5 STUDY ON STRENGTH PROPERTIES OF COCONUT SHELL

the compatibility of coconut shells with cement were studied. Based on the standard procedures and methods followed for the production of conventional LWC, the coconut shell aggregate concrete were produced. Numerous trial mixes were conducted by varying cement content, sand, coconut shells and water-cement (w/c) ratio.

Examining Concrete Properties using Coconut Fiber Ash and

Concrete is a composition of cement, coarse aggregate, fine aggregate and water which makes it a composite material. Fly ash which is a waste material is used as a supplementary cementitious material in the production of Portland cement and when added to concrete, it gives good workability, greater strength, decreases permeability and increases durability. Coconut fiber is an agricultural

An investigation of key mechanical and durability

This study investigated the effect of adding fly ash on the mechanical and durability characteristics of coconut shell (CS) concrete. Two different mixes were developed, one with CS and the other with conventional aggregate and CS as coarse aggregate. Cement was replaced with Class F fly ash in terms of weight at 0, 10, 20, and 30% in both mixes.
