Non-Explosive Demolition Agent for Rock And Concrete

qiandao new materials Non-Explosive Demolition Agent is a soundless expansive powder developed for controlled rock and concrete splitting through pre-drilled holes. Its calcium-oxide-based formulation hydrates after mixing with water and generates sustained expansion pressure inside the hole. This controlled force guides cracks through natural rock, quarry stone and reinforced concrete without explosive blasting.

The product is supplied in 20 KG moisture-resistant woven bags with inner plastic liners. Four SCA grades are available for ambient temperatures from -5°C to 40°C, helping contractors choose a formulation suited to actual jobsite conditions.
