Abstract
The colored composite material is manufactured from materials based on a hydraulic binder and dispersed reinforcing elements, for example fibrous. To obtain a colored material, a composition comprising a baked clay such as chamotte is used generally by replacing at least in part the silica in products preferably hardened under steam pressure. The materials obtained are useful particularly as covering elements for frontages in the building industry.

Composition for the manufacture of a colored composite material, of the asbestos-cement type or the like, with good efflorescence resistance, comprising at least one hydraulic cement, a reinforcing filler, and baked clay, the relative proportions of the constituents of the cement and of the clay conforming to the proportions by weight:
- (CaO/SiO.sub.2 +Al.sub.2 O.sub.3) comprised between 0.4 and 1.0, Al.sub.2 O.sub.3 /(SiO.sub.2 +Al.sub.2 O.sub.3) comprised between 0.07 and 0.30, the baked clay being sufficient in proportion to color the material obtained by hardening the composition.
