Why should the clay bricks be watered first when they are building masonry walls?
And because a portion of the water in the mortar brick absorb, can lead to early dehydration, but are not very good on the hydration of the brick and mortar bond strength weakened, greatly reduce mortar and masonry compressive strength, shear strength, affecting the integrity and seismic performance of masonry.
Sintered clay brick because there are a lot of capillary, in the dry state water absorption ability is very strong, if you don't use water, water in the mortar will soon be sucked out of the brick, mortar workability is reduced, operation is difficult to spread the real tile.
Therefore, in order to facilitate the operation, so that the mortar has a suitable hardening and strength growth environment, to ensure the quality of masonry, bricks must be watered before use wet.
