What is the difference between finished mortar and cement mortar?

Finished mortar according to the material classification belongs to the mixed mortar, sand and cement, lime according to a certain proportion of the mixture, called "mixed mortar", mixed mortar due to the addition of lime paste, improve the mortar's ease of operation is more convenient, cement mortar is cement + sand + water composition of the mixture, sometimes also add a certain amount of The cement mortar is a mixture of cement + sand + water, sometimes with a certain amount of additives (such as waterproofing agent, antifreeze, early strength agent, etc.) The strength of this mixture is the highest in the case of the same ratio of the above kinds of strength.

Difference between finished mortar and cement mortar:

Cement mortar is synthesized by three main materials, cement, sand and water, while mixed mortar is synthesized by four main materials, cement, sand, lime and water.

Finished mortar is suitable for dry areas because of the addition of lime, which retains water well, while cement mortar is suitable for wet areas because of its high strength.

The finished mortar is easy, easy to mix, conducive to the improvement of masonry compactness and efficiency; cement sand waterproofing is good, suitable for external wall paste wall bricks, internal wall clear light

The finished mortar is whitish with lime reference, while the cement mortar is dark gray and black.
