“…Similar results were attained when crushed scallop seashell was substituted as fine aggregate after 28 days at 10%, 20%, and 30%. The strength was reported as 6.95 MPa, 6.65 MPa, and 6.37 MPa, respectively (Chandra et al, 2020). Contrary to results obtained from seashell substituted as fine aggregate, its effect as coarse aggregate replacement indicated an increase in flexural strength for 7%, 14%, 21% substitution ratio, and a decrease at 28%, as shown in Figure 10 ( Raseela & George, 2019).…”

This study reviews recent literature on the mechanical and durability properties of concrete incorporating seashells as partial or full substitutes for conventional materials. The study summarizes various contributions elucidating the various waste seashells utilized, the growing worldwide aquaculture production, seashell material preparation and treatment, chemical composition, physical properties, and different mechanical and durability test methods adopted by previous studies such as compressive strength, split tensile strength, flexural strength, modulus of elasticity, freeze-thaw resistance, water permeability, air content, chemical attack, carbonation, and weight loss. The study showed that mechanical properties indicate reductions of different percentages with increases in substitution ratio at 5% to 75%, compared to control mixes. However, relative increases in mechanical strength were recorded with the increase in curing age up to 90 days. Influence of seashells on durability properties varied across various durability tests at different seashell percentages. In a nutshell, the use of seashells in concrete

Concrete waste generated from construction and demolition is a major problem generated in large quantities. The use of waste concrete as a substitute for conventional aggregate materials is a way to reduce waste generated from construction and sample testing and reduce exploration of natural materials, which have an impact on the environment and damage natural. Waste concrete can be recycled and can be used for various purposes. The use of coarse aggregate ranges from 70 to 80% in concrete mixes so the reuse of recycled concrete coarse aggregate has been widely reported, but few studies have focused on recycling and extracting value from concrete grains. The laboratory test method used several parameters to determine the physical properties of the concrete mixture and the characteristics of the compressive strength of cube concrete 150 mm x 150 mm x 150 mm with a sample size of 12 samples for 0%, and 12 samples for 100% recycled aggregate. The compressive strength of concrete was reviewed 3 and 28 days after treatment according to SNI. The compressive strength of recycled concrete aggregates increased by 11.54% at the age of 3 days and decreased by 27.64% at the age of 28 days.

“…In a recent study, [94], studied concretes in which the fine fraction of the aggregates was partially replaced by crushed Scallop seashells and cement was also substituted, in part, by rice husk ash (RHA). Since no water reducing agents were used, a workability degradation caused by the waste aggregates' addition was to be expected, and thus, the results show that the increase in waste aggregates implied a corresponding loss to the concrete's workability.…”
