Compared with the construction process of cement mortar, the final setting time and curing cycle of lightweight gypsum mortar are greatly shortened, allowing the next process to enter the site earlier, greatly shortening The construction interval from plastering to surface layer saves a lot of time. Owner and general contractor money. Time and cost, especially for time-critical projects.
Lightweight gypsum mortar is not easy to shrink, so the measured data after survival is relatively stable. The vertical smoothness of lightweight plaster mortar surfaces is easy to control, easy to maintain and can be thinned. Cement mortar measurements are difficult to control and maintenance requires cutting and chipping. The material is green and can be recycled. The construction environment is good and there is little waste. The price of lightweight gypsum mortar seems to be higher, but in engineering applications, its comprehensive cost is no higher than the price of traditional plastering materials. For example, the thickness of the plaster layer of lightweight gypsum mortar can be less than 3mm, while the thickness of the plaster layer of cement mortar should be greater than 6mm-8mm.
Lightweight gypsum mortar has good viscosity and micro-expansion, solving common quality problems of traditional mortar, such as hollowing, cracking and falling off, reducing rework and repairs work and save a lot of materials and manpower. The volume of cement mortar will decrease during the hardening process, while the volume of gypsum slurry will harden easily and lose elasticity, and the volume will increase. The two materials harden at different rates, gypsum is faster and cement is slower. Due to differences in hardening time and hardening properties, cracks and peeling are prone to occur between them.
The most important component of mortar is vitrified beads, which are commonly used thermal insulation materials in modern buildings and have good thermal insulation properties. It uses acid glass as the main raw material and is processed with high technology. </p
