<p>The present invention relates to a cement-based injection grout containing microcement and water for consolidation and/or water proofing fine granular soils, finally fissured soils and cracks in rocks or concrete structures. In addition to microcement and water the grout contains amorphous silica particles in an amount of 5 - 70 % based on the weight of cement and 0 - 10 % water-reducing agents based on the weight of the cement, said grout having a weight ratio between water and cement + amorphous silica between 2 and 8.</p> |
