Abstract

Abrasion resistance is a key concern for castables used in various applications in cement and boilers, where the temperatures vary between 800-1100°C. The current study is evaluating the effect of grain size distribution on the abrasion resistance of low cement castables commonly used in such applications that  fails due to lack of abrasion resistance. Experiments have been conducted both at room and high temperatures to simulate the conditions existing in reality. Studies have revealed the fact that the varying grain size distribution has a strong influence on the abrasion resistance of castables while keeping the other variables such as chemistry, cement content etc,. at the  same level.
