Capram™ Capsules are a cementitious pumped anchoring grout supplied as a ready-to-use dry powder encapsulated in a water permeable skin for easy grouting of rock anchors, particularly of overhead roof bolts as encountered in mining and tunnelling applications.
When required for use, the capsules are soaked in water which is absorbed through the skin to form a thixotropic non-shrink grout.
Additives impart controlled expansion to the grout and reduce water requirement to achieve grout workability. The low water/cement ratio ensures high early strengths, particularly at low temperatures. Cohesiveness of the grout allows it to be used in wet hole conditions.
Advantages
- Non-shrink
- Chloride free and non-toxic
- Thixotropic
- Low water/cement ratio ensures high early strengths
Features
- Encapsulation ensures controlled water/powder ratio and minimal wastage of grout, whilst it eliminates need for mixing equipment
- Thanks to the thixotropic nature of the grout, no loss of grout takes place even from overhead holes
- Rapid strength development without the use of chlorides ensures absence of corrosion
- Expansion agents counteract shrinkage and ensure effective contact between bar and grout
Product Options
- Capram™ Capsules are supplied in woven polypropylene carrying bags with an inner polythene liner (2 capsules per bag) or in water resistant boxes (4 capsules per box).
