High Quality Concrete Accelerator Concrete Admixture
High quality concrete accelerator chemical admixture is a new type of high efficient accelerator
developed by Qingdao Hongsha polymer materials Co., Lt, its technical performance and
economic benefits is superior to the similar products in domestic market, and it is widely used in
spray concrete engineering such as railway and highway, tunnel, coal mine roadway, hydropower,
and other concrete work with quick setting requirements (plugging , rapid repair, etc.).
The technical performance of High quality concrete accelerator chemical admixture as follows:
Appearance | Gray powder | |
Dosage | 4-6% powder | |
Setting time(min) | Initial setting | 5max |
Final setting | 10max | |
Compressive strength | 1d( Mpa) | 6min |
28d(%) | 75min (conform to the index of "sprayed concrete accelerator" JC477-2005 ) | |
Property | Weakly alkaline, non-toxic, non-flammable, non-chlorine salt, no corrosive effect on steel | |
Spray concrete with this product has small loss of the later strength, and low resilient rate, a jet of highthickness, is conducive to improve the quality and durability of concrete spray engineering,
has obvious technical and economic benefit.
Construction requirements:
1.For in-field use,do anti-corrosion measures, accurate measurement, and the powder after
opening the packing should be used once, the liquid shall be sealed.
2.When sprayed concrete construction should use the new factory portland cement, ordinary portland cement, slag portland cement, if the cement expired, moisture caking, low ambient temperature, it willaffect the results.
3.Shotcrete should adopt the maximum particle diameter of not less than 20mm of gravel or crushed stone, sand fineness modulus 2.8-3.5.
1.Its technical performance and economic benefits is superior to the similar products in domestic
market.
2.It is widely used in spray concrete engineering such as railway and highway, tunnel, coal mine roadway, hydropower , and other concrete work with quick setting requirements (plugging , rapid repair,
etc.).
3.Small loss of the later strength.
4.Low resilient rate.
5.A jet of high thickness.
6.Improve the quality and durability of concrete spray engineering.
7.Has obvious technical and economic benefit.
