Product Description
ART-ZQBHardening accelerating admixture for sprayed concrete
Description
ART-ZQB is a hardening accelerating admixture for sprayed concrete which has the advantages of increase viscosity, good early strength, enhance strength, water retention. It is non-toxic, non-flammable, no corrosion of steel and harmless to human health. It is a high-performance hardening accelerating admixture for use in the wet-mix spraying process. It has good early strength and long-term strength retention rate. It can effectively improve work efficiency and reduce engineering costs, especially suitable for early high-strength shotcrete. Compared with the main hardening accelerating admixture products on the market, it has obvious advantages in technical performance index and cost performance.
Main Characteristics
Good early strength development and continual early-age strength development. Used in conjunction with our alkali free liquid accelerator, 8h strength of sprayed concrete exceeds 12MPa, 1d strength of sprayed concrete exceeds 18MPa, 28d strength ratio is up to 95~110%.
Have a good spraying effect, fast setting hardening, the comprehensive rebound rate of sprayed concrete is ≤10%.
Have slight compensated shrinkage function, preventing cracking after injection molding effectively.
Improve the durability indicators such as impermeability, frost resistance, and freeze-thaw resistance of sprayed concrete.
Little dust and, therefore, a better working environment and improved worker safety.
Green product, non-toxic and harmless in production process, conducive to sustainable development
Applications
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: support in 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 or poor construction, etc.
Protection engineering : all kinds of structure of the fire and corrosion protection, as well as waterproof and plugging engineering.
Fire resistant engineering : the construction and repair of the chimneys and various thermal furnace pits.
