Abstract

Aerated concrete products, which are cast from mixed materials containing lime and silicic acid with water which is made porous by adding a foaming agent, are provided with a surface dressing of partially embedded mineral grains, e.g. gravel, applied prior to steam curing and which are applied by a compressed air spray as the spray nozzle and the surface are relatively displaced so that 40-60% of the surface is covered by the grains. Circular grains are preferred and 30-70% of the surface of the grains is embedded within the concrete and, after steam curing, the dressed surface may be coated with a translucent or transparent plastics or a lacquer, e.g. an aqueous acrylic dispersion, providing a water repellent surface. The finished products may be employed as floor, roof, or external wall units, masonry blocks, partition wall units, lintels or large panels or as sandwich elements enclosing a core of cellular plastics.
