Abstract

Reactive Powder Concrete (RPC) is a concrete of the modern generation it mainly contains a high percentage of cement and a small percentage of water For cement as well as the presence of fine sand, ground quartz and silica dust. This research aims Studying the behavior and mechanical characteristics of RPC exposed to elevated temperatures. The key variables in this study are steel fibers content and the high temperatures of different levels 25, 200, 300, 400 ºC. Mechanical properties of concrete behavior including compressive strength, splitting tensile strength, stress-strain relationship (modulus of elasticity), and flexural strength. The test findings indicated that the Output strength of RPC specimens decreased when the high temperature increases. At a temperature of 400 °C, all samples lost the compressive strength and splitting tensile strength.
