Description

A kind of resistance rust concrete and preparation method thereof

Technical field

The invention belongs to building material field, particularly a kind of resistance rust concrete and preparation method thereof.

Background technology

Concrete has abundant raw material, cheap, the simple feature of production technology, thereby make its consumption increasing. It is high that while concrete also has compression strength, good endurance, the features such as strength grade wide ranges. These features make its scope of application very extensive, not only in various civil engineerings, use, and be exactly shipbuilding industry, mechanical industry, the exploitation of ocean, geothermal engineering etc., concrete is also important material.

Along with the development of component materials of concrete, people are to being not only confined to compression strength to concrete performance requirement, but on the basis of basing oneself upon intensity, more focus on concrete durability, deformation performance, fire-and explosion-proof performance, water-impervious performance, toughness, corrosion resistance, heat insulating ability, health environment-friendly and reduce costs etc. the balance and coordination of overall target. The requirement of concrete property indices is than clearer and more definite, refinement and concrete in the past. Meanwhile, the lifting of Architectural Equipment level, continuing to bring out and promoting of novel construction process, makes concrete technology adapt to different designs, construction and instructions for use, develops very fast.

Concrete also be unable to do without the raw-material development of the reinforcement of concrete, be unable to do without the development and change of concrete engineering application. Therefore, development performance is more excellent, function is more powerful, more adapt to new technology, the concrete of new building object just seems particularly important.
