Of the seven use and technical characteristics of grouting material

A, use 1, concrete beam, slab, column, wall body and foundation of renovation and 2, equipment installation and repair of secondary grouting 3 base installation, steel structure column 4, all kinds of machine no shim to install electrical equipment flow 5, anchor bolt anchoring, column base grouting, grouting batholith 6, frame structure joints grouting anchor reinforcement reinforcement, bridge joint 7, grouting, prestressed bridge of post-tensioned prefabricated crack seal 1 second, technology characteristics, early strength, high strength: equipment installation after three days to run the production. 2, their state: the scene only after adding water mixing, direct injection equipment foundation, does not need vibrating can fill all voids of equipment foundation. 3, micro expansion: to ensure that equipment and close contact between foundation. 4, no rust, oil resistance, permeability. 5, durability: 2 million times of fatigue experiment, 50 times of freeze-thaw cycle test intensity has no obvious change. 6, good weatherability 40 ℃ ~ 600 ℃ safe use for a long time.
