Study of Fiber Cement Board Containing Coconut Coir for Using in Construction Works

Abstract

The purpose of research is to study the proper mixture using coconut coir as an ingredient in fiber cement board production. Use coconut coir which is agricultural waste product for using in construction works. Using assorted coconut coir length at 5, 10 and 15 millimeters at 0%, 2.5%, 5%, 7.5%, and 10%, 12.5%, 15%, 17.5% and 20% by weight of cement. Determine the ratio of Portland cement type 1: sand: water as 1: 1: 0.5 by weight, respectively. The physical and mechanical properties test based on TIS1427-2561 standard on the fiber cement sheets: flat sheets. From the test results of fiber cement board mixed with coconut fibers, it was found that the fiber percentages at 0%, 2.5%, 5%, 7.5%, 10%, 12.5%, 15%, 17.5% and 20% had flexural strength at 1.52, 4.17, 5.14, 5.04, 5.05, 4.07, 4.67, 2.03, and 0.45 Megapascal at 28 days, respectively. This result also demonstrated that the use of coconut coir with mingling length 5-10 millimeters at a higher rate of 15% could be produced the fiber cement board which met requirement of TIS 1427-2561 in terms of the flexural strength of 4 Megapascal.
