Product CEMEX Shotcrete - Product CEMEX Shotcrete - CEMEX UAE ReadyMix
CEMEX Shotcrete is a specially designed concrete developed for use with compressed air spraying equipment. Shotcrete is a fast and effective way to apply concrete in areas where using conventional concrete would be difficult. CEMEX Shotcrete also forms an integral part of an innovative low cost, low carbon housing solution.

How to use
- Two different processes are used, either the wet process or the dry process.
- In the wet process, all the concrete constituents are batched and mixed together before being fed into a pump. The mixed concrete is conveyed under pressure to the nozzle where compressed air is injected, shooting the concrete into position.
- In the dry process, only the dry ingredients are batched together and pumped under pressure to the nozzle. Pressurized water is introduced at the nozzle, which, along with the force from the pump, projects the concrete into the area being repaired. The addition of water is therefore under the control of the nozzle operator in the dry mix process and the end product tends to be more variable.
