Fast setting cement – a method of producing.
Developed a new method of producing quick-setting cement, comprising adding to cement an active mineral supplements. The application of the proposed method allows 2-3 times to reduce the cost of production of rapid-hardening cement, and the complexity of the concreting work when using rapid-hardening cement is reduced in 1,5 – 2 times compared with traditional methods and materials.
Description:
Developed a new method of producing quick-setting cement, comprising adding to cement an active mineral supplements. As such an additive is used a mixture of fine sand with the accelerator setting (as accelerator is taken potash and fluoride of sodium in the amount of 6% and 2% by weight of cement).
When mixing such a cement mixture heated to 50-60 °C water ensures fast setting of the cement, regardless of the impact of the environment, including in sub-zero temperatures, which allows to use this method at any time of the year.
Advantages:
the application of the proposed method allows 2-3 times to reduce the cost of production of rapid-hardening cement,
– the complexity of works on concreting when using rapid-hardening cement is reduced in 1,5 – 2 times compared with traditional methods and materials
– the cement setting at low temperatures, which allows to use it at any time of the year.
