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 by a certain percentage
Preparation, through uniform stirring, closely knit shaping, a kind of artificial stone material of maintenance hardening.It has former
Material is abundant, and cheap, the simple feature of production technology, is contemporary topmost civil engineering material
One of.Concrete also has the features such as compression strength height, good endurance, strength grade wide ranges simultaneously.
These features make its range quite varied, not only use in various civil engineerings, it is simply that shipbuilding
Industry, mechanical industry, the exploitation of ocean, geothermal engineering etc., concrete is also important material.
Research shows, under natural environment, has the cement of nearly 20% not have complete water in matured concrete
Change, simply play filling effect.Main cause be concrete in whipping process, cement can not be had
, there is not chemical reaction, and become cement more than needed in effect dispersion.How to play this part to have more than needed cement
Effect, become the popular research of this area.
Summary of the invention
The technical problem to be solved is to provide a kind of Concrete synergist, and this synergist improves
The compression strength of concrete and rupture strength, and have efficiently excite water reducer and high efficiency dispersion gelling material
Effect of material, can improve concrete workability, and anti-bleeding isolates, and reduces distress in concrete, freeze thawing resistance
It is improved with resisting carbonization.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of Concrete synergist, is made up of the raw material of following percentage by weight:
Preferably, the Concrete synergist of the present invention, it is made up of the raw material of following percentage by weight:
Poly carboxylic acid series water reducer described above is acrylic compounds, methacrylic or maleic acid anhydride
Poly carboxylic acid series water reducer.
Preferably, poly carboxylic acid series water reducer described above is acrylic compounds poly carboxylic acid series water reducer.
In the Concrete synergist formula of the present invention, each component has well played cooperative effect, wherein,
Triethanolamine can improve early strength and the unit-hour output of concrete, incorporation is suitable, it is to avoid mixes
Measure and too high later stage concrete is had a negative impact；Carboxylic propyl methocel has the strongest dispersiveness
Can, also there is water-retaining property, water reducer and dispersion agent gel material can be excited efficiently；Polyacrylamide has
There is lubrication, reduce the resistance ground, reduce pumping frictional resistance, improve the mobility of concrete；Poly-
Carboxylic acid water reducing agent plays minimizing solidifying soil mixing water, promotes concrete early strength agent, micro-air-entraining effect, carries
High concrete freeze thawing resistance and resisting carbonization；It is triple that sodium lignin sulfonate has diminishing, slow setting, bleed concurrently
Effect, can play the effect improving concrete parcel performance, can improve agent on crack resistance of concrete carbonization simultaneously
Ability；Silicon ash can the intergranular hole of filling concrete, generate gelinite, tool with hydrated product simultaneously
Be significantly improved the effect of concrete strength, adds appropriate silicon ash and can improve strength grade of concrete；
Sodium tripolyphosphate can improve the early strength of concrete；Neopelex significantly solves synergy
Agent and the adaptability problem of concrete；Sodium gluconate can significantly improve the mobility of concrete, promotees
Enter the refinement of concrete.
Having the beneficial effects that in the present invention:
1, being effectively improved the workability of concrete, reduce bleeding, pumping frictional resistance is little.
2, improve the density of concrete, improve impermeability, reduce concrete crack.
3, cement consumption 12～17% can be reduced, can keep or exceed reference intensity.
4, water reducer and dispersion agent gel material can be excited to greatest extent.
5, nontoxic pollution-free of the present invention, produces zero-emission, belongs to green material.
