A Study Of The Impact Of Steel And Coir Fiber In Coconut Shell As The Coarse Aggregate Of Modified Concrete

Abstract

The results of the best mix design for the mechanical and durability properties of the mixes of Coconut Shell + Fly ash + Coir Fiber Reinforced Concrete (CSFCC) and Coconut Shell + Fly ash + Steel Fiber Reinforced Concrete (CSFCS) are discussed in this chapter. The findings of tests on the characteristics of CS aggregate materials and test mixes for enhancing the strength of CS concrete are presented in this chapter. The following stage is to create a series of trial mixes with the maximum strength feasible after the mechanical characteristics of CS aggregates have been established. In the trial mix preparation, adjustments were made to the fine aggregate, CS aggregate, super plasticizer, and water-binder ratios. The best performing mixture out of a total of 17 experimental mixes was chosen for mechanical examination.  Two different mixes are made, one with coarse aggregate made of coconut shell (CSFCC) and the other with coarse aggregate made of conventional material (CSFCS). Class F fly ash is used to replace 0, 10, 20, and 30% of the cement, respectively, in weight terms. The CSFCC and CSFCS Mixes possessed properties such slump, density, compressive strength, tensile strength, that were both fresh and hardened.
