Description
Technical field
The present invention relates to concrete for making technical fields, and in particular to a kind of construction material concrete of environmental protection and its preparation
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 is gradually increased, 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 construction 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 using space, and compared to other materials, there is relatively low cost, with
The development of China's high-rise building, for super high strength concrete demand also in growth gradually.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.
Deficiency for the poor thermal insulation property for improving normal concrete, building inside/outside closed structure need 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 making, 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 whole 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 novel 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 best replacement of organic combustible material.At present, foam concrete
In the application of every field there is no being widely used to promote, 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 under the precondition for reducing foam concrete dry density, how to improve its compression strength and balance foam coagulation
Other performances of soil.
