Abstract :

Mortar is one of the most important components in reinforced concrete structural member. In reinforced concrete structures mortar have some inseparable influence. Lacking in mortar strength endanger the whole structure. Now a day it is seen that many structures fails due to lack of strength. So, the mechanical properties of mortar have some critical effect. In this paper an investigative experiment is reported on the mechanical properties of mortar modified by stone dust as replacing material of both fine aggregate and cement. An endeavour has been made to evaluate the appropriateness of stone dust as construction materials. Properties of mortar are investigated with the replacement of 25% and 50% of fine aggregate and also 5% of cement by stone dust. Cubes and briquette samples were casted and tested after a curing period of 3, 7 and 28 days. Several samples were made by using above proportion to get the effect on mortar. Results of this work have indicated that 25% replacement level exhibit higher strength than the controlled sample. Therefore, this paper provides insight regarding how to interpret mechanical properties of mortar, how stone dust as a partially material play a role, and comparative analysis between fresh mortar and modified mortar.
