Description
Technical field
The present invention relates to building material field, be specifically related to one and can be used for pump concrete anti-crack water-proof agent.
Background technology
In various construction, to use concrete in a large number, in cast Concrete, cracking is insoluble problem always in construction quality, its long-standing problem each construction and uses unit, and have influence on the normal use of building, and concrete service life can be decreased because of cracking, since alleviating a large amount of commodity in use concrete (ready-mixed concrete) of municipal pollution, even more serious through the distress in concrete phenomenon of long distance delivery.In order to solve the technical barrier of this long-standing problem, insider is through long-term practice and gropes, have found the principal element of concrete cracking and cause due to metamorphosis, deformation includes: temperature deformation, contraction distortion and foundation settlement deformation etc., concrete cracking will be caused after these deform more than the tensile strength of concrete pre-stress, therefore only solve these deformation concrete and could fundamentally solve concrete problem of Cracking.
Rigid material waterproof is mainly the extender based on inorganic material and the composite water-proof agent being made up of Organic substance and inorganic matter.The disadvantages such as existence volume all in various degree is big, maintenance is difficult for they, alkali total amount height, bad adaptability, function are restricted.Use rear concrete to there will be the different plugging of degree, be difficult to pumping, setting time is difficult to control to and dry shrinkage and cracking and Seepage.
Summary of the invention
It is an object of the invention to overcome the deficiency of above-mentioned waterproofing agent, there is provided one can dramatically increase mortar, concrete early strength, increase mobility, improve guarantor and mould ability, being suitable for the waterproofing agent of pump concrete, the present invention can be used for underground engineering, dykes and dams, architectural engineering, the waterproof mortar of traffic engineering and water-proof concrete etc. simultaneously.
For achieving the above object, the present invention adopts the following technical scheme that
