Execution standard: technology [2005] No. 101

▲ Product description

  This product is a kind of high performance polymer modified cement based grouting material, which is composed of a variety of organic and inorganic additives. It is of good construction performance, self-leveling, fast early strength development, and it has the characteristics of early strength, high strength, no shrinkage. It can be widely applied to the anchor bolt, machine pedestal, steel structure, foundation rim and large mechanical equipment installation and also suitable for the adjustment of bearing grouting in railway, passenger-dedicated line and highway .

▲ Application method

  Base treatment: before grouting, the filling space has to be cleaned, mainly concerned dust, grease and other scales, etc. In the case of repairing the defects such as cracks, base surface shall be wet by clean water to saturation, but during construction there shall be no visible water.

  Powder dosage and water consumption shall be determined according to the construction area or construction area per unit time. The amount of each batch shall guarantee that all construction is completed before the loss of self-leveling of the mortar.  

  Water to material ratio: water : material = 0.15 : 1

  Mixing: firstly add water to mixing barrel, then discharge the metered grouting material, during feeding while mixing with electric agitator, until the powder is fully discharged out, and continue to stir for 2 to 3 minutes, make the paste even.

  Construction: the mixed ready slurry is poured evenly in treated base surface and keep it self-leveling. Self-leveling shall be completed within the allowable construction time, construction tools shall be washed by water immediately after construction.

  Curing: after the completion of grouting, curing agent shall be immediately sprayed or covered with plastic film, and shielded by the grass sacks or rockwool quilts. The water shall be poured as surface dries, the curing period is 3 to 7 days.
