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:
Consider the following statements:1. Masonry in rich cement mortar though having good strength with high shrinkage is much liable for surface cracks.2. Lime mortar possesses poor workability and poor water retentivity and also suffers high shrinkage.3. Masonry in lime mortar has better resistance against rain penetration and is less liable to crack when compared to masonry in cement mortar.Which of these statements are correct?
