Abstract

The invention discloses anti-freezing concrete which is made of the following substances: cement, silica powder, mica powder, attapulgite, calcium carbonate, urea, zinc chloride, calcium sulfate, river sand, stone, additives and water. As the components of the concrete are specially improved, under the cooperative action of the components, the finally made concrete has the advantages of being highin strength, good in toughness, good in cracking resistance, good in seepage prevention, good in low temperature resistance, high in stability, and the like, and has great market competitiveness andpopularization and application values.

Description

technical field [0001] The invention belongs to the technical field of concrete processing, and in particular relates to antifreeze concrete. Background technique [0002] Concrete is widely used in engineering fields such as underground engineering, bridges, pools, water towers, culverts, tunnels, docks, dams, hydropower stations, etc. It is usually required not only to have high strength, toughness and stability, but also to have certain waterproof, Freeze resistance. Especially in the alpine region, the temperature difference changes greatly, and the concrete is prone to cracks, brittleness, and water seepage after repeated freezing and melting processes, and its strength, toughness, and stability are seriously affected. However, most of the conventional concretes that are directly mixed with cement, sand, and stones with water cannot meet the above requirements and need continuous improvement. Contents of the invention [0003] The object of the present invention is ...
