Material for destroying concrete structures

A material for destroying concrete structures, rock formations and the like comprises a mixture of 20 to 80 parts by weight of coarse-grained quicklime adjusted to a particle size of from 88 to 3000 microns, and 20 to 80 parts by weight of cement. The cement may contain calcium sulfoaluminate as a h...

Beschreibung
Zusammenfassung:	A material for destroying concrete structures, rock formations and the like comprises a mixture of 20 to 80 parts by weight of coarse-grained quicklime adjusted to a particle size of from 88 to 3000 microns, and 20 to 80 parts by weight of cement. The cement may contain calcium sulfoaluminate as a hydraulic component, and a retardant may be added to the mixture to retard the hydration of the calcium sulfoaluminate. The material is blended with water and then injected into holes formed in the body to be destroyed, the material expanding as it hydrates to crack and fracture the body.
