Abstract:

Canola oil, refined mineral oil, and crude oil additions up to 10% of the aggregate mass in Portland cement mortars were found to decrease the 28-day compressive strength by 71%, 75% and 50%, respectively, and retard setting times. There was a progressive impact upon cement hydration as the oil content increased in mortars. Only in the case of vegetable oil and refined mineral oil could strength loss be attributed in part to cement hydration inhibition, as evidenced by reduced total evolved heat. It is likely that microstructural effects were also a key factor in strength loss for all mortars particularly for those containing crude oil.
