“…Rather than the water-cement ratio, it is frequently connected to the cement content, needed workability, and air content, because determining how much of the entire mix water is absorbed by the aggregate and hence how much water is accessible for hydration processes is challenging. In a study [1], the compressive strength of a concrete specimen with natural fine and coarse aggregate control specimen is 50.56 MPa after 28 days, indicating that the strength reduction increases as the percentage of replacement increases, reaching nearly half of the control strength (25.21 MPa) after 30% replacement. [21] proved and stated that, the compressive strength test can be used to measure the material's resistance to external loading.…”

“…Research conducted [1] stated that CS concrete is lighter than natural aggregate concrete in lightweight concrete to achieve the requisite concrete strength. Furthermore, in compared to other agricultural waste, CS absorbs less moisture due to its reduced cellulose concentration.…”

“…CS have been discarded might be used as a substitute. A study [1] has investigated on the mechanical characteristics of CS as a fine and coarse aggregate substitute in concrete and the CS concrete was constructed with CS as a replacement for fine and coarse aggregate at 10%, 20% and 30%, respectively, with a characteristic strength of 30 MPa.…”

In most tropical countries, especially in Asia, where afflicted nations included the Philippines, Thailand and Malaysia, agricultural waste was disposed of in enormous amounts. Poorly designed garbage disposal techniques are one of the biggest environmental ills. Environmental conservation efforts have been severely hampered by the disposal and management problems posed by wastes produced by industrial and agricultural operations. This study was carried out to find optimal replacement of coconut shell taken at 7, 14, and 28 days of curing by conducting mechanical properties tests. In this investigation, coconut shell concrete was produced by replacing coarse aggregate with coconut shells by 0%, 10%, 20%, and 30% of the total coarse aggregates. The results suggest that 10% replacement of coconut shell produces the optimum value for coarse aggregate replacement based on the compressive strength and Schmidt rebound hammer test results.

“…Disposal of this abundantly available coconut shell (CS) generated from the coconut industries creates an undesirable effect on the land causing huge environmental impact. Due to its abundant availability in India, a lot of research is going on by using these CS as partial or full replacement of coarse aggregate since the unit weight of concrete produced with CS is smaller because of the unit mass of CS used in the mixture [6][7][8][9][10][11][12][13][14][15].…”

This paper presents the flexural behaviour of concrete containing ground granulated blast furnace slag (GGBS) as a binder, manufactured sand (M-sand) as a fine aggregate, and coconut shell (CS) and crushed stone aggregate (CSA) as coarse aggregates. Alkaline activator sodium hydroxide with 10 molarity and sodium silicate were used in a weighing proportion of 1 : 2.5 to produce structural grade concrete. Out of 12 beams cast, 6 were used to study geopolymer coconut shell concrete (GPCSC) beam behaviour and 6 were used to study geopolymer conventional concrete (GPCC) beam behaviour. Data presented include cracking behaviour, ultimate moment capacitates, deflection behaviour, ductility ratio, and end rotation of the beam. Laboratory investigations show encouraging results, and it can be summarized that coconut shell has good potential as a coarse aggregate for the production of structural grade geopolymer lightweight coconut shell concrete.
