Effect of curing on adhesion between mortar/concrete

The adhesion between the repair system and the old concrete is one of the main factors for the successful performance of a repair layer. Therefore, this paper investigates the effect of curing on bond strength between cement-based repair mortar and concrete substrate. Curing used include "submerged in water", "with curing agent " and "releasing in exterior space." The bond strength was determined using "friction-transfer" method. The results indicate that the curing provides better adhesion between the repair mortar and the concrete substrate and can prevent separation at their joint boundary.
