Abstract: Chapter 1deals with Introduction to treated domestic waste water utilized in concrete preparation where there is a scarcity of fresh water. Chapter 2 discusses physical properties of Materials and chemical properties of treated domestic waste water. Experimental program is presented in Chapter 4 mix proportion for M20 and M40 grade concrete are presented in this chapter. Number of specimens to be cast for different curing regimes is also presented in this chapter. Chapter 3 elaborate average compressive strength results of M20 grade concrete cast by using Tap water as mixing and curing water for Mix M1 & treated domestic waste water as mixing and curing water for Mix M2 Similarly average compressive strength results of M40 grade concrete cast by using Tap water as mixing and curing water for Mix M3 & treated domestic waste water as mixing and curing water for Mix M4. Discussion of results covers, M20 grade concrete at the age of 7days the average compressive strength for all the 2 mixes is nearly same. At the age of 14days marginal increase in compressive strength is observed in case of mix M1 but in case of mix M2 compressive strength remains same as that of 7days.And at 28days curing age decrease in compressive strength was observed .This decrease in compressive strength may be due the use of treated domestic waste water for mixing and curing.
