A method for producing a composite insulating mineral block, includes providing a mineral masonry block including at least one cell with walls having a water absorption rate of less than 5 g/(m&#xb7;s) at 10 minutes, and filling the cell with a mineral cement foam, wherein a cement used to produce the mineral cement foam has an aluminum oxide content of less than 20% by weight of the cement.

Method for producing an insulating composite building block

The invention concerns a fast binder comprising; cement; at least one superplasticizer; calcium nitrite; and at least one formic derivative. The invention also concerns concrete mixtures obtained from said binder and methods for making same.

Rapid binder compositions containing a calcium salt for concrete components and structures

A demolding composition, to be used for the production of parts of hydraulic-setting material, includes at least one oil and at least one calcium salt, calcium borates and calcium salts of fatty acids being excluded from the at least one calcium salt. A process for the preparation of a part molded in hydraulic-setting material, includes coating sides of an appropriate mold with the demolding composition; introducing a freshly-prepared hydraulic-setting composition; and removing the part from the mold after hardening and optional curing of the composition.
