Kayati’s CRAS (expansive cement) is an innovative solution for rock excavation and demolition. This expansive cement is designed to break rock in a controlled and safe manner, without the need for explosives or heavy machinery, making it ideal for urban environments and sensitive areas.
Advantages
Security
By not using explosives, the risks associated with handling and detonation are eliminated. This makes it suitable for urban areas and areas close to sensitive infrastructure.
Accuracy
It allows for controlled breaking of the rock, which facilitates obtaining fragments of the desired size and minimises damage to surrounding structures.
Low enviromental impact
The absence of blasting and the reduced use of heavy machinery reduce the environmental impact, making CRAS a more sustainable option.

Frecuently asked questions
CRAS is an expansive cement used for the controlled demolition and fragmentation of rock and concrete without the need for explosives. Its controlled expansion causes fracturing of the materials to which it is applied.
When CRAS is mixed with water and applied to boreholes made in rock or concrete, the cement expands, generating internal stresses that eventually cause the material to fracture within 24 hours.
