Investigation of effects of chemicals on strength and durablity of hardended concrete

Abstract

Over the last few decades, the concrete use has expanded dramatically in different types of structures, like industrial, residential, water storage etc. The concrete is generally very strong and can have different properties such as high compressive strength and flexural strength. In terms of resistant to various chemical, the life of concrete is generally affected by the hardening method, finish etc. and the materials proportion. The concrete deteriorates chemically in acidic environment. Concrete structures can be exposed to academic environment in a variety of environments including acid spills, acid rain, drainage systems, chemical plants, hot springs and industry wastewater. In the below case, the acidic that act on concrete are different and the span of the attack can vary from minutes to number of years.
