preparation example Construction

[0024] The preparation method of the surface reinforcement material of the cement concrete pavement of the present invention comprises the steps: (1) dissolving silicon dioxide in the defoamer to make the solution uniform; (2) adding zirconium dioxide and adding the defoamer for the second time (3) Add lithium silicate, heat, rise to 95-105°C, stop heating, and cool down; (4) Add zirconium dioxide for the second time, cool down to 60-70°C; (5) Add lithium silicate for the second time , heating to raise the temperature, adding a dispersant and a stabilizer to cool the solution down to room temperature.

[0025] Stir in step (1) for 5-10 minutes to make the solution uniform;

[0026] The defoamer described in step (2) dissolves and generates heat so that the solution temperature is 60-70°C;

[0027] Add lithium silicate solution in step (3), stir for 15-20min, heat to raise the solution temperature to 95-105°C, and continuously stir to lower the solution temperature to 92-95°C;...

Embodiment 1

[0036] The surface strengthening material of cement concrete pavement includes 4.5 parts of silica, 88 parts of lithium silicate, 3 parts of zirconia, 2.5 parts of dispersant, 3 parts of defoamer and 1 part of stabilizer;

[0037] The preparation method is as follows:

Abstract

The invention relates to the field of inorganic materials and in particular relates to a surface-layer strengthened material of a cement concrete road surface and a preparation method of the surface-layer strengthened material. The surface-layer strengthened material of the cement concrete road surface, provided by the invention, is prepared from silicon dioxide, lithium silicate, zirconium dioxide, a dispersant, a de-foaming agent and a stabilizing agent. After the cement concrete road surface is coated with the material provided by the invention, the anti-freeze-thawing effect is remarkable;the material provided by the invention is simple to use and only needs to be uniformly sprayed; the material can be absorbed within 1.5h and does not need to be cured; the inorganic type surface-layer strengthened material of the cement concrete road surface has a good curing effect and a production process has no pollution, so that the material is suitable for being popularized in a large scale.

Description

technical field [0001] The invention relates to the field of inorganic materials, in particular to a surface reinforcement material for cement concrete pavement and a preparation method thereof. Background technique [0002] At present, cement concrete projects such as cement concrete pavement, airport runway, bridge deck, tunnel and port wharf have been subjected to the reciprocating and alternating loads of vehicles and heavy machinery for many years, resulting in cracks in the pavement and cement concrete structures. Make the original function disappear, especially the bumpy concrete road surface not only makes the driver miserable but also has great potential safety hazard. In the actual process of concrete cement compounding reaction, a small amount of calcium hydroxide does not react and cannot form calcium silicate compounds, which will lead to the decrease of the strength of the cement pavement, easy cracks and other conditions that affect the use. [0003] For the ...
