Introduction of ZC-2 Cement Accelerator:
Model ZC-2 cement accelerator is an additive used to speed the setting and hardening of cement, mortar and concrete, especially shortcrete.
It is used for road tunnels, rail tunnel, shafts/ drifts and excavations in all mines and other underground engineering such as hydroelectricity, military industry and civil air defense etc, also suitable for civil construction projects which are required to commission as early as possible and to quicken the solidifying and hardening of ground surface.
It has passed the test of Sudbury Lad in Canada.
Features fo ZC-2 Cement Accelerator:
It is gray powder, dissolved in water partially, non-toxic and no caustic to person, non-chloride and no rusty damage to steel, and good adaptability to all types of cement.
Specification of ZC-2 Cement Accelerator:
| Solidifying time | at 20±3, the initial and final solidification are 1~3 min and 3~6 min when the adding quantity is 3~4% of cement weight and the water-cement ratio is 0.4 |
| Compressive strength | when the adding quantity is 3~4% of cement weight, 1d compressive strength of concrete is not less than 8Mpa and 28d compressive strength is not less than 90% of that of mortar without Model ZC-2 cement accelerator |
| Fineness | oversize≤12% (by 0.08mm standard screen) |
| Moisture | ≤1.5% |
| Dust concentration | 28.1mg/ m³ (near sprayer) 27.2mg/ m³ (at spraying head) |
| Rebound rate | 15.2% when the adding rate of cement accelerator is 4% |
