Problems solved by technology

[0004] At present, the repair materials on the market are divided into epoxy resin, high alumina cement, sulphoaluminate cement and magnesium phosphate quick repair materials. The high price and poor durability of epoxy resin materials limit their application in the repair field. Large-scale application, but high-alumina cement, sulphoaluminate cement and magnesium phosphate repair materials have poor anti-freeze and salt-freeze resistance, and are prone to secondary damage after repair

Abstract

The invention relates to a quick repair material for an anti-freezing and anti-salt-freezing airport cement pavement and a preparation method of the quick repair material. The repair material is prepared from two components, namely a powder material and a liquid material. The powder material comprises high-alumina cement, sulphoaluminate cement, Portland cement, gypsum, fly ash, silica fume, mixed quartz sand, a retarder, an early strength agent, a water reducing agent, a defoaming agent and a waterproof component. The liquid material is a silica sol modified emulsion. On one hand, the repair material has excellent freezing resistance and salt freezing resistance, on the other hand, the production cost is greatly reduced, the environmental pollution is reduced, and obvious economic, environmental and social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a frost-resistant and salt-freeze-resistant airport cement pavement rapid repair material and a preparation method thereof. Background technique [0002] Cement concrete is widely used in the pavement of airport flight areas because of its strong bearing capacity, convenient construction and low cost. Cement concrete is vulnerable to freeze-thaw and deicing salt freeze-thaw damage, especially in the northern severe cold regions, due to the long-term freeze-thaw cycle and deicing salt freeze-thaw effect of cement concrete pavement, the surface corrosion damage is serious, which seriously affects the operation of the airport Safety. [0003] The damaged cement concrete pavement needs to be repaired quickly to meet the navigable strength requirements in a short time. At the same time, the repair material should have excellent anti-freezing and salt-freezing properties to...
