Which is better, lightweight gypsum or cement mortar?

Lightweight plastering gypsum is better. Lightweight plastering gypsum has the characteristics of light weight, less construction consumption, environmental protection, convenient construction and installation, waterproof and moisture-proof.

1, lightweight plastering gypsum can solve the problem of hollowing and cracking after scraping cement mortar. The bonding ability of light plastering gypsum is twice that of traditional cement mortar, and the shrinkage rate is only 0.04%, which is ≦0.3% of that of cement mortar. Because the elastic modulus of light plastering gypsum is low, the stress accumulation is less. Therefore, the phenomenon of hollowing and cracking is not easy to occur after scraping the wall with light plastering gypsum, which can effectively solve the quality problems of traditional cement mortar after construction and avoid the trouble of hollowing and rework in the later stage.

2, fast construction, high efficiency, time-saving and labor-saving. Mechanized construction of lightweight plastering gypsum has the advantages of high speed, saving working hours, no need to roughen the interface mortar between concrete wall and aerated concrete wall, and reduced construction steps and materials. There is no need to sprinkle water during the maintenance period after construction, which saves construction time and water resources, can effectively improve construction efficiency and reduce construction cost. In the same building, light plastering can save more than ten days' construction period than cement mortar. After the construction of light plastering gypsum is completed. You can scrape putty on the same day.

3. The comprehensive benefit is high. The unit price of cement mortar is cheaper than that of light plastering gypsum, but the construction cost of light plastering gypsum is much lower than that of traditional cement mortar. According to the dosage, under the same construction area, the dosage of lightweight plastering gypsum is only a quarter of that of cement mortar, and there is basically no loss. Moreover, due to the small dosage, the load on the wall is reduced and the safety is improved a lot. Lightweight plastering gypsum can be mechanized, and the efficiency of mechanized construction is much higher than that of manual construction, and the efficiency is improved by 200%. From the perspective of comprehensive benefits, lightweight plastering gypsum is a building material that can effectively replace traditional cement mortar, and has the effects of strong adhesion, anti-arching, anti-cracking, heat insulation and sound insulation.
