【Application】
Anchoring anchor bolts of machinery
Grouting in equipment foundation or steel structure pedestal soleplate
Reinforcing, reconstructing and mending building construction
Grouting in pore canal of post-tensioned pre-stressing concrete structure
Anti-seepage anti-cracking waterproof concrete engineering
Grouting in planted reinforcement for embedding
Bridge, road and tunnel engineering
Replacing epoxy resin mortar
【Characteristic】
Early strength and high strength：Compressive strength can reach 50MPa after maintaining for 1 day in good environment. Equipment can be operated and used one day after installation.
Gravitational flow state：Construction can be carried out after watering and mixing on site without vibrating. Mortar flows automatically to prevent open grouting.
Micro expansion：No shrinkage with long-term application of casting body, so as to guarantee the close contact of grouting material and foundation.
Durability：2 million fatigue tests, 50 tests of freezing-melting circulation, without obvious change in strength or later strength decline.
Anti-oil penetration：Strength increases more than 10% before oil immersion after immersing in engine oil for 30 days, applicable to the oil stain environment at the stand.
