The Compressive Strength of Post-Fire Concrete Prepared with Bamboo Fiber

Abstract

The purpose of this research was to identify the compressive strength of the concrete post-fire with the addition of bamboo fiber length variation. This research used quantitative experimental method. The independent variables were bamboo fiber length variation (2 cm, 3 cm and 4 cm by 1.5% proportion of cement weight, and the combustion temperature variation (200 °C, 300 °C and 400 °C). The dependent variable was compressive strength of concrete. The result showed that the addition of bamboo fiber length variation and combustion temperature variation producing the maximum unit of concrete compressive strength was found in bamboo fiber with length of 2 cm and burned at 200 °C. The value decreased with the increase of combustion temperature. The length of 4 cm bamboo fiber produced the highest compressive strength with the maximum compressive strength 20.93 MPa.
