Description
Technical field
The present invention relates to chemical field, specifically a kind of new template self-compacting concrete viscosity modifiers of CRTS III
Material.
Background technology
The plate-type non-fragment orbits of CRTS III are that, by a kind of new-type non-fragment orbit of China's independent research, it is different from CRTS I
Type and the type non-fragment orbits of CRTS II, it is not necessary to using cement emulsified asphalt mortar as packed layer, but use have it is good and
Yi Xing, mechanics insensitive to environment temperature and excellent and the self-compacting concrete of durability.III template is from close at this stage
There is following some inferior position in the viscosity modifying material used in real concrete：1st, can not effectively solve concrete mix and easy
Property is poor, the problems such as bleeding, bleeding easily occurs, simply increases the mobility of concrete mix, but other state performances
It is poor.2nd, the quality requirement to concrete raw material is very high, and the quality fluctuation of raw material is easy to cause the performance ripple of concrete
It is dynamic.3rd, operable time is shorter, and haul distance site operation more long is difficult.
The content of the invention
In order to avoid the weak point that prior art is present, the present invention provides a kind of new template self-compactions of CRTS III and mixes
Solidifying soil viscosity modifying material.
The present invention solves technical problem and adopts the following technical scheme that：
A kind of template self-compacting concrete viscosity modifying materials of CRTS III, it is characterised in that the material modified group in mass ratio
Into as follows：
Flyash 45-60%；
Super finely ground slag 40-60%；
Redispersable latex powder 0-5%；
The glutinous type hydroxypropyl methyl cellulose 0~5% of height.
Preferably, the material modified component is as follows：
Flyash 40%
Super finely ground slag 55%
Redispersable latex powder 3%
The glutinous type hydroxypropyl methyl cellulose 2% of height.
Preferably, the material modified component is as follows：
Flyash 45%
Super finely ground slag 50%
Redispersable latex powder 3%
The glutinous type hydroxypropyl methyl cellulose 2% of height.
Preferably, the material modified component is as follows：
Flyash 50%
Super finely ground slag 45%
Redispersable latex powder 3%
The glutinous type hydroxypropyl methyl cellulose 2% of height
Further, the loss on ignition of the flyash is less than 3%.
Compared with the prior art, the present invention has the beneficial effect that：
Viscosity modifying material of the present invention can solve its isolation, secrete on the premise of self-compact concrete in construction performance is not changed
The problems such as water, surface laitance, eliminate self-compacting concrete perfusion after some foams, laitance layer, it is ensured that packed layer with it is upper
The adhesion strength of layer track plates, improves the durability of structure.
2nd, the active ingredient in viscosity modifying material of the present invention has held the bubble layer in concrete mix well, makes
Mobility, autgmentability it is more excellent.
3rd, the high-performance miberal powder and flyash in viscosity modifying material of the present invention can improve the work of concrete mix
Time, site operation more facilitates.
4th, the present invention is preferable to each raw material adaptability of concrete, and a little fluctuation of raw material quality will not be to whole coagulation
The performance of native mixture produces influence.
