Processes for producing monolithic architectural cementitious structures having decorative aggregate-containing cementitious surfaces

摘要

A decorative aggregate-containing cementitious slurry having decorative aggregate and cementitious matrix composition forms a monolithic structure when effectively applied to a freshly poured cementitious base and simultaneously cured therewith. The slurry and the base are cured for a time sufficient for producing the monolithic structure with a decorative aggregate-containing cementitious surface. The slurry produces a decorative aggregate-containing cementitious layer having a cured thickness effective for permanently securing the decorative aggregate therein with a portion of the decorative aggregate exposed. Various decorative surfaces are produced without requiring expensive hand broadcasting of the decorative aggregate, and without expensive surface grinding. Dry components of the slurry are decorative aggregate and decorative cementitious matrix blend. The blend at least has between about 50% and about 79% blended quartzitic silica, between about 20% and about 35% Portland cement, silica fume up to about 5%, and optionally up to about 8% Class C-like fly ash.
