A Study on Mechanical Properties of Bamboo Fiber Reinforced Foam Concrete

Abstract

This study aims to enhance the performance of foam concrete through the incorporation of bamboo fibers and it also to investigate the suitable mix proportions for establishing linear correlations between cement paste and dry density. A foam concrete density of 700 kg/m³ was selected as an appropriate value and the cement used in the experiment was 0.702 kg. A water-to-cement ratio was 0.702 kg, and the admixture of polyurethane form was 0.85 liters. The research includes an evaluation of compressive and flexural strengths, involving the curing of foam concrete specimens for a duration of 28 days. A comparative analysis is undertaken, contrasting the compressive strength of bamboo fiber-reinforced foam concrete in two distinct categories: 1) specimens treated with a concrete bonding agent and 2) those without such treatment. Notably, the flexural strength of unreinforced foam concrete was set at 1,215 kg/cm³, while the incorporation of bamboo fibers passing through the center with a diameter of 0.95 cm results in a reinforced foam concrete flexural strength of 8,854 kg/cm³. The results reveal that bamboo can be utilized as a reinforcement material in foam concrete to enhance the tensile strength.
