Abstract

Concrete is generally used as the main component for the construction of wastewater treatment units. The raw sewage containing chlorides, sulphates, biogenic sulphates, and being acidic in nature has a significant effect on the strength properties. Supplementary cementitious material GGBS are being used in increasing quantities in concrete and have shown to provide concrete with increased strength properties in this particular environment. The experimental analysis was done with a total of 9 different concrete mixes which were prepared with partial replacement of cement with GGBS at various proportions of 0%, 5%, 10%, 15%, 20%, 25%, 30%, 35% and 40% and cured in normal tap water for 28days and then immersed in wastewater for 90days. The specimens were tested for compressive, split tensile and flexural strength for the purpose to identify the optimum dosage of GGBS that performs better in wastewater environments. The test results proved that the concrete mixtures containing GGBS at proportions 25-30% in replacement of cement had not much effect on strength properties and can perform better in such wastewater environments compared to other mixes when tested for respective 28 and 90days strength
