Durability of concrete is a vital property that affects its serviceability. One of the factors that affect concrete durability is sulphate attack, which can result to expansion, cracking, deterioration and deformation of concrete structures. However the present study focuses on affect of sulphate on concrete durability In this research the findings of various research papers were studied wherein different tests were performed on different types of concrete specimens. The specimens varied in size were and subjected to multiple test settings. These different tests are compressive strength, Elastic modulus, Weight evolution, Load displacement curve, Erosion age etc. For each of the aforementioned tests the results were different for eg. The result of compressive strength tests of the specimen were found to have reduced in the beginning when the concentration of solution is increased but with the passages of time it shows an increasing trend.
The effects of different concentrations of sulfate for erosion age on compressive strength, flexural strength, weight analysis, density loss and visual appearances for concrete specimens of different grades were investigated. Experimental studies were carried out on different grades of concrete (M-25, M-30 and M-35). Concrete specimens were immersed in different concentration of sulfate solution i.e. 4.0pH, 5.0pH and 6.0pH. Reduction in compressive strength loss was noticed when the grade of concrete is increased from M-25 to M35. The results of weight analysis and density analysis also confirm the compressive strength loss and flexural strength. Discoloration of concrete was noticed on the concrete blocks when left immersed in sulfate solution at 4.0pH, 5.0pH and 6.0pH for 75days and 90days. It appeared like flakes of concrete and resembled like mold growth.
