Expansive cement

One, HGM grout Products: Case brand strength non-shrink grout with special cement as a binder, selected high-strength materials as aggregate, combined with high flow, micro-expansion, anti-segregation and other substances from the preparation. The product has a gravity is good, fast and hard, early strength, high strength, non-shrink, micro-expansion; non-toxic, harmless, non-aging, water quality and the surrounding environment pollution, since the density is good, rust and other characteristics. With reliable quality, reduce costs and shorten the duration and ease of use in the construction areas. Fundamentally change the base of the forces on the device, so that uniform load to bear all the equipment to meet all kinds of machinery, electrical equipment (heavy equipment, high-precision grinding) installation requirements, is not ideal grout pad installation times. Second, the scope: Case brand strength non-shrink grout material mainly used for: anchor bolts, runway repairs, nuclear power equipment fixed, road and bridge engineering reinforcement, machine base, steel and foundation pregnant mouth, equipment foundation secondary grouting, plant buried reinforced concrete structure reinforcement and renovation of old concrete cracks governance structure, mechanical and electrical equipment installation, rail and installation of steel structures, static piling works pile closures, thickening and leakage of water seepage wall structure repair, grouting collapse of various infrastructure projects and a variety of repair projects. The use of methods 1. Cleaning equipment based on the basis of surface treatment, without gravel, laitance, dirt, grease and mold release agents and other debris. Grouting before 24h, basic equipment should be fully wet the surface. Before filling 1h, should suck water. 2. Filling way to determine the actual situation of equipment base, select the appropriate grout way, because of HGM has good flow properties, under normal circumstances, with "filling weight method" can be, since the template is about to paste directly poured into the mouth completely rely on self-leveling slurry weight and fill the entire space perfusion; if perfusion area of ??the large, complex or spatial structure, especially small and very far away, we can use "high filling funnel method" or "pressure grouting method" grouting to to ensure that the slurry can fully fill every corner. 3. Formwork grout according to the determined way and grouting Figure branch set template, locate the base level should be higher on the device surface at least 50mm, the template must support set tight, secure, prevent loosening, leakage of plasma. 4. Stir grout product certification by the ratio of water to determine the recommended amount of water, mixing water should be used in drinking water, the water temperature to 5 ~ 40 ℃ is appropriate, can be mechanical or manual mixing. When using mechanical stirring, stirring time is generally 1 to 2 minutes. Artificial agitation, advised adding 2/3 of water for 2 minutes, then add the remaining water and continue stirring until evenly, add water standard consistency of 12% -14%.
