Phoscrete SG is a rapid hardening MALP (Magnesium Alumino Liquid Phosphate) concrete for dry process shotcrete / gunite applications.
Phoscrete SG is a two-part cementitious system consisting of a dry mix and a liquid phosphate activator. It is designed for dry process shotcrete and gunite applications, offering rapid setting times, very rapid hardening, and early strength gain. The product is fiber-reinforced and provides high adhesion to concrete surfaces, making it suitable for rehabilitation and new construction projects.
