Will the aerated concrete block brick use special masonry and plaster mortar?
The formation of pouring through the phenomenon
Aerated concrete block brick to use a special masonry and mortar, is due to aerated block closed porous performance, so that the surface of the water fast, and to the inside is difficult
With the method of wetting in advance is not the first application of aerated blocks, when the use of traditional mortar admixture water retention is poor, in the paving gas block, the mortar in the water is aerated block absorption, resulting in cement Full, strength can not play properly, mortar bonding and low compressive strength, mortar and block adhesion is not strong and affect the masonry quality, cracking, hollowing, shedding, fault Another ordinary mortar compressive strength is higher, while the aerated block compressive strength is low, the two performance does not match So the traditional mortar admixture is not suitable for puffing gas block Adhesive block used in the masonry mortar, the first water retention is better, this can prevent the water in the mortar is sucked away, both to ensure the construction of the operation is conducive to the development of mortar strength to have a higher bond to To ensure the quality of masonry Aerated concrete block is a kind of lightweight and porous, thermal insulation, fire performance is good, can be nailed, sawing, planing and have a certain seismic capacity of new building materials As early as the early thirties, China began to produce this product, and widely used
