Low cement castable mixing and construction

The water used for stirring must meet the drinking water standard, with pH of 6-7. Strictly control the amount of water added, the amount of water added to the material must be accurately weighed.

The suitable casting temperature of the castable should be between 15ºC and 30ºC, the ideal temperature is 21ºC. When the casting is performed below the recommended temperature, external heating measures should be taken to increase the temperature of the environment;
The stirring time should be controlled within 5 ~ 10 minutes, it is recommended not to exceed 10 minutes. The mixed materials must be poured within 30 minutes;
The vibration of low-moisture castable is critical. The vibrating rod should move up and down in the material. When the vibration comes to the end, the vibrating rod should be slowly pulled out;
After the casting is completed, the molds can be removed after 18-24 hours according to the hardening of the material, make sure the material must be completely hardened. Do not damage the material surface when demolding;
After demolding, it should be kept at room temperature for 24-72 hours, and then be sintered.
