Beijing high-strength non-shrink grout

High-strength non-shrink grout Features: Zheng 13261978015 or 135215342551, early strength, high strength one day compressive strength ≥ 20Mpa; 3 day compressive strength ≥ 30Mpa; 28-day compressive strength ≥ 55Mpa. 2, close contact between the micro-expansion to ensure that equipment and infrastructure, no shrinkage after the second grouting. 3, high gravity can fill all the gaps and meet the requirements of four secondary grouting equipment, field use anti-segregation overcome segregation because of the increase in the amount of water above normal. 5, resistance to cracking due to the amount of water use in the field of uncertainty, ambient temperature curing conditions of uncertainty and other factors cracking phenomenon. 6, durability million times by 50 freeze-thaw cycle fatigue test experiments no significant changes in intensity. 30 days immersed in the oil intensity has improved significantly. 7, winter construction permits in temperatures of -10 ℃ for outdoor construction. Usage: 1, the basis for secondary grouting equipment. 2, for the anchor bolts and steel plant buried. 3, for the reinforcement and repair of concrete structures. Select a product when the grout layer thickness δ ≥ 150mm, the choice HGM-1 or HGM-2; 2, grout layer thickness 30mm <δ  (GB50204) the relevant provisions. After 3, grout film time to reach demolition, installation can be carried out, the specific time refer to "dismantle film and curing time and ambient temperature of relational tables." 4, after the equipment foundation grouting is completed, if you want to remove part of the grout can be completed in 3-6 hours later, before hardening grout layer gently with a spatula or eradicate shovel tool. 5, may not be rotating machine vibration transmitted to the device based on secondary grouting should be shut down after 24-36 hours, so as not to damage the outstanding hard grout layer. Packing, storage 1, Packing: 50kg / bag.
