The main components of SAⅠadmixture are sulfate, aluminate and organic alcohol amines, etc. It is a high-performance alkali-free shotcrete accelerator for use in the wet-mix spraying process,particularly useful for rapid-hardening concrete and quick-setting concrete. It is non-toxic, non-flammable, no corrosion of steel and harmless to human health.

ART-SAⅠadmixture meet the requirements of Chinese standard JC477 Standard Specification forAdmixtures for Shotcrete and America standard ASTM C1141/C1141M-08.





Low dosage: 5~8% of cementmass, remarkable accelerating performance, short interval between initial and finalsetting time.

Good early strength development and continual early-age strength development. 1d strength of mortar exceeds 10MPa, 28d strength ratio is up to 100~110%.

No alkaline substance, low Cl- content(<0.01%), no bad effect on the durability of concrete.

Have a good injection effect,fast setting hardening, small rebound and less consumption.

Have a slight compensatedshrinkagefunction, preventing cracking after injection molding effectively.



According to the performance indicators and requirements of users, the product is in line with national, industry and enterprise standards.


Underground engineering: mine roadways, traffic tunnels, hydraulic tunnels, underground railways and all kinds of underground tunnels (underground power station, warehouse, etc.) of the supporting lining of the shotcrete;

Rock engineering:supportin wall slopes, excavations, embankments, reservoir engineering, water channels,etc;

Repair and reinforcement works: bridges, seawalls, repair dams, docks, cooling towers, chimneys and the reinforcement of buildings, and the chemical corrosion of oilfields, the building structure repair such as fires, earthquakes, explosion shock overload orpoor construction , etc.

Protection engineering: all kinds of structure of the fire and corrosion protection, as well as waterproof andplugging engineering.

Fire resistant engineering: the construction and repair of the chimneys and various thermal furnace pits.


Guidelines for Use
