Abstract
Fresh water scarcity is a major problem all over the world now; all countries are currently striving to preserve fresh water for drinking purposes and to develop waste water treatment plants for reuse in other fields, such as agriculture, landscaping, industrial applications, and many other fields. This thesis includes a study of the effect of using treated waste water on cement mortar and Bearing walls. Therefore, an experimental program consisting of three phases was developed.
The first phase: includes the evaluation of the chemical and mechanical properties of the materials used in the tests.
The second phase: includes testing of mortar cubes made from potable water and mortar made from secondary treated waste water, according to the Egyptian Code for Designing and Executing Masonry Works.
The third phase: is built a masonry prism from bricks using the two types of mortar mentioned above. where tests were conducted (compressive strength, shear strength, in plane tensile strength, flexural tensile strength for out of plan bending). The results showed that the strength of prisms constructed by using mortar made from potable water minor higher than prisms constructed by using mortar made from secondary treated waste water when comparing results after 28 days.
