Abstract
The present invention relates to a kind of concrete additive, the concrete additive is made up of the component of following parts by weight：35 parts of 10 16 parts of sodium carboxymethylcellulose, 20 30 parts of aluminum sulfate, 46 parts of oxide powder and zinc, 46 parts of activated carbon, 60 70 parts of polyester fiber and dispersant.The advantage of the invention is that：Concrete additive of the present invention, concrete anticracking, anti-permeability performance enhancing can be made and can be improved the waterproofing protection phase to building.
Description
Technical field
The invention belongs to building material technical field, more particularly to a kind of concrete additive.
Background technology
Concrete, referred to as " concrete ", typically refer to make binder materials with cement, sand, masonry gather materials, with water by a certain percentage
Coordinate, agitated gained.Concrete has abundant raw material, cheap, the characteristics of simple production process, makes its use range 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 and important material.But concrete material is due to the characteristic of self structure, in use especially for those
Seepage often occurs in underground and aouatic structure engineering, and this has a strong impact on and constrained the application of concrete material.
Therefore, constantly it is suggested about improving and improving the various additives of concrete material impermeability, such as early stage
Some are expanded to improve the inorganic water-proof agents such as the calcium chloride of concrete anticracking impermeability, iron chloride by producing, 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 effectively waterproof additives are expected to be developed and apply.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind can make concrete anticracking, anti-permeability performance
Strengthen and the concrete additive to the waterproofing protection phase of building can be improved.
In order to solve the above technical problems, the technical scheme is that：A kind of concrete additive, its innovative point are：
The concrete additive is made up of the component of following parts by weight：Sodium carboxymethylcellulose 10-16 parts, aluminum sulfate 20-30 parts,
Oxide powder and zinc 4-6 parts, activated carbon 4-6 parts, polyester fiber 60-70 parts and dispersant 3-5 parts.
Further, the granularity of the oxide powder and zinc is 400-600 mesh.
Further, the activated carbon choice of powder shape, its granularity are 200-400 mesh.
Further, the polyester fiber, its length are 10-14mm, a diameter of 22-26 μm.
Further, the dispersant selects neopelex.
The advantage of the invention is that：Concrete additive of the present invention, concrete anticracking can be made, resisted
Ooze performance enhancement and can improve the waterproofing protection phase to building.
