Construction technology of cement mortar

1. The basic technology of cement mortar plastering. Find the rules → find the corners of the wall → level the horizontal line, hang the vertical line straight → make standard grey cakes and screed → find the corners of yin and yang → plaster the interior wall → the bottom layer is lower than the screed → level the middle layer with screed → decorate the surface layer.

2. Key points of cement mortar plastering construction Standard ash cake must be prepared before plastering.

3. The screed is also an important link to ensure the quality of plastering, and it is an important control sign when plastering in a large area.

4. Finding the angle of Yin and Yang is also an important process directly related to the quality of subsequent decoration projects.

Strictly speaking, the mixture ratio has a great relationship with the particle size, water content, actual strength of cement and construction level of sand. Assume that cement is 32.5 (actual strength is M7.5), medium sand is used, the water content of sand is 1.5%, the construction level is normal, the preparation strength is 8.7 1MPa, and the mixing ratio of cement mortar per cubic meter is (weight ratio): cement: sand = 1.565438.
