Abstract
The invention belongs to technical field of concrete additives, particularly to a kind of synergist for concrete, it is made up of the raw material of following weight portion: diethanol monoisopropanolamine 60～100 parts, poly carboxylic acid series water reducer 20～40 parts, polyvinyl alcohol 15～31 parts, sodium thiosulfate 5～21 parts, fumaric acid 1～8 parts, sodium tripolyphosphate 0.3～1.5 parts.The present invention can significantly improve the parcel of concrete for the synergist of concrete, makes the abundant aquation of cement, reduces cement consumption, increases substantially workability and the homogeneity of concrete, and bleeding is greatly decreased, and has superpower adaptability with various cement.
Description
Technical field
The invention belongs to technical field of concrete additives, particularly to a kind of synergist for concrete.
Background technology
Concrete is to be gathered materials (also referred to as aggregate) by cement cementitious material, graininess and water is prepared by a certain percentage, through all
Even stirring, closely knit molding, a kind of artificial stone material of maintenance hardening.It has abundant raw material, cheap, production technology letter
Single feature, is one of contemporary topmost civil engineering material.Also to have comprcssive strength high for concrete simultaneously, good endurance,
The features such as strength grade wide ranges.These features make its range quite varied, not only use in various civil engineerings, just
Being shipbuilding industry, mechanical industry, the exploitation of ocean, geothermal engineering etc., concrete is also important material.Concrete is the most large
Artificial stone, has the status that other any construction materials are not replaced, and the appearance of concrete admixture and development is to coagulation
Soil technological innovation has the meaning of milestone especially, it has also become in concrete in addition to cement, water, Binder Materials and admixture
Indispensable BSA.But, hydrated cementitious degree research data is shown by domestic and international concrete, under conventional environment,
Concrete there are about 20～30% cement do not participate in hydration reaction, the most normally play effect, be maximum in concrete application
Cost waste.Main cause be concrete in whipping process, cement can not effectively be disperseed, and chemical reaction does not occurs, and
Become cement more than needed.
Concrete synergist is a kind of novel concrete admixture, can make the abundant aquation of cement, saves cement consumption 10
～about 15%, improve the workability of concrete, the intensity improving concrete and durability, to concrete associated production simultaneously
Enterprise brings energy-saving and cost-reducing, to reduce a series of sustainable developments such as environmental pollution advantage.At present, Concrete synergist on the market
Product category is less, there will be the problems such as concrete parcel property is bad, Slump Time losing of Large is very fast, cause mixing in application process
Solidifying soil synergist fails to obtain the most extensively application.
Summary of the invention
The technical problem to be solved is to provide the synergist for concrete, and it can significantly improve concrete
Parcel, make the abundant aquation of cement, reduce cement consumption, increase substantially workability and the homogeneity of concrete, bleeding is big
Width reduces, and has superpower adaptability with various cement.
For achieving the above object, technical scheme to be solved by this invention is:
The present invention provides a kind of synergist for concrete, is made up of the raw material of following weight portion: diethanol list isopropyl
Hydramine 60～100 parts, poly carboxylic acid series water reducer 20～40 parts, polyvinyl alcohol 15～31 parts, sodium thiosulfate 5～21 parts, rich horse
Acid 1～8 part, sodium tripolyphosphate 0.3～1.5 parts, water 50～90 parts.
Preferably, the synergist for concrete of the present invention, it is made up of the raw material of following weight portion: diethanol list
Isopropanolamine 70 parts, poly carboxylic acid series water reducer 35 parts, polyvinyl alcohol 19 parts, 18 parts of sodium thiosulfate, fumaric acid 1 part, trimerization phosphorus
1.2 parts of sodium of acid, 60 parts of water.
Preferably, the synergist for concrete of the present invention, it is made up of the raw material of following weight portion: diethanol list
Isopropanolamine 80 parts, poly carboxylic acid series water reducer 30 parts, polyvinyl alcohol 23 parts, 13 parts of sodium thiosulfate, fumaric acid 2 parts, trimerization phosphorus
0.9 part of sodium of acid, 70 parts of water.
Preferably, the synergist for concrete of the present invention, it is made up of the raw material of following weight portion: diethanol list
Isopropanolamine 90 parts, poly carboxylic acid series water reducer 25 parts, polyvinyl alcohol 27 parts, 9 parts of sodium thiosulfate, fumaric acid 5 parts, tripolyphosphate
0.6 part of sodium, 80 parts of water.
Preferably, the synergist for concrete of the present invention, it is made up of the raw material of following weight portion: diethanol list
Isopropanolamine 100 parts, poly carboxylic acid series water reducer 20 parts, polyvinyl alcohol 31 parts, 5 parts of sodium thiosulfate, fumaric acid 6 parts, trimerization phosphorus
0.3 part of sodium of acid, 90 parts of water.
Compared to existing technology, the beneficial effects of the present invention is:
1, the present invention can significantly improve the parcel of concrete for the synergist of concrete, and significantly improves concrete
Slump Time losing of Large problem faster, makes normally to play the 20 of effect～30% abundant aquation of cement, reduces cement and use
Amount 10～about 15%.
2, the present invention increases substantially workability and the homogeneity of concrete for the synergist of concrete, and bleeding significantly subtracts
Few, with various cement, there is superpower adaptability.
3, improve the density of concrete, improve impermeability, reduce concrete crack.
4, the synergist for concrete of the present invention makes concrete have good durability, compared with normal concrete,
With the dynamic modulus of elasticity retention of 200 times, durability index is calculated as 96%, and durability loss is less.
5, the synergist for concrete of the present invention makes concrete have good cryoprotective effects, through measuring, and freeze thawing resistance
Cycle-index can reach more than 250 times.
Improve the strength grade of concrete,
