Economic continuous development has driven construction industry rapid development, and concrete is maximum as modern construction engineering dosage
One of construction material, the growth that the demand in all kinds of buildings is advanced by leaps and bounds.
As concrete must one of additive dosage of gathering materials it is very big, natural aggregate exhaustive exploitation, be allowed to quality also without
Method meets the needs of existing concrete production, at present concrete there is also intensity difference, frost resistance it is low, it is dry shrink big, easily occur
The deficiencies of cracking.
In recent years, with the improvement of living standards and social progress, people's daily life and industrial processes generate
Various solid wastes and urban construction removal remake bring solid waste etc. and annoying the living environment of resident always, more not
The processing that can continue the waste and old clothes worn is always a difficult problem, and current high buildings and large mansions are constantly emerging always, building knot
The fire problem of structure becomes increasingly conspicuous.In all kinds of fire, frequency is most, loss most serious person surely belongs to building and catches fire.It is mixed
Solidifying soil is the maximum construction material of dosage in current civil engineering, and concrete structure is the primary structure form of building, therefore,
The high-temperature behavior of concrete is most important to the fire-resistance behavior of building.The concrete of inside solid is acted on by high temperature of fire
When can occur seriously to burst, be subjected to concrete mechanics and endurance quality serious deterioration after high temperature, not only threaten structure safety, it is also right
Human life's property safety causes imponderable damage.
