Question

Statement (I): Preparing mortar by using masonry cement improves workability as well as the finish during plastering.

Statement (II): Masonry cement is easy to handle. 

1. Both Statement (() and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)
2. Both Statement (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of Statement (I) 
3. Statement ((I) is true but Statement (II) is false
4. Statement (I) is false but Statement (II) is true

Answer 1

Correct Answer - Option 2 : Both Statement (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of Statement (I) 

Concepts:

Masonry cement:

• Masonry cement is obtained by intimately grinding a mixture of Portland cement clinker and gypsum with pozzolanic or inert materials (for example limestone, conglomerates, dolomite, granulated slag) and air entraining plasticizer in suitable proportions, generally to a fineness greater than that of ordinary Portland cement.
• It has a property of producing a smooth, plastic, cohesive and strong; yet workable, mortar when mixed with fine aggregates and is considered superior to lime mortar, lime-cement mortar or cement mortar. Thus, it is chiefly intended for use in masonry mortars for brick, stone and concrete block masonry, and for rendering and plastering work.
• Ordinary cement mortars, although fast setting and capable of high strength development, are harsh, non-plastic and non-cohesive with the result that they cannot take up the shrinkage and temperature, so results in cracks. Masonry cement eliminates this problem.

Hence, masonry cement improves workability as well as the finish during plastering and it is also easy to handle. But the mortars are prepared by using masonry cement not due to it is easy to handle but due to its additional advantages over other cements. Hence, both the statements are correct but statement II is not the correct explanation of statement I.
