According to the composition materials, ordinary mortar can be divided into: lime mortar. It is made of lime plaster, sand and water according to a certain ratio. It is generally used for masonry and plaster layers that are not high in strength and not subject to humidity; cement mortar. It is made of cement, sand and water in a certain ratio, and is generally used in masonry, walls or floors in wet environments or water;

First, the workability of freshly mixed mortar
After the mortar is mixed and used, it should be contained in the ash storage. If the mortar is bleeding, it should be mixed again before masonry.
The mortar should be used with mixing. Cement mortar and cement mixed mortar must be used within 3h and 4h after mixing; if the maximum temperature during construction exceeds 30 ° C, they must be used within 2h and 3h after mixing.
