A study of durable and reliable reactive powder concrete containing rice husk fibers

Abstract

Natural fibers have seen a surge in popularity over the past decade as a direct response to the growing num-ber of people who are concerned about the environment. The use of natural fibers has many advantages, including their low cost and their little impact on the environment. Rice husk is a byproduct of milling rice and is frequently regarded as a waste product by many people. However, it has a number of possible appli-cations, one of which is the use of its natural fibers in the production of bio-composites. In this paper, ex-perimental work was carried out to study the effect of Rice Husk Fibers with a volume fraction of one per-cent on the properties of Reactive Powder Concrete (RPC), utilizing various temperatures curing for four hours due two days after hardening the sample directly, and the optimal temperature that will give the high-est strength will be adopted to study the effect on some mechanical properties. Rice Husk Fibers were added to the RPC mixture at a volume fraction of one percent. These characteristics include the compressive strength, dry density, and slump of the material. According to the findings, the compressive strength of the RPC grew by 7.4%, while the dry density reduced by 0.69 % after being heated to 60 °C for 28 days. On the other hand, the RPC's workability decreased by 5.62 % when compared to the reference mixture.
