Study on mechanical properties of silica fume based reactive powder concrete

Abstract

This experiment aims to determine how natural fine aggregate and steel fibre grade affect reactive powder concrete's tensile and compressive strength (RPC). The properties of materials have been studied clearly with their respective reactions in the matrix. Based on previous technical studies on RPC, binder compositions have been derived for observing the standard mechanical behavior changes in the concrete. Concrete samples of four different fibre proportions are prepared with three types of gradation in natural fine aggregates. 135 cubes and 45 cylinders are cast for the literature design and tested for 7, 28, and 56 days, respectively. Analyzing the behavior of the Reactive Powder Concrete is the primary goal of this study, adding its optimum application for actual usage in damaged buildings to minimize the activity of demolition of the building where the cause of increasing stability on the structure is necessary.
