Abstract

The modern civil engineering constructions have their own structural and durability requirements related with concrete to better suit the intended function of the structure. It is necessary to develop the concrete with special properties, so that the structure continues to perform its intended purpose. The inclusion of fly ash, alccofine and steel fiber could be a solution for the demand in concrete for the modern construction. Based on the research done on the concrete containing these materials, it is observed that, the replacement of cement by fly ash reduces the workability and strength of concrete, but 25% replacement can be used as an optimum dosage for the structural concretes which reduces the cost by 7%. Inclusion of fly ash also increases durability of concrete by enhancing resistance to drying shrinkage and freezing and thawing action in the concrete. It is found that replacement of cement by alccofine in the concrete increases the strength and workability and can be used up to 15% as an optimum dosage. Hence, alccofine along with super-plasticizers can be used to develop high strength self-compacting concrete. Addition of fibers has a great advantage in improving both strength and durability properties. Especially the steel fibers up to 1% addition can increase inherent tensile strength, flexural strength and resistance to drying shrinkage and freezing and thawing of concrete. Hence, the environment friendly concrete with self-compacting ability, high strength and better durability properties can be manufactured using industrial waste as mineral admixtures along with steel fibers.
