SUITABILITY OF APPLYING TREATED WASTEWATER IN REINFORCED CONCRETE MIXING AND CURING

Abstract

The objective of this thesis is to study the effect of using treated wastewater in mixing and curing of concrete to identify the suitability of its usage. The problem is that potable water is considered to be scarce in many of the world’s countries and finding applications for treated wastewater reuse is very effective in preserving potable water resources. The thesis compares the concrete properties for specimens mixed and cured by three different types of treated wastewater which are primary, secondary and tertiary treated wastewater to that for specimens mixed and cured by potable water. The concrete properties included in the study were: (Setting time, compressive strength, tensile strength, bond strength, abrasion, density, absorption, voids, sorptivity, sulfate attack, and corrosion probability), and these properties were assessed since the time of mixing till concrete age of 180 days.
