Sulphoaluminate Cement needs to be prepared with a certain proportion of cement slurry. You can use a regular concrete mixer, liquid mixer, or manual mixing method. During the preparation of the slurry, it is crucial to control the ratio of cement to water. Generally, the water-cement ratio of sulphoaluminate cement is between 0.4~0.5. Too high or too low will affect the quality of the slurry.
Before starting the construction of sulphoaluminate cement, it is necessary to clean the construction site, remove dust, oil stains, and other debris, and ensure that the construction surface is dry and flat. Meanwhile, the packaging bag of the sulphoaluminate cement needs to be opened, the cement poured into a clean container, and the tools and auxiliary materials required for construction prepared.
Apply Primer
First, use a sulphoaluminate cement primer to coat the construction surface once. After the primer dries, proceed to the next step of construction.
Apply Sulphoaluminate Cement
Evenly apply the prepared sulphoaluminate cement slurry on the construction surface. Generally, it needs to be applied 2~3 times, with an interval of 4~6 hours between each layer, waiting for the previous layer to dry thoroughly before proceeding to the next application.
Curing of Sulphoaluminate Cement
After completing the application, it needs to be cured for a certain period. You can use a wet cloth to cover the applied surface to avoid rapid drying, which can cause cracking or deformation. Generally, sulphoaluminate cement needs to be cured for more than 7 days.
During the preparation and construction of sulphoaluminate cement, it is necessary to follow certain safety measures, such as wearing protective gloves, masks, goggles, etc., to avoid harm to the skin and respiratory system.
During construction, ensure that the usage amount and dilution ratio of sulphoaluminate cement are well controlled. Do not arbitrarily change the ratio, as it will affect the quality and strength of the cement stone.
When using sulphoaluminate cement, pay attention to controlling the temperature and humidity of the construction environment. Especially in severe environments like high temperatures, low temperatures, and high humidity, adequate protective measures need to be taken.
Before construction, surface cleaning treatment is required to avoid quality issues like cracks and bubbles in the cement stone.
If you encounter problems while using sulphoaluminate cement, you should promptly contact the manufacturer or relevant professionals for assistance and solutions.
The above are the usage methods and precautions for sulphoaluminate cement. Only with correct usage methods and sufficient precautions can the stability and high-strength cement stone formation of sulphoaluminate cement be ensured.
