Recently, the focus must apply on how to get high sustainability and reduce environmental problems. The thus scientists are focusing to produce Reactive powder concrete for economic and environmental purposes as well as of good mechanical properties. Two types of fibers were used Rice husk fibers (RHF) and Micro steel fibers (MSF) with (1%) by volume of concrete where six combinations were used with different proportions, which are [(0:0), (1:0), (0:1), (0.5:0.5), (0.3:0.7), (0.7:0.3)] for RHF and MSF respectively were used in RPC to investigate how RPC's mechanical characteristics change after being exposed to various temperatures (60¿, 120 ¿ and 200 ¿) for 4 hours over two days, where all mixtures contain the same percentage of basic materials. MSF and RHF were used singly in the mixture and in a hybrid form.
