Question No : 9
Assertion A : For identical strength, a composite cement-lime mortar is preferred over cement mortar.
Reason R : Composite cement-lime mortar has higher drying shrinkage than cement mortar. Select your answer based on the codes given below:
Question No : 10
Assertion A : Lime based mortars give higher ratio of brickwork strength to mortar strength as compared to non-lime mortar. Reason R : Lime based mortars have lower bond strength as compared to non-lime mortars. Select your answer according to the codes given below:
Question No : 11
