Description

A kind of easily and concrete and preparation method thereof

Technical field

The invention belongs to building material field, particularly one easily and concrete and preparation method thereof.

Background technology

Concrete has abundant raw material, cheap, the simple feature of production technique, thus makes its consumption increasing.Simultaneously also to have ultimate compression strength high for concrete, good endurance, the features such as strength grade wide ranges.These features make its use range very extensive, and not only using in various civil engineering work, is exactly shipbuilding, mechanical industry, the exploitation of ocean, geothermal engineering etc., and concrete is also important material.

Along with the development of component materials of concrete, people are not only confined to ultimate compression strength to concrete performance requriements, but on the basis basing oneself upon intensity, more focus on concrete weather resistance, deformation performance, fire-and explosion-proof performance, water-impervious performance, toughness, erosion resistance, heat retaining property, health environment-friendly and to reduce costs etc. the balance and coordination of overall target.The requirement of concrete property indices is than clearer and more definite, refinement in the past and concrete.Meanwhile, the lifting of Architectural Equipment level, the continuing to bring out and promoting of novel construction process, concrete technology is adapted to different designs, construction and service requirements, 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 engineer applied object.Therefore, develop that performance is more excellent, function is more powerful, more adapt to novel process, the concrete of new building object just seems particularly important.
