4. Conclusions
- (1)
- The compressive strength, flexural strength and modulus of elasticity value of epoxy mortar containing filler up to 20 wt. % improved by an average of 1.08–1.66, 1.18–1.66, and 1.07–1.54 times, respectively, at different weight fraction of epoxy in the range of 10–25 wt. % when compared to the control specimens.
- (2)
- It was observed that when filler is used at optimum level, it can improve bond strength; all the mortars except those prepared with epoxy at 10 wt. % showed a good bond strength higher than 1.5 MPa.
- (3)
- It can be established that sand washing waste can be used as potential filler for epoxy resin mortar to obtain better compressive, flexural, stiffness, and bond strength.
- (4)
- This study does not cover all the parameters required to examine repair materials for concrete structures; further investigations on compatibility issues such as dimensional change stability of the epoxy resin mortar containing sand washing waste filler is required.
