ST-01S liquid accelerator (without alkali) is low dosage, after using it, Cement concrete set and harden fastly, Initial and final setting intervals short. This product can well suit cements. In the range of 3% -7% dosage of cement quantity, it can meet requirements and indicators of JC477-2005< accelerator for sprayed concrete >. Since this product have no alkali, so it can greatly reduce the damage caused by the introduction of basic substances to concrete, such as alkali silica reaction; at the meanwhile, it strictly limit the content of cl-, so that can reduce the rust to steel. It have no dust and reduce the rebound amount in the during the injection process, so that protect the health of builder and reduce the waste of materials; The hardening concrete has good compactness and good permeability, it also can make up high-strength shotcrete.
