strength attenuation will be relatively weak [69][70][71][72].…”

The use of seashells to replace traditional cement-based materials and study their adsorption capacity for pollutants can expand the functional engineering application range of cement-based materials. A large amount of seashell waste is produced in coastal areas every year. How to deal with and utilize this seashell waste is a common problem faced by coastal countries and regions. This paper first reviews the principles of adsorption kinetics and adsorption isotherms to demonstrate the adsorption mechanism of shell materials. Then the effects of pH, contact time, temperature, pollutant concentration and other factors on the adsorption of heavy metal ions and basic dyes to seashells are discussed. Finally, the relevant applications of seashells in the construction field are reviewed. The results showed that the optimal pH value in the process of seashell adsorption was 5–7, the active site on the surface of the seashell particles was limited, and that it would reach saturation at a certain concentration, but would not further increase with the increase of time. The active site area of the seashell would increase with the decrease of particle size, so the selection of seashell powder with small particle size was conducive to enhancing the absorption capacity and removal efficiency. The experimental use of seashells instead of cementitious materials or natural aggregates in cement-based materials showed good adsorption capacity and would have a wide range of application prospects in permeable concrete and architectural coatings. By analyzing the research progress on factors influencing seashell adsorption performance and the applications of seashell adsorption behaviors in cement-based materials, this paper could provide ideas and methods for the design of functional cement-based adsorption materials from multiple angles.

“…Nowadays the most common method of determining the concrete strength is to test in simple compression [12]. 4) The maximum and minimum compressive strength of concretes with LWA 10 % and LWA 50 %, respectively, shows that the compressive strength of specimens of LWA concrete depend on the sample amount of LWA.…”

This paper presents an investigation to make the study on workability and strength properties of concrete which is made by Lightweight Aggregates {i.e. Palm Oil Shell (POS) and Pumice Aggregate (PA)}as coarse aggregate. A series of tests conducted in lab containing Slump test, Compaction Factor test, Schmidt Hammer test and Compressive Strength test was led on concrete made by ordinary aggregate as normal weight sample and concrete formed by different ratios of POS and PA separately i.e. 10% to 50% of dry weight of coarse aggregate. All the specimens were underwater for 3, 7 and 28 days as curing stage. In this experimental study, an effort has been made to concentrate the properties of a lightweight concrete M30 using the lightweight aggregate (POS and PA) as a partial replacement to coarse aggregate. The test results indicate that with the increasing amounts of normal aggregates replaced by POS and PA, the slump test, compaction factor test and strength of the Lightweight Aggregate Concrete (LWAC) has reduced gradually. As water absorption of the LWAC has been increased step by step with the increasing amounts of aggregates replaced by POS and PA. Lastly, it is concluded that the use of POS has great future than compared to PA in the construction of structural lightweight concrete.
