A REVIEW ON DEVELOPMENT OF HIGH PERFORMANCE CONCRETE BY USING RECYCLED AGGREGATE AND FLY ASH

Structural engineering

There is a growing demand for the development of new type concrete due to its high strength, performance, durability, serviceability and overall economy in long term. High performance concrete meets all of the above criteria to fulfil our needs. This project is aim at developing such High Performance Concrete that can provide the enhanced mechanical strength to the concrete. The concrete made of such strength uses Silica Fume, Recycled Aggregates and Super plasticizers that enhance the concrete properties. In this study the compressive strength and split tensile strength of High Performance Concrete mixtures for different percentage of replacement of cement with silica fume are reported. It is found that maximum increase in compressive strength and split tensile strength is for concrete mix in which 8% silica fume will replace with cement. Due to these outstanding properties, High Performance Concrete provides new possibilities of lighter and larger structures with economy and resource consumption than that of traditional concrete, steel and other building materials
