Abstract

The invention relates to an anti-corrosion anti-cracking reinforcing agent composition for concrete, mortar, and net slurry used in injection (first-aid repair) engineering, and a preparation method thereof. The composition comprises the following components on a percentage basis: 2-50% of micro-expansive powder, 5-30% of reinforcing powder, 5-20% of anti-corrosion compacting agents, 10-20% of plasticizers, 1-6% of catalysts, and 10-60% of carriers. The composition of the invention prepares solid and liquid products by processes of melting refinement, polymerization, ball milling, jet milling, complex formulation, and the like, and thus meets construction process requirements of different first-aid repair endurance engineering.

Description

technical field [0001] The invention relates to an admixture for concrete, mortar or clean slurry, in particular to an anti-corrosion and anti-crack reinforcing agent composition for concrete, mortar and clean slurry in emergency repair engineering (spraying) and a preparation method thereof. Background technique [0002] With the widespread development of infrastructure durability projects such as railways, highways, civil air defense, subways, hydropower, metallurgy, and coal, saving cultivated land, energy conservation, environmental protection, and sustainable development have become important issues, and tunnel engineering accounts for an increasing proportion of the entire project. Large amount of admixtures must be used for excavation of tunnel engineering, support and lining of dangerous rocks. In particular, most tunnel projects are in the environment of water seepage, corrosion, and toxic gas leakage. In addition, the pressure load of the dangerous rock itself seri...
