Product of Cement-bonded Bagasse Fiber Board

Abstract

This paper aim to describe the manufacturing process of cement-bonded bagasse fiber board by using Portland cement type 1 as cementitious material, bagasse fibers were utilized as reinforcement material, and while grinding limestone were aggregates. The admixture formulation and forming fiber board were defined according semi-automatic shaking process. Physical and mechanical tests accord with TIS 878-2537 standard about standpoints cement with high density. From testing results, crushed limestone instead of sand usage improved the strength of the product, and the density of the sample could be reduced to reach the standard. The bagasse fibers in higher doses admixing effected to increase bending strength, but the density and thermal conductivity values were decreased slightly. The reasonable ratio of commercial usage was Portland cement type 1: grinded limestone: bagasse fiber: water set at 1: 2: 0.2: 0.4 by weight, respectively, that appeared the cement-bonded bagasse fiber board had low cost and all properties of the product reached the standard of Thailand.
