| Abstract | ||||
| Rice straw ash (RSA) is an agricultural waste product which is produced in large quantities globally every year. Due to the difficulty involved in its disposal, it is becoming an environmental hazard in rice producing countries. In Egypt, RSA presents an important environmental impact. One way to reduce the impact of the construction activity is by substitute pozzolanic materials for ordinary Portland cement (OPC). In this work, an experimental study was conducted on the effect of partial replacement of OPC with RSA on the Engineering properties of cement mortar. Control mortar mix with OPC was made and in other mixes OPC were replaced with RSA up to 75 % by weight. The work focused on some physical and mechanical properties of the OPC- RSA mortar. It consisted of: density, porosity, water absorption, setting time, flexural, compressive strength, and scanning electron microscopy (SEM). The results showed that both initial and final setting times increased with increasing the RSA replacement percent. OPC-RSA mortar gave excellent enhancement in strength for 15 % replacement. Moreover, up to 20% of OPC could be valuably replaced with RSA without adversely effecting in strength. Further, hydration reactions of OPC-RSA mortars were investigated using SEM at 28 days. | ||||
