Description
Technical field
The invention belongs to building material technical field, more particularly to a kind of new concrete additive.
Background technology
Concrete referred to as " concrete ", typically refers to make cementitious material with cement, sand, masonry gather materials, with water by a certain percentage
Cooperation, agitated gained.The characteristics of concrete has abundant raw material, cheap, simple production process, makes its use scope ten
Divide extensively, not only used in various civil engineerings, be exactly shipbuilding industry, mechanical industry, the exploitation of ocean, geothermal engineering etc., mix
Solidifying soil is also important material.But concrete material is due to the characteristic of self structure, in use especially for those
Underground and aouatic structure engineering are often present with Seepage, this seriously affects and constrain the application of concrete material.
Therefore, constantly it is suggested in relation to improving and improving the various additives of concrete material impermeability, such as early stage
Some expand the inorganic water-proof agents such as calcium chloride, the iron chloride to improve concrete anticracking impermeability by generation, in addition with
Some organics, such as organosilicon, aliphatic acid；But these waterproofing agent one side waterproof abilities are limited, it is impossible to persistently.
Therefore, some new more effective waterproof additives are expected by development and application.
The content of the invention
It can make concrete anticracking, anti-permeability performance enhancing the technical problem to be solved in the present invention is to provide one kind and can improve pair
The new concrete additive of the waterproofing protection phase of building.
In order to solve the above technical problems, the technical scheme is that：A kind of new concrete additive, innovative point exist
In：The new concrete additive is made of the component of following parts by weight：12-16 parts of sodium carboxymethylcellulose, aluminum sulfate
1-3 parts of 20-30 parts, 4-6 parts of oxide powder and zinc, 4-6 parts of activated carbon, 60-70 parts of polyester fiber and dispersant；Wherein, it is described scattered
Agent is mixed by neopelex and calcium stearate, and neopelex and calcium stearate mass ratio
For 1.3-1.7:1.
Further, the granularity of the oxide powder and zinc is 400-600 mesh.
Further, the activated carbon choice of powder shape, granularity are 200-400 mesh.
Further, the polyester fiber, the length of 10-14mm, a diameter of 22-26 μm.
The advantage of the invention is that：New concrete additive of the present invention, can make concrete anticracking, anti-permeability performance enhancing and
The waterproofing protection phase to building can be improved.
