| titleOfInvention | INJECTION USE AND USE OF THE SAME FOR RENOVATION AND REPAIR OF DRAINAGE PIPES AND PIPES |
| abstract | A new cement mix with low shrinkage is suitable for injection into thin cracks for the repair of sewers and pipes contains less than 5 wt.% of tricalcium aluminate and is milled to 500-700 sqm/kg specific surface using 0.1 to 0.6% sulphonated lignin as milling assistant. It is gypsum free. The binding time and strength are regulated by additions of 0.1 to 1% of sulphonated polyelectrolyte, of 0.2-2% of an alkali metal carbonate. Ballast components comprise 30-35% of cement wt., water addition is 20-25 wt.%. |
