Advantages of dry construction of lightweight gypsum mortar

Dry construction means that there is no need to water and moisten bricks, blocks and other blocks and base layers before construction. High-performance mortar is directly used for dry brick masonry and dry wall plastering. The mortar is cured naturally after hardening (no need to A construction method that requires sprinkling and curing).

With the increasing proportion of new wall materials used in construction in my country year by year, some quality problems have also arisen, the most prominent of which is wall cracks. This is because new wall materials are very different from traditional sintered clay bricks in terms of material properties and water absorption properties. If the construction technology and materials of sintered clay bricks are still used to build new wall materials and carry out When plastering a wall, there will inevitably be project quality problems. The most effective way to solve this problem is to use high-quality ready-mixed mortar. By adding water-retaining thickening materials and a small amount of additives, the properties of the mortar are fundamentally improved, such as cohesive properties, water-retaining properties, etc., making the mortar It is well bonded with the base layer, and the water retention rate of the mortar is high (generally greater than 98%). The water will not be absorbed by the base layer, and the cement in the mortar can be fully hydrated, thereby ensuring the compressive strength and tensile strength of the mortar. Tensile bond strength. Due to the use of high-quality ready-mixed mortar, the blocks or base layer do not need to be watered in advance, allowing dry application of the mortar.

Dry construction of mortar has the following advantages:

①Excellent water retention, which can ensure that the mortar gels under better conditions, thus improving the bonding strength and Strength;

②Good fluidity can make the mortar more easily penetrate into the bonding base surface, increase the contact area, thereby improving the bonding force of the mortar;

③Better The initial bonding force is conducive to filling the vertical mortar joints of larger-sized block walls with mortar to ensure the integrity of the wall;

④ Better slurry lifting ability can ensure a dense plaster layer , The surface is smooth and the inside and outside are uniform.

Therefore, the use of dry construction with mortar can significantly improve the water retention, initial bonding strength and construction performance of the mortar, making it easier to rub the mortar, making the mortar dense and smooth, ensuring that the mortar is used optimally The gel hardens under the conditions, effectively inhibiting the new generation and development of cracks, and can significantly improve the integrity, stability and durability of the plaster layer. Not only that, dry construction can also be widely used in interior and exterior wall decoration, effectively avoiding wall cracking, hollowing, and water leakage. It can also greatly reduce the labor intensity of workers, improve work efficiency, and shorten the construction period. It saves 2/3 of water consumption compared with traditional construction methods, and can also meet civilized construction and environmental protection requirements. It brings considerable economic and social benefits and has broad market prospects. </p
