Appropriate Ratio for Using Water Hyacinth Fibers for Making Cement Fiberboard
Keywords:Water Hyacinth fiber, Cement fiberboard, Thermal insulation
The objective of this research was to study a suitable ratio of using water hyacinth fiber as a mixture of high-density cement fiber board. The admixtures consisting of cement, fine sand, water hyacinth fibers, water, and cement forming accelerators (Aluminium Sulphate (Al2(SO4)3), Calcium Chloride (CaCl2), Sodium Silicate (Na2SiO3)) were respectively mixed in 5 mixing ratios by weight: 1: 0.2: 0.3: 0.000: 0.03, 1: 0.2: 0.3: 0.025: 0.03, 1: 0.2: 0.3: 0.05: 0.03, 1: 0.2: 0.3: 0.075: 0.03 and 1: 0.2: 0.3: 0.1: 0.03. A total of 20 mixing formulas were used in forming cement board sheets with a compactor. The sheets were then tested for the properties in compliance with TISI 878-2537: Standard for High-Density Cementitious Veneer. From the results at 28 days of curing, Formula B3 ratio of 1: 0.2: 0.3: 0.05: 0.03 (cement: fine sand: water hyacinth fibers: Calcium Chloride (CaCl2)) was the most suitable ratio as the properties met the standard, TISI 878-2537 (only the bending strength was slightly lower than the standard).
