This paper presents the experimental investigation into the properties of mortar blocks containing waste concrete ash (WCA) as a cement replacement. In the experimental investigation, the properties of the mortar blocks were assessed through 3 different type of mixing. The replacement of waste concrete ash (WCA) had been divided into percentage which 0% (control), 5 %, 10 % and 15%. This different type of mixing had been tested with different duration with 7 day, 14 day and 28 day. Three cube specimens and three blocks specimens were prepared for each test. The total specimen that were prepared and tested are 36 cubes and 36 blocks. Workability test (slump test), density test, ultrasonic pulse velocity test, compressive strength test, flexural test and water absorption test were carried out. The experimental results of this study indicate that to observe the inclusion of waste concrete ash (WCA) in mortar blocks enhances the properties of mortar blocks in aspect of replacement of cement.Â
