Durabilty and Strength Properties of High Volume Fly Ash Concrete

Abstract

Use of High Volumes of Fly Ash in concrete is gaining significance and is considered as a sustainable option for many concrete constructions. Experimental results show that, HVFAC has lower strength at early ages but at later age HVFAC shows continuous increase in strength properties. Significantly both the crack width and drying shrinkage reduce and thus contribute to the long term durability of concrete. HVFA Concrete exhibits comparable costs, increased strengths and enhanced durability. Thus, the HVFA concrete is more suitable for warm weathers and where early strength is not essential. This paper reviews the durability and strength properties of High Volume Fly Ash Concrete.
