PROCESSES FOR PRODUCING MONOLITHIC ARCHITECTURAL CEMENTITIOUS STRUCTURES HAVING DECORATIVE AGGREGATE-CONTAINING CEMENTITIOUS SURFACES

摘要

A decorative aggregate-containing cementitious slurry havingdecorative aggregate and cementitious matrix composition forms amonolithic structure when effectively applied to a freshly pouredcementitious base and simultaneously cured therewith. The slurryand the base are cured for a time sufficient for producing themonolithic structure with a decorative aggregate-containingcementitious surface. The slurry produces a decorative aggregate-containing cementitious layer having a cured thickness effectivefor permanently securing the decorative aggregate therein with aportion of the decorative aggregate exposed. Various decorativesurfaces are produced without requiring expensive hand broadcastingof the decorative aggregate, and without expensive surfacegrinding. Dry components of the slurry are decorative aggregateand decorative cementitious matrix blend. The blend at least hasbetween about 50% and about 79% blended quartzitic silica, betweenabout 20% and about 35% Portland cement, silica fume up to about5%, and optionally up to about 8% Class C-like fly ash.
