Which is better, gypsum mortar or cement mortar? What is the construction method of gypsum mortar?

Gypsum mortar is stronger than traditional cement mortar, and its construction is simple and efficient. It can also prevent cracks and falling off, reduce rework, and the comprehensive project cost is relatively cheap. So, which is better, gypsum mortar or cement mortar? What is the construction method of gypsum mortar? We will explain it for you.

Which is better, gypsum mortar or cement mortar?

1. Gypsum mortar basically overcomes the problems of bulging, cracking and falling off of plastering layer. At the same time, the plastering period is shortened, which is 1.5-2 times higher than that of the traditional cement mortar plastering treatment process.

2. The density of plastering gypsum slurry is 1_/L- 1.3_/L, the density of concrete lime slurry is 1.7_/L- 1.8_/L, and the plastering thickness is13 _-

3. In order to make high-quality wall with 100_, the labor quota of the actual processing technology must be: 83.4h of plaster of Paris mixture and 167.2h of concrete lime powder mixture. Compared with gypsum mortar, these two methods reduce a lot of practical operation procedures and save 1 times the working cost.

4. Gypsum mortar can save the processing technology of mortar sitting on the concrete surface and reduce the plastering time limit.

5. Implementing decorative design on plastered gypsum mortar elastic coating can save decorative coatings and installation glue, such as 0.3 _/_-0.5 _ _ for general wall and 0.2 _/_-0.3 _ _ for plastered gypsum wall.

6, plastering gypsum mortar early strength fast hardening, suitable for the time limit for a project.

7. Gypsum mortar has a strong cohesive force, which basically eliminates the hollowing and cracking of the wall and reduces rework.

8. During the construction of gypsum mortar project, there is less ash, which reduces the consumption of raw materials and eliminates the employment.

9. Gypsum plastering is more suitable for winter construction than mortar cement sand oars, which can save a lot of heat preservation costs.

10. Gypsum mortar is a class A fireproof material, which can improve the fire safety, sound insulation and heat insulation of buildings.

1 1. The retail price of gypsum mortar seems expensive, but in engineering application, the comprehensive engineering cost is not more expensive than the traditional plastering raw materials. For example, the wall thickness of gypsum mortar plastering layer can be less than 3mm, while the plastering thickness of cement mortar must be above 6 mm-8 mm

Gypsum mortar construction method

Basic treatment

1, before the construction, remove the dust, oil stains, stains and protective objects on the bottom in advance;

2, the pit bottom part of the convex and concave, pit edge to solve clearly, keep flat and solid;

3. The gap between the door frame and the corner should be determined according to the embedded density of doors and windows made of various materials;

4. Wet the bottom layer with tap water in advance, and pay attention to the fact that there can be no Mingshui County on the surface before plastering.

5. Start making the stigma of walls, door dialogs and corners.

Practical operation processing technology

1, define the plastering sequence, do it first, and then gradually start from the front, and all the walls will continue to dry.

2. Cement concrete ceiling can be painted with plastering gypsum once;

3, according to the smoothness of the wall at the grass-roots level, set the standard reinforcement or standard reinforcement; The spacing of vertical standard poles should be 1.2- 1.5m, and the total width of standard poles should be 0.03-0.05m ..

4. When the plastering thickness is less than 0.05m, gypsum mortar can be directly used for plastering; If the plastering thickness is above 0.05m, it can be directly placed on the lighter bottom layer, and then the whole plastering gypsum elastic coating can be replaced;

5. Plaster gypsum mortar on the bottom layer according to the design thickness, then use an H-shaped ruler and scraper to cling to the standard reinforcement, and scrape off the ash layer from front to back and left and right.

6, with a ruler, and then use a level to check the flatness of the wall;

7, after rendering should pay attention to timely processing related parts.

8, plaster plaster, cement mortar to remove floor ash, after finishing, we should pay attention to good natural ventilation, to prevent tap water washing veneer. Remember to clean the special plastering tool immediately after operation.

The construction period of gypsum mortar is shorter than that of cement mortar, which is not only fire safety, sound insulation and noise reduction, but also thermal insulation, and can also save money in engineering construction.
