Detailed Product Description: | No shrinkage of cement grout strength cement grout secondary grouting equipment German-American foundation grouting equipment, grouting equipment, grouting Model: DMARGrout-618 (the company supporting the supply of electric cement grouting machine screw, cement pump, mortar pump, mortar cement grouting pump manual machine) No shrinkage grouting material is a cement-based cement to the substrate, appropriate amount of high strength with natural aggregate, concrete admixture, composed of dry-mixed material, after mixing with water with high fluidity, early strength, high strength, micro-expansion and other characteristics. Broad-based secondary grouting for equipment, steel column foundation grouting, foundation and other small gap bonding orbital filling, subways, tunnels, underground works against the play embedded solid construction joints, anchor bolts, concrete beams, columns, plates wall reinforcement patch filling, the other ordinary concrete is difficult to cast irregular corners, edges and concrete hollow supplementary irrigation repair. Key Features ◆ High-gravity of the scene just mixing water can be used, no vibration will automatically fill the required gap perfusion: no bleeding, not hierarchical. ◆ early strength of high strength up to 50MPa strength of more than one day, one day after installation to run production. ◆ slight expansion of the high bond strength. With micro-expansion property, no shrinkage, ensuring bolt, equipment and infrastructure as well as between the old and new concrete solid combination. ◆ corrosion resistance early strength grout erosion, erosion resistance, good resistance to sulfate and anti-corrosion properties of water, there is a strong anti-erosion resistance, can be used to harbor, the sewage treatment plant and other projects. ◆ Anti-oil permeability after 30 days immersed in the oil can increase the strength of 10% or more. ◆ durability of the product is inorganic grouting material, no aging, no corrosion of steel. 200 million times of fatigue tests, 50 freeze-thaw cycle test, no significant changes in intensity.
