Abstract

The invention discloses as-cast finish concrete and belongs to the technical field of building materials. The as-cast finish concrete is prepared by stirring and mixing the following components: 90 to 100 parts of river sand, 30 to 40 parts of Portland cement, 10 to 20 parts of fly ash, 10 to 20 parts of silica fume, 10 to 20 parts of mineral residues, 20 to 30 parts of water, 20 to 30 parts of silane coupling agent, 10 to 20 parts of polyallylamine aqueous solution, 10 to 20 parts of peach gum liquid and 10 to 20 parts of nano coconut carbon fibers; diatomite of which the mass is 0.05 to 0.06 time that of the Portland cement is also added in the as-cast finish concrete. The surface density of the as-cast finish concrete prepared by the technical scheme adopted by the invention is effectively improved, so that the as-cast finish concrete has excellent carbonation resistance, permeability resistance and crack resistance.

Description

technical field [0001] The invention discloses a fair-faced concrete, which belongs to the technical field of building materials. Background technique [0002] Fair-faced concrete refers to a cast-in-place concrete project that uses the original concrete pouring surface or the concrete surface that is protectively treated with a transparent protective agent as the outer surface, and achieves an aesthetic effect through the natural color and texture of the concrete and the appearance quality of carefully designed construction. One-time pouring without any external decoration is the two most critical points of fair-faced concrete. In recent years, fair-faced concrete has been more and more used in industrial and civil construction projects, and its main features are as follows: ① Improve project quality. Fair-faced concrete does not require any modification, and the quality is "fine, fine, and beautiful". The construction process requires strict division of labor and special ...
