Embodiment 1

[0078] The first step is to spray the base surface with nano-modified silicate infiltration crystalline material, and the spraying amount is 150ml / m 2 , Penetrate to a depth of more than 4mm on the concrete base. The preparation process of the nano-modified silicate infiltration crystalline material is as follows:

[0079] Weigh 0.07 parts of dodecyltrimethylammonia chloride, 0.15 parts of sodium borate, 0.3 parts of sodium thiosulfate, 0.15 parts of ammonium chloride, 0.2 parts of potassium carbonate, 0.15 parts of sodium metaphosphate, 0.15 parts of magnesium fluoride, amino 0.35 parts of sodium alkoxide, 65 parts of deionized water, etc., mixed and stirred in a high-speed shear kettle at a speed of 1000rpm to disperse, and added 23 parts of sodium silicate and 15 parts of potassium silicate while stirring at a high speed until the addition was complete, and the mixed solution was Completely transparent, homogeneous liquid. Among them, the nano-silica active particles have...

Embodiment 2

[0090] The first step is to spray the base surface with nano-modified silicate infiltration crystal material, and the spraying amount is 120ml / m 2 , slice analysis, so that the nano-modified silicate infiltration crystalline material penetrates to a depth of more than 4mm on the concrete base. The preparation process of the nano-modified silicate infiltration crystalline material is as follows:

[0091] Weigh 0.05 part of dodecyltrimethylammonia chloride, 0.10 part of sodium borate, 0.1 part of sodium thiosulfate, 0.10 part of ammonium chloride, 0.15 part of potassium carbonate, 0.10 part of sodium metaphosphate, 0.1 part of magnesium fluoride, amino 0.15 parts of sodium alkoxide, 63 parts of deionized water, etc., mixed and stirred in a high-speed shear kettle at a speed of 1000rpm to disperse, and added 23 parts of sodium silicate solution and 16 parts of potassium silicate solution while stirring at a high speed until completely added, and mixed The solution is completely ...

Embodiment 3

[0102] The first step is to spray the base surface with nano-modified silicate infiltration crystalline material, and the spraying amount is 200ml / m 2 , Section detection, penetration to the depth of 4mm above the concrete base. The preparation process of the nano-modified silicate infiltration crystalline material is as follows:

[0103] Weigh 0.05 part of dodecyltrimethylammonia chloride, 0.10 part of sodium borate, 0.1 part of sodium thiosulfate, 0.10 part of ammonium chloride, 0.15 part of potassium carbonate, 0.10 part of sodium metaphosphate, 0.1 part of magnesium fluoride, amino 0.15 parts of sodium alkoxide, 66 parts of deionized water, etc., mixed and stirred and dispersed in a high-speed shearing kettle with a speed of 1200rpm, and added 20 parts of sodium silicate solution and 18 parts of potassium silicate solution while stirring at a high speed until completely added, and mixed The solution is completely transparent and homogeneous liquid. Among them, the nano-s...

Abstract

The invention relates to a construction method for creating a fair-faced effect on a concrete base surface. The construction method comprises the following steps that 1, concrete base surface coatingis carried out by adopting a nano-modified silicate capillary crystalline material; 2, the concrete base surface is coated with the coloring paste to cover the concrete base surface and / or form surface textures, the coloring paste is prepared by stirring cement-based inorganic powder and an adhesive and adding an inorganic pigment for color mixing; and 3, after the coloring paste is dried, finish-coat coating is carried out by adopting a nano-modified silicate capillary crystalline material, the nano-modified silicate capillary crystalline material comprises the following components of, in parts by mass, 5 parts-30 parts of sodium silicate, 5 parts-20 parts of potassium silicate, 0.05 part-0.5 part of a surfactant, 0.1 part-1 part of a reaction retarder, 0.1 part-0.5 part of a reducing agent, 0.1 part-2 parts of a reaction promoter, 0.01 part-0.5 part of an anti-freezing agent, 0.1 part-1 part of a metal ion blocking agent, 0.1 part-1 part of a surface enhancer, 0.1 part-0.5 part of anantirust agent and 40 parts-70 parts of deionized water. The construction method has a lasting protection effect on concrete, can be particularly applied to the outdoor roof surface of a concrete building, and can maintain the fair-faced decorative effect for a long time.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for creating a clear water effect on a concrete base surface. Background technique [0002] Clear-water concrete and clear-water formwork are a kind of expression technique of architectural modernism, and they are also called decorative concrete because of their great decorative effect. Maintaining the original concrete texture is the direct meaning of fair-faced concrete. Gray is the main color of fair-faced concrete, but irregular texture and indeterminate decoration are the real meaning of fair-faced concrete. Due to domestic construction and development factors, the effect of most fair-faced concrete pouring is not very good. At the same time, most people in domestic fair-faced concrete pouring do not have the concept of protecting concrete. [0003] Imitation fair-faced concrete paint and imitation fair-faced concrete paint are the two most mentioned types of ...
