Description
Technical field
The present invention relates to concrete for making technical field, and in particular to a kind of composite concrete for building and its preparation side
Method.
Background technology
In recent years, high strengthening becomes one of trend of modern concrete technology development.The research of high-strength concrete, exploitation work
Larger progress is achieved, the intensity of high-strength concrete gradually steps up, performance constantly improve, and is obtained in many fields
Extensive use.But as the complication of building structure, high-rise building are increasing, high-strength concrete can not meet to build need
Will, the main trend that super high strength concrete will develop as concrete.Countries in the world start to carry out super high strength concrete
Theoretical research and engineer application.
Super high strength concrete is a kind of good structural material, it possesses high intensity and excellent endurance quality, can
Effectively to lower dead load, increase building uses space, and compared to other materials, has relatively low cost, with
The development of China's high-rise building, for super high strength concrete demand also in growth progressively.As modern architecture is towards height
Stratification, large span, lightweight, ruthless area development（Cold district, varieties in saline-alkali areas）Requirement to concrete strength is also got over
Come it is higher, therefore carry out develop high-strength high-performance concrete have important practical significance.
To improve the deficiency of the poor thermal insulation property of normal concrete, building inside/outside closed structure needs to add insulating layer.Tradition
Thermal insulation material is organic insulation material, and environmental pollution is serious and inflammable, easy to aging, durability is poor when it makes, and various regions are protected
Warm architectural engineering repeated fire incident, and organic insulation material will soon be melted in fire, and smog is big, toxicity is big, very
Difficulty is puted out a fire to save life and property, and harm is serious.The fire safety problem of wall heat insulation material is not solved, the Energy Conservation Project in Construction in China will have great
Fire hazard, this causes inorganic heat insulation material substitution organic insulation material to become the certainty of historical development and scientific and technological progress.2009
The Nian9Yue20 Ministry of Public Security and the firmly portion's of building joint promulgate public affairs [2009] No. 46 texts of logical word《Civil buildings outer heat preservation system and exterior wall dress
Decorations fire prevention temporary provisions》, specific requirement is proposed to civil buildings wall thermal insulation material combustibility rank and fireproof construction.Root
According to regulation, the overall exterior walls of civil buildings must use A-grade non-ignitable heat insulating material, and there is an urgent need to not only energy saving but also with resistance in market
Fire the building space enclosing structure material, product and its system of contour performance.
Foam concrete is as new inorganic fireproofing insulation material, and generally existing density is big, and intensity is low and heat insulating ability is too late
The defects of organic material, but synthesis is compared, it is still the optimal replacement of organic combustible material.At present, foam concrete
Use is not widely popularized in the application of every field, mainly due to dry density and compression strength problem.Because foam
Coagulation filling's dry density and compression strength index are mutually contradictory, are unity of contradictions bodies.And domestic main research is weight
Point is solved in the case where reducing the precondition of foam concrete dry density, how to improve its compression strength, and balance foam coagulation
Other performances of soil.
The content of the invention

The defects of degree is unmanageable, and intensity is low；The resistance to compression of concrete, anti-folding, tensile strength are added, adds corrosion resistance, antirust
Performance, waterproof, seepage control performance.
The structure that concrete one-piece casting of the present invention forms is than the common insulation construction for gluing, hanging, the mode construction such as smearing
It is more safe and reliable on the whole, it can effectively avoid other insulation energy-saving systems from protective layer cracking easily occur and be taken off with finish coat
Situation about falling, while can also prevent that heat-insulation system from being wiped off by strong wind and rainwater is oozed to exterior wall inner surface.
Waterglass has higher activity and is loose structure, under the selected moderate dosage of the present invention, with higher
Activity improves the later strength of concrete；Meanwhile waterglass plays the role of storage reservoir in concrete, be conducive to carry
High concrete internal relative humidity, reduces the self-constriction of super high strength concrete.
