Effect of Alccofine and Fly Ash Addition on the Durability of High Performance Concrete

The aim of this Study is to evaluate the performance of concrete (HPC) containing supplementary cementitious materials such as Fly ash & Alccofine. The necessity of high performance concrete is increasing because of demands in the construction industry. Efforts for improving the performance of concrete over the past few years suggest that cement replacement materials along with Mineral & chemical admixtures can improve the strength and durability characteristics of concrete. Alccofine (GGBS) and Fly ash are pozzolanic materials that can be utilized to produce highly durable concrete composites. This study investigates the performance of concrete mixture containing Local Alccofine. in terms of Compressive strength, Sulphate Attack tests, Alkali test and RCPT (Rapid chloride penetration test) at age of 28 and 56 days. In addition find out the optimum dosage of alccofine and fly ash from that get M70 Strength, in final mix proportion perform a given test. Result show that concrete incorporating Alccofine and fly ash had higher compressive strength and alccofine enhanced the durability of concretes and reduced the chloride diffusion. An exponential relationship between chloride permeability and compressive strength of concrete is exhibited.
