    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

    Extraction of natural aggregates is expensive and has a huge impact on the environment. The main issues in sand and gravel mining are the large areas that are affected, ground water level changes, illegal mining, unsuitability of desert and marine sand, and costs of transport. Metallurgical waste can be used as a substitute for natural aggregates, the waste is recycled and the use of natural aggregates is reduced. Environmental sources are diminishing every day and hence, usage of available sources become even more important..The novelty of this research reports the experimental examination of applying Recycled Aggregate (RA), Treated wastewater (TW) and GGBS in concrete. Four groups of mixes were developed (Groups NW, TW, NWG, and TWG) with each group consisting of four mixes, providing a total of 16 mixes. Group NW: 100% Natural Water (NW) with different percent ratio of RA contents Group TW: 100% Treated waste water (TW) with different percent ratio of RA contents Group NWG: 100% Natural Water (NW) and 50% GGBS (replacement with Portland cement [PC]) with different percent ratio of RA content Group TWG: 100% TW and 50% GGBS (replacement with PC) with different percent ratio of RA contents The test result are compressive strength tests after 1,7,15, and 28 days. The statistical analysis results showed that the effect on concrete compressive strength was only significant when 20% RA was used in concrete exposed to TWW with 50% replacement of GGBS
