Influence of high volume fly ash as a replacement of cement and sand along with glass fiber on the durability of concrete

Abstract

Dumping of fly ash is an emergent challenge in India day by day. The capacity of the landfill area decreases with continuously increasing the amount of fly ash. Due to restrictions of government on natural sand mining from a watercourse, contractors are demanding reliable partial replacement material for sand. Many Researchers carried out an investigation on durability properties of concrete by partially replacing cement with fly ash along with the different type of fibers. However, the influence of high volume fly ash as partly alternative for cement and sand along with glass fibers does not exist in the literature. The objective of this study is the use of alternative sustainable material such as fly ash as a partial substitute for cement and sand in concrete. Also, to check the effect on fresh and hardened properties of proposed concrete. A present study shall be a right action for reducing the utilization of cement and natural fine aggregate moreover consuming a higher amount of fly ash accessible in India for durable concrete. Based on the test result carried out in the present study indicate the improvement in compressive strength, electrical resistivity, ultrasonic pulse velocity and decrease the shrinkage in concrete.
