Changes in temperature and humidity have a very important impact on self-levelling construction. And poor solutions can lead to a range of quality problems.

Basis for adjustment of cement self-levelling formulations at low temperatures.

It is well known that cement self-levelling formulations are complex and have many components. Some raw materials have a glassing temperature of less than 5┬░C, which can slow down or stop the reaction of the components during low temperature construction. Resulting in anomalies in the self-levelling and even affecting the final strength. By clarifying the role and performance of each component, you can choose the right specification material to adjust the formula and formulate a cement self-levelling for use at low temperatures. Or you can even for construction at negative temperatures.


Basis for formulation adjustment of cement self-levelling at high temperatures.

When the temperature rises, the components react faster, especially the cement and gypsum materials react violently. This requires the selection of a suitable retarder and an appropriate increase in the amount of admixture.

Adjustment of cement self-levelling formulations during the dry season.

During the dry season, self-levelling water evaporates quickly, making it easy to form cracking and chalking phenomena. The recipe should be adjusted to increase the amount of water retention agent and the water reducing agent and retarder should also be adjusted.

High humidity season (or environment) for cement self-levelling formula adjustment basis.

In the high humidity season, self-levelling water evaporates slowly and is prone to non-setting or cracking. The formulation should be adjusted to reduce the amount of water retaining agent in time and the water reducing agent and retarder should also be adjusted appropriately.
