Problems solved by technology

[0012] Therefore, the technical problem solved by the present invention is to use a single admixture to simultaneously treat concrete, mortar or clean slurry in anti-crack shrinkage, compensation shrinkage, impermeability and water resistance, anti-corrosion and anti-corrosion, prevention of steel bar corrosion, inhibition of alkali aggregate active reaction, anti-freezing and anti-corrosion. The technical problems existing in carbonation, anti-scouring and anti-corrosion engineering can not only ensure the technical performance of concrete, mortar or clean slurry structures, but also improve their comprehensive durability, and can also reduce material costs, mechanical costs, labor costs and maintenance At the same time, it can meet the technical requirements of various construction techniques such as internal mixing and external coating construction, pumping construction, spraying construction, and ordinary construction.

Abstract

The invention relates to an anticorrosion expansion compacting agent composition and a preparation method thereof; the composition comprises the following components by weight: 15-35% of aluminium-containing compounds, 0-8% of zirconium-containing compounds, 2-10% of magnesium salts, 0-3% of titanium dioxide compounds, 0-6% of lithium salts, 2-6% of alkanolamine salts, 0-10% of super-plasticizers, 0-10% of solidification adjusting agents, 0-5% of acids, and the balance of carriers. The components are reacted in a reaction vessel at 80 DEG C+ / -5 DEG C for 3 hours, and then cooled to 45 DEG C+ / -5 DEG C; thermal insulation is performed for one hour; and anticorrosion expansion compacting agents of a standard type, a solidification-promoting type, or a pumping slow-solidifaction type are obtained according to the added solidification adjusting agents with different types and amounts.

Description

technical field [0001] The invention relates to the field of construction additive materials, in particular to an anti-corrosion expansion compacting agent composition and a preparation method thereof which can be used in engineering applications such as concrete, mortar, and clean slurry. Background technique [0002] Concrete, mortar, and clean slurry foundation projects that use cement as the cementitious material are important components of the rapid development of the national economy. China's annual ready-mixed concrete exceeds 900 million cubic meters, ready-mixed mortar exceeds 300 million cubic meters, and clean slurry 100 million cubic meters, other concrete output is 500 million cubic meters, and mortar is 1 billion cubic meters, accounting for 30-40% of the world's annual consumption. Cement is a porous structure material that is brittle, easy to corrode, and easy to shrink and crack. In addition, these structures often Being underground, underwater, or exposed t...
