Embodiment

[0057] 1. Preparation of repair materials

[0058] According to 3 different batching methods in Table 1, and adopt the following preparation method to prepare the repairing material of the present invention.

[0059] 1) Take the corresponding proportion of Portland cement, sulfate cement and fiber and stir it with a mixer for 10-15 minutes;

[0060] 2) Combine the mixture obtained in the above 1) with heavy calcium stone powder, quartz sand, polycarboxylate water reducer, silicone defoamer, silicone water repellent, redispersible latex powder, tartaric acid, carbonic acid Put lithium and cellulose ether into the mixer and stir for 30-45 minutes;

[0061] 3) Packing and packaging the materials prepared above.

[0062] Table 1

[0063]

[0064] In the embodiment, the fibers are mainly polyvinyl alcohol fibers and carbon fibers, and the usage ratio is not particularly limited, but polyvinyl alcohol fibers:carbon fibers=5:1 is preferred. In addition, the type of sulphoalum...

Abstract

The invention discloses a cement concrete pavement patching material. The cement concrete pavement patching material consists of the following materials in percentage by weight: 15.6%-23.6% of portland cement, 15.6%-23.6% of sulfate aluminum cement, 6%-15% of ground calcium carbonate powder, 2.5%-7% of redispersible latex powder, 0.08%-1.8% of lithium carbonate, 0.7%-1.03% of fiber, 0.1%-0.22% of tartaric acid, 0.02%-0.06% of cellulose ether, 26.56%-59.04% of quartz sand, 0.08%-0.25% of a polycarboxylate water reducer, 0.08%-0.33% of an organic silicon antifoaming agent and 0.2%-0.55% of an organic silicon water repellent. The cement concrete pavement patching material disclosed by the invention is adopted, so that ultra-thin patching, ultra-strong compressive strength bonding strength and ultra-strong durability can be realized, and therefore, the damaged part of the cement pavement can be timely repaired without the need of closing traffic for a long time.

Description

technical field [0001] The invention relates to the field of cement pavement maintenance technology and materials, in particular to a cement concrete pavement repair material and a preparation method thereof. Background technique [0002] Road maintenance has always been one of the important topics in the field of road engineering, among which cement concrete pavement is a relatively important pavement structure form in my country's road construction. However, with the growth of time, many cement concrete roads have broken slabs and cracks are very serious. In the cracks, due to rain erosion, the road surface damage continues to increase, and the cost of excavation and reconstruction is very high. Therefore, the damaged road surface must be repaired. repair. Traditional repair materials include asphalt or resin, etc., but asphalt has low melting point, low strength, and is brittle and brittle; resin is not strong in adhesion, easy to fall off, and the effect is not good, an...
