Features 
 1, as early strength, high strength 
 The compressive strength of ≥ 1 days of 20Mpa or; 3 days compressive strength ≥ 30Mpa; 28 day compressive strength ≥ 55Mpa. 
 2, micro-expansion 
 To ensure close contact between the equipment and infrastructure, secondary grouting contraction. 
 3, the gravity high 
 Can fill all the gaps, to meet the requirements of the equipment secondary grouting. 
 4, the durability 
 No significant changes by 50 freeze-thaw cycle of the millions of fatigue test experimental intensity. 30 days immersed in the oil intensity has improved significantly. 
 5, Winter Construction 
 Construction allows for outdoor temperatures of -10 ℃. 
 Product Use 
 One for equipment foundation secondary grouting. 2, for the anchor bolt anchor and steel plant buried. 
 For the reinforced concrete structure and repair. For beam and column increases the strengthening works. 
 Implementation of the standard GB/T50448-2008
