S e c t i o n 9 - P a g e 6 May 2013 Uses Cement cartridges wer e developed to anchor mine and tunnel r ock bolts (r ebar and THREADBAR ® ) and to anchor steel dowels in concr ete. Advantages • Convenient easy to handle cartridge form • Fast curing compar ed to or dinary cement gr outs • Contr olled setting times • No on-site mixing, just immerse in water • Thixotr opic and non-shrink • No special gr out pumping equipment r equir ed • High str ength • Non-toxic, non-combustible and chloride fr ee • No r otation Description The system consists of an easy to handle cartridge containing a cementitious compound encased in a perforated package which, when immersed in water , will allow contr olled wetting of contents, forming a thixotr opic gr out. The cartridge is then inserted into the hole and the deformed bolt or dowel is pushed in. Instructions for Use 1. Remove r equir ed number of cartridges fr om package. 2. Immerse cartridges in water until ther e a re no signs of air r elease (bubbling) fr om the cartridge. Do not leave for longer than 5minutes in water . 3. The cement gr out will begin to set in 20 minutes after initial water emersion; ther efor e the bolt must be installed within this time period. However , it is r ecommended that the wetted cartridges be used within 15 minutes to obtain optimum r esults. 4. Insert cartridges into a clean hole. T amp with a loading stick. 5. Insert the bolt. Bolt will ruptur e the cartridges allowing the gr out to fll the annular space between the bolt and the hole. After 12 hours the gr out will typically withstand the full yield point load of the deformed bolts or dowels.
