Description
Technical field
The present invention relates to technical field of concrete additives, particularly to a kind of Concrete synergist.
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 a kind of Concrete synergist, it is possible to increase the intensity of concrete,
Make the abundant aquation of cement, save cement consumption.
For achieving the above object, technical scheme to be solved by this invention is:
The present invention provides Concrete synergist, is made up of the raw material of following weight portion: triisopropanolamine 40～80 parts, wooden
Element sodium sulfonate 5～15 parts, tea saponin 1～10 parts, sugar refinery waste liquid 1～5 parts, ethyl acetate 0.2～1.8 parts, Redispersable latex
Powder 0.1～0.9 part.
Preferably, Concrete synergist of the present invention, be made up of the raw material of following weight portion: triisopropanolamine 50～
70 parts, sodium lignin sulfonate 8～12 parts, tea saponin 3～7 parts, sugar refinery waste liquid 1～3 parts, ethyl acetate 0.6～1.4 parts, can be again
Dispersed latex powder 0.3～0.5 part.
It is highly preferred that Concrete synergist of the present invention, it is made up of the raw material of following weight portion: triisopropanolamine 60
Part, sodium lignin sulfonate 10 parts, tea saponin 5 parts, sugar refinery waste liquid 2 parts, ethyl acetate 2 parts, redispersable latex powder 0.4 part.
Preferably, Concrete synergist of the present invention also includes propylene glycol 5～21 weight portion.The end group of propylene glycol is
One aliphatic group, has the mobility of preferable dispersibility, beneficially powder body, and propylene glycol coordinates with triisopropanolamine and has relatively
Good grinding-aid effect, and the consumption of triisopropanolamine can be reduced, additionally it is possible to improve the intensity of grinding aid.
Preferably, Concrete synergist of the present invention also includes propylene glycol 13 weight portion.
The Concrete synergist of the present invention volume in concrete is according to the volume of prior art.
In the raw material of the present invention, the triisopropanolamine of the present invention is as early strength agent, it is ensured that the intensity of concrete, simultaneously and its
Its raw material coordinates the adaptability that can also improve synergist with various cement；Sodium lignin sulfonate has diminishing, slow setting, bleed three concurrently
Weight effect, can play the effect improving concrete parcel performance, improve concrete slump gradual loss problem faster, with
Time can improve anti-thawing ability and the durability of concrete；Tea saponin belongs to triterpenoid saponin, is the non-of a kind of function admirable
Ion-type pure natural surfactant, it has the effects such as stronger foaming, emulsifying, dispersion, moistening, and is little affected by water quality
The impact of hardness, it bubbles fast, and amount of air entrainment is relatively large, and can improve bubble further stably with sodium lignin sulfonate compatibility
Property, concrete durability；Sugar refinery waste liquid and sodium lignin sulfonate can preferably improve concrete workability, reduce cement consumption；Second
Acetoacetic ester has the most slow corrosiveness, protects reinforcing bar；Redispersable latex powder can improve the rupture strength of concrete, aobvious
Work improves concrete slump gradual loss problem faster.
Compared with prior art, the beneficial effects of the present invention is:
1, the Concrete synergist of the present invention can not normally play in can making generally concrete effect 20～
The 30% abundant aquation of cement, improves concrete parcel performance, and significantly improves concrete slump gradual loss problem faster.
2, the Concrete synergist of the present invention saves cement consumption 10～about 15%, and it is strong to improve agent on crack resistance of concrete folding
Degree can improve 5～10%, 7d and 28d compressive strength rate is all more than 90%.
3, the Concrete synergist of the present invention makes concrete have good durability, compared with normal concrete, to durable
Property index is calculated as 94% with the dynamic modulus of elasticity retention of 200 times, and durability loss is less.
4, the Concrete synergist of the present invention makes concrete have good cryoprotective effects, through measuring, and freeze thawing resistance circulation time
Number can reach more than 250 times.
5, the Concrete synergist of the present invention makes concrete water bleeding rate significantly reduce, and water-reducing rate significantly improves, through testing, with
Normal concrete is compared, and water-reducing rate is more than 6%, and bleeding rate reduces by 48%.
6, the Concrete synergist strong adaptability of the present invention, is suitable for various concrete.
7, the Concrete synergist of the present invention has the most slow corrosiveness, makes concrete to reinforcing bar non-corrosiveness, protects
Protect reinforcing bar.
