Abstract
The invention relates to an architectural concrete product and a preparation method thereof, and belongs to the technical field of architectural concrete materials. The product comprises a concrete base layer, a mortar surface layer and a protection layer, the mortar surface layer is located between the concrete base layer and the protection layer, the mortar surface layer is stonelike mortar containing colored sand, and the protection layer is a transparent nano-silicon protection agent. The concrete product has the advantages of a stable structure, a flat and attractive surface, excellent stain-resistant performance and good weather fastness and chemical resistance.
Description
technical field [0001] The invention relates to the technical field of decorative concrete materials, more specifically, it relates to a decorative concrete product and a preparation method thereof. Background technique [0002] Decorative concrete adopts surface treatment technology to carry out surface coloring and strengthening treatment on the surface of concrete base, so that the concrete surface has color effect and anti-penetration protection effect, and achieves the effect of beauty and decoration. It is widely used in residential, community, commercial, municipal and Sidewalks, parks, squares, playgrounds, etc. in various places such as entertainment, with good safety and durability. However, concrete itself is a kind of non-uniform porous material, which is easily corroded by carbon dioxide, water, chloride ion, sulfate and other media, and will also affect its surface treatment effect, affecting the smooth appearance and anti-fouling durability of the decorative c...
