Use

• Shotcrete of high quality and with high initial strength for general construction work
• Support at the face of tunneling and securing of rock in tunnel construction
• Rock and slope stabilisation along highways and transportation routes

Characteristics and Advantages

• Chloride-free, suitable for steel reinforced shotcrete and substrates.
• Measurable reduction of rebound.
• Improves bond of shotcrete to rock and concrete, making overhead spraying easier.
• No strength loss of the accelerated concrete if used correctly

Use

Sigunit P1AF is suitable for wet-process shotcreting. The principle applications for Sigunit- P1AF are:

• Support at the face whilst advancing tunnels and mines.
• Rock- and slope stabilisation.
• High quality lining shotcrete.

Characteristics and Advantages

The most outstanding advantages of Sigunit-P1AF shotcrete accelerator are:

• Alkali-free, avoiding additional leaching of alkalis and pollution of ground and surface water.
• When correctly used, marginal reduction of shotcrete strength.
• Reduction of rebound.
• Easier overhead spraying by improved bond of shotcrete to rock and concrete.
• Reduction of dust formation.
• Chloride-free, suitable for steel reinforced shotcrete and substrates.
• Easy to dissolve on site in time for shotcreting.
• Converting powder to liquid on site, the temperature will rise to approx. 40ºC (104ºF); the warm solution will increase the accelerator effect considerably.
• Lower cost of logistics
