5%.
On that basis of the above technical scheme: it according to mass parts ratio is 35 that the retarder, which is sodium gluconate and citric acid,
The ratio of~50%:65~50% compounds gained.
On that basis of the above technical scheme: the water-retaining agent is technical grade hydroxypropyl methyl cellulose.
On that basis of the above technical scheme: the consistency modifiers are polyacrylamide.
On that basis of the above technical scheme: the filler is one or both of flyash and ordinary portland cement.
On that basis of the above technical scheme: the colorant is inorganic pigment.
On that basis of the above technical scheme: the inorganic pigment is iron oxide red.
On that basis of the above technical scheme: the preparation side of the cleaning agent for undisguisedly expecting pervious concrete cleaning
Method mainly includes the following steps that,
A. above-mentioned raw materials are weighed by mass percentage, and addition is prepared in vessel and stirred with 500rpm/min revolving speed
It mixes, forms finely dispersed mixture；
B. in use, the water of mixture quality 100~200% is added into mixture, stirring obtains dew in 1~2 minute
Aggregate pervious concrete cleaning agent.
On that basis of the above technical scheme: the application method of the cleaning agent for undisguisedly expecting pervious concrete cleaning
For after pervious concrete moulding by casting, the cleaning agent is sprayed at concrete surface immediately and covers membrane curing immediately, 24
Concrete surface is rinsed with water after~48h.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are: the present invention is to environment applicable for temperature
It is big to spend range, fountain height fluctuation susceptibility is low, and easy coloring, depth of penetration is easily-controllable, and the controllable time is long, is able to achieve good surface
Undisguised effect.
