Influence on durability of concrete with different types of cement, pozzolonic materials & epoxy coating on concrete exposed to different types of acid exposure.

Abstract

The concrete is a highly alkaline material and it is highly susceptible to acid attack. The concrete is one of the most useful materials for storage tank of different types of acids in Industries. Thus the durability of concrete against acid attack is one of the great concern in industries. In this paper the research work was carried out on influence of different types of cement, pozzolonic materials and Epoxy coating on concrete durability against different types of acid attack like H2SO4, HNO3 & H3PO4. From the research work it has been observed that concrete with normal Portland cement shows more deterioration than concrete with Portland composite cement and also concrete with Pozzolonic materials like Fly ash & GGBS shows extensive resistance against acid attack in concrete due to consumption of Ca(OH)2 in concrete through Pozzolonic reaction. The research work also shows that concrete with GGBS in concrete & also concrete with external protective coating of Epoxy paint has high potential resistance against acid attack in concrete.
