CGM-T50 STANDARD NON SHRINKAGE GROUTING MATERIAL is formulated in precise test.It adopts cement as binding material, compounds with various admixtures and selected aggregates, supplements additives with high fluidity, micro-expansion, and anti-segregation. The product has advantages of no shrinkage, micro-expansion, Self-flow, vibration-free, non-toxic, harmless, non-aging, no pollution to water quality and surrounding environment, good self-tightness, anti-rust and so on. It fundamentally changes the bearing force of the equipment base so that it can evenly bear the full load of the equipment, thus meeting the installation requirements of various machine, heavy equipment and high-precision machine tools.
