Product Introduction
This product is a safe and reliable new type of fast - sealing grouting material. It is an inorganic powder material compounded by specific processes, which consists of silicate - modified materials, mineral admixtures, high - performance admixtures, ultra - fine aggregates (particle size ≤ 0.5mm), etc. During the construction process, no heat is released and no toxic or harmful gases are generated. It is an environment - friendly product.
Performance Characteristics
Simple operation, safe and reliable.
Adjustable setting time, fast solidification speed, which greatly saves construction time.
Slight expansion after solidification, with good sealing effect.
Suitable for sealing holes of gas drainage boreholes.
Scope of Application
Sealing holes of gas drainage boreholes in coal mines.
