Q: Which fo the follwoing is NOT an advantage of using composite cement lime mortar over cement mortar?
  • A. High Workability
  • B. High drying shrinkage
  • C. High water retention
  • D. Low drying shrinkage
Correct Answer: Option B - Lime-Cement Mortar (Composite Mortar) – It is obtained by adding cement to lime mortar to improve its qualities with respect to gain of early strength, ultimate strength and water tightness. The advantages of lime in composite mortar is that it increases the water retentivity of mortar, improves working qualities, bonding properties and frost resistance. The mortar gives good and smooth plaster finish and is used in building. Cement Mortar Cement mortar consists of cement (as binding material), sand in different proportions and water. Cement mortar when used for plastering, rendering, smooth finishes and damp proof course. Low workability and high dry shrinkage.
