Effects of Microsilica Percentage Amount on Structure and Compressive Strength of Reactive Powder Concrete (RPC)

摘要

Reactive powder concrete is a new kind of powerful concrete which is called so because of tiny powder and pozzolanic materials as well as a lot of hydraulically active materials used in it and it has been presented by two French scientists in 1994. The aim of this study is to measure the possibility of producing powder concretes using local materials used in Asaluyeh Region. By calculating cement amount, water ratio to cement and optimal percentage of super plasticizer in this article, we start constructing six mix plans with different percentages of microsilica (0, 10, 15, 20, 30 and 40). Results show that 15% mix plan has the highest bending and compressive strength in three conditions of producing regimes.
