Properties of Good Mortar. Strong cement mortars are more likely to cause shrinkage cracks, thus they should be avoided unless a high level of strength is required. On the other side, using a much weaker mortar, such as a 1:10 cement mortar, is insufficient since the lower cement concentration results in reduced workability, cohesiveness, and ...
