Fast concrete repair additives of accelerating admixture

Fast concrete repair additives of accelerating 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 concretework with quick setting requirements (plugging , rapid repair, etc.).

The technical performance of Accelerating admixture as follows:

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.

   High early strength concrete superplasticizer with mixing naphthalene,

Composite antifreezing agent concrete water reducing agent,

Export polycarboxylate superplasticizer concrete additives,

and other products.
