Problems solved by technology

The functions of superplasticizer products are concentrated in water reduction enhancement and workability improvement. The improvement and improvement of anti-crack and anti-corrosion performance not only has no effect, but also has certain negative effects.
The production process of water reducer products requires high energy consumption (coal, gas, electricity). In the case of lack of resources and energy, this has formed a great contradiction with large-scale capital construction.

Abstract

The invention relates to a high-performance anti-cracking anticorrosive water reducing agent composition and a preparation method thereof. The anti-cracking anticorrosive waterproof anti-frost property of the water reducing agent composition is improved while the water-reducing rate of the water reducing agent composition is increased. Compared with a water reducing agent in the prior art, the water reducing agent composition has excellent combination property and an anti-cracking anticorrosion effect. When the water reducing agent composition is prepared, low energy is consumed, and when the water reducing agent composition is used, little pollution is caused.

Description

technical field [0001] The invention relates to a water reducer composition, in particular to a high-performance anti-crack and anticorrosion water reducer composition and a preparation method thereof. Background technique [0002] In the construction of modern foundation projects, water reducing agents are widely used in cement concrete, mortar, and clean slurry. Adding water reducing agent during construction can save cement consumption by 5-25%, reduce water consumption by 5-25%, increase building structural strength by 10-30%, and speed up the construction period to save labor and equipment rental fees, and It can meet the technical requirements of modern pumping construction technology. my country is a big country in cement production and sales, and my country's cement production accounts for more than 30% of the world's total, which provides a huge market for the application of water reducing agents; moreover, cement is a building material with high energy consumption...
