The raw material that above-mentioned disclosed the reinforcement of concrete shrinkage type water reducer has is complicated, and cost is higher, have through the impervious effect of overtesting be not fine.
Summary of the invention
In view of the deficiency that above-mentioned prior art exists, the object of this invention is to provide a kind ofly significantly improve impermeability, reducing property, impermeability, large, water-repellancy, closely knit effect the Anti-permeation concrete of water-reducing rate reduce diminishing waterproof compacting agent, and only need add this product repeatedly need not add admixture in concrete.Product is liquid, is convenient to add, and low alkalinity, does not corrode, without inflammable and explosive property, and nontoxicity.
The object of the present invention is achieved like this:
A kind of Anti-permeation concrete reduces diminishing waterproof compacting agent, and it comprises the raw material of following parts by weight, and wherein, it comprises the raw material of following parts by weight, wherein, and high-performance polycarboxylic acids water reducing agent 48-54 part; Iron trichloride 13-21 part; Sunmorl N 60S 5-10 part; Sucrose 3-5 part; Water 10-15 part; Also comprise the defoamer of 0.05-0.5 part and the air entrapment agent of 0.1-2.0 part.
Described high-performance polycarboxylic acids water reducing agent is polyester type structure; Or polyether-type structure; Solid content is 40%.
Described defoamer is silicone oil.
Described air entrapment agent is black liquid and molasses reaction solution, and its preparation method is: solid content is that the strong sulfuric acid response 0.5-1 hour that black liquid weight 1 part and the cane molasses weight 1 part of 30-60% adds the 70-90% of weight 1 part obtains.
Anti-permeation concrete of the present invention reduces the production method of diminishing waterproof compacting agent, first iron trichloride is put into water, make it to be dissolved in the water completely under whipped state, allow after its naturally cooling and add Sunmorl N 60S and sucrose, add high-performance polycarboxylic acids water reducing agent again, mix, enter in finished product packing tank, test package, obtains product.
Anti-permeation concrete of the present invention reduces the production method of diminishing waterproof compacting agent, also can be first iron trichloride is put into water, make it to be dissolved in the water completely under whipped state, allow after its naturally cooling and add Sunmorl N 60S and sucrose, add high-performance polycarboxylic acids water reducing agent again, finally add air entrapment agent and defoamer mixes, enter in finished product packing tank, test package, obtains product.
High-performance polycarboxylic acids water reducing agent of the present invention (PolycarboxylateSuperplasticizer), it is a kind of cement dispersants during cement concrete uses, the present invention adopts the high-performance polycarboxylic acids water reducing agent of two types, a kind of is methacrylic acid with main chain, side chain is hydroxy-acid group and MPEG (Methoxypolyethyleneglycol), polyester type structure; Another for main chain be polyacrylic acid, side chain is Vinylalcoholpolyethyleneglycol, polyether-type structure; The solid content of high-performance polycarboxylic acids water reducing agent is 40%.
Anti-permeation concrete of the present invention reduces the beneficial effect of diminishing waterproof compacting agent:
1, can significantly improve that impermeability, reducing property, impermeability, water-reducing rate are large, water-repellancy, closely knit effect.In concrete, only need add this product need not repeatedly add other admixture.Product is that liquid is convenient to interpolation and can is effectively stoped water molecules to permeate, significantly improve intensity, impervious rank reaches 12 grades, can make to bond between concrete particle more closely and form parcel and reach impervious while can reduce contraction more than 30%, especially in the presence of a harsh environment, can reduce contraction, this is very important for effectively controlling cracking; Volume can be increased and decreased as requested.This product, by different labels concrete and different slump requirement, recommends volume to be the 0.21%-0.22% of gelling material, and detecting volume is 0.21% of gelling material.It is a kind of compound product, has several functions.
2, the air entrapment agent selected of the present invention and defoamer effect good, particularly adopt black liquid and molasses reaction solution, cost is low, can carry out utilization of waste material.Containing a large amount of xylogen in black liquid, can obtain resisting the material that water molecules permeate after adding sulfuric acid reaction with molasses, make concrete produce certain dope in addition, be not easy to ftracture.
