What is Consistency?
The term stability of masonry mortar refers to its property of mobility or fluidity. Consistency means the property of holding all the ingredients together without separating the mortar. It generally ranges from hard to fluid. The working consistency of mortar is usually decided by the worker during application.
What are the factors affecting the consistency of mortar?
The consistency of the mortar mix depends on the following factors.
- composition of mortar
- type of masonry
The water should be sufficient to maintain the fluidity of the mortar during application, but at the same time it should not be excessive enough to separate the aggregate from the cemented material.
The amount of water needed to maintain consistency or fluidity will also depend on the masonry in which the mortar is used. Thin joints will require more fluidity; Bed joints subjected to heavy pressure may require a hardening mortar.
