Shotcrete Accelerator, MNC-Q2 Type

MNC-Q2 type shotcrete accelerator is new generation of highly active and environment-friendly liquid accelerator with no chlorine and no alkali, adopting advanced foreign technology and new process synthesized by organic and inorganic materials. It is widely used in various projects on the production process of wet spray method.

Our shotcrete accelerator has no harm to human body and no erosion to steel bars, and it can also significantly promote the development of cement hydration and concrete strength with good adaptability to different cement, good workability, homogeneity, almost no loss of concrete strength and no dust on working face. The performance index of our product has reached or exceeded the international standard of the same brand. Also, shotcrete accelerator has received a leading position among the domestic similar products.

Main Technical Performance
1. Shotcrete accelerator has fast setting time. Initial setting time ranges from 2 to 5 minutes and final setting time ranges from 3 to 10 minutes.
2. It has good adhesion with the spray layer up to 8 to 150 mm.
3. Its springback generally amounts to 5% to 10%.

Dosage range
Dosage of shotcrete accelerator ranges from 3% to 8% of the weight of cementing material and it can replace water in the same amount. Its actual content should be decided by the cement type, grade and the adjustment of construction temperature.

Other Products
  • PCL Polycarboxylate Superplasticizer Concrete AdmixturePCL polycarboxylate superplasticizer concrete admixture features good stability especially at low temperature. Besides, the liquid concentration of our product can be diluted from 50% to 10% and then you can directly use the diluted product as pumping admixture of mixing plant.
  • FDN Naphthalene Sulfonate Formaldehyde Condensate Concrete AdmixtureCompared with UNF-5 type, FDN naphthalene sulfonate formaldehyde condensate concrete admixture has higher water reducing rate and fewer concrete slump loss, which can efficiently increase the concrete fluidity, reduce bleeding and segregation and then improve the workability of concrete.
