Experimental investigation of eco-friendly building blocks utilizing coconut shells

In the construction of structures, cement is commonly utilized as a construction material. The high cost of conventional building materials has a significant impact on the structure's economy. Synthetic lightweight aggregate manufactured from environmental trash is a potential new source of structural aggregate material, as concerns about the over use of natural aggregates develop. As more natural resources from the earth's surface are used, they are becoming deficient. Alccofine is a new generation micro fine concrete material for high Strength which is important in respect of workability as well as strength. As a result, the coconut shell is being investigated as a partial substitute for coarse aggregate in building blocks then cast it. The compressive strength, slump, and density of concrete are all evaluated. In the concrete building blocks, the replacement of cement with an Alccofine by 5% and the replacement of coarse aggregate with coconut shell by 0%, 50%, 100%. As the percentage of replacement increased, it was seen that the slump was getting worse. The density also drops as the proportion of replacement rises. The compressive strength is demonstrated to decline as the percentage replacement increases.
