(I) on Common Problems of Self-leveling Cement Construction

 self-leveling cementConstruction common problems
1. self-leveling coating area reduced
1. Influence of construction technique and proficiency of construction workers;
2. After stirring, the stagnation time is too long, causing the self-leveling flow to deteriorate;
3, the ground water absorption is too fast to make the self leveling in a relatively short period of time to lose mobility;
4. The interface agent is unevenly rolled;
5. Wrong construction thickness;
6, self-leveling quality problems.
7. Too much or too little water;
8. The construction temperature is too low;
2. self-leveling shell, cracking
Sand from the original ground;
Places not coated with interface agent or not covered by interface agent;
The original floor is not thoroughly cleaned. Legacy: dust, old powder, metal powder;
Ground water or acid, alkali, salt, oil and other ingredients;
The original ground is non-absorbent ground example: marble floor, tile floor, steel floor, etc., but did not choose the corresponding interface agent;
There are cracks in the original ground, and the shrinkage joints are not filled before self-leveling;
Self-leveling quality problems.
Too many self-leveling pores in 3.
Sand from the original ground;
The original ground dries and absorbs water faster;
Places not coated with interface agent or not covered by interface agent;
The sealing effect of the interface agent is not good.
4. glue coating scratch area is small
Without self-leveling;
Construction technique and proficiency of workers;
The type of scraping gear does not correspond;
Low construction temperature;
Low construction temperature;
