How does gypsum waterproofing affect the hardening process of concrete?


Gypsum waterproofing agent reacts with calcium hydroxide in concrete to form hydrated calcium sulfoaluminate, which promotes the hardening process of concrete. At the same time, gypsum waterproofing agent can also inhibit the shrinkage of concrete and reduce the occurrence of cracks.


What effect does gypsum waterproofing agent have on the strength of concrete?


Appropriate amount of gypsum waterproofing agent can improve the strength of concrete. Because the gypsum waterproofing agent can fill the tiny gaps in the concrete and reduce internal defects, thereby improving the compactness and strength of the concrete.


How durable is plaster waterproofing?


The durability of gypsum waterproofing agent is related to many factors, such as the quality of concrete and environmental conditions. Generally speaking, high-quality plaster waterproofing agents can provide waterproof protection for a longer period of time and maintain good performance.


How to choose a suitable plaster waterproofing agent?

Choosing a suitable gypsum waterproofing agent needs to consider factors such as project requirements, concrete type, and environmental conditions. Gypsum waterproofing agents should be selected that have good compatibility with the concrete materials used, stable performance, and meet environmental protection requirements.


Are plaster waterproofing compounds compatible with other additives?


When choosing to use other additives, testing and verification should be conducted first to ensure compatibility and synergy between the gypsum waterproofing agent and other additives. Avoid performance degradation or material deterioration due to chemical reactions.


How to deal with the impact of gypsum waterproofing agent on the human body?


When using gypsum waterproofing agent, appropriate protective measures should be taken, such as wearing masks, gloves, etc. If it accidentally comes into contact with skin or eyes, rinse immediately with clean water and seek medical advice promptly. At the same time, long-term inhalation of dust or gas released by gypsum waterproofing agents should be avoided.
