Influence of River Water and Treated Industrial Sewage Water Quality on Compressive Strength of Concrete with Sawdust Ash as Partial Replacement of Cement

Abstract

The study centered on the effect of different qualities of water on concrete compressive strength. The concrete mix of M25 grade with a water-cement ratio of 0.45 was investigated. Water samples, such as portable water, river water, and treated industrial sewage water were collected from Hassan city and were used to cast 150x150x150mm concrete cubes. The cured cubes were crushed on 7, 14, 21 & 28 days for compressive strength estimation. The results showed that the compressive strength of the concrete cubes made with portable water, river water, and treated industrial sewage water increased with days & not have many variations in their compressive strength The optimum replacement ratio was about 12%. This may be considered a solution not only to the problem of the environment but also to the problem of economics in the design of buildings. the combination of treated wastewater and saw dust ash greatly influences the compression strength of the concrete. The aim of the present study was to know the effect of chemical impurities in mixing different types of water on the compressive strength of concrete.
