Construction: reduce winter measures - commonly used high strength without filling and contraction Curtain grouting material manufacturers selling early

High-strength non-shrink grout material early strength grouting since CGM high-strength non-shrinkage grouting material into the early winter in henan province cement, high-strength non-shrinkage grouting material construction in northern temperature fluctuation is very big, this building construction to bring very great battle, in order to ensure the safety of the winter construction, building materials combined with the actual situation of winter construction of zhengzhou sums up 9 am to avoid the shrinkage of high-strength non-shrinkage grouting material construction in winter of the commonly used method. 1, reasonable selection of cement, with low heat of hydration of cement, and high-strength non-shrink grout material unit to minimize the dosage of cement. 2, try to reduce water consumption, adding content mineral admixtures is, reduce the water cement ratio. 3, choose low thermal expansion coefficient, high elastic modulus, gradation and grain shape of prominent aggregate. 4, correct selection and beautiful seam an agent. 5, before mixing equipment secondary high-strength non-shrink grout material cold raw materials. 6, reasonable seam, block, reduce the bound. 7, buried in high-strength non-shrink grout material cooling water pipe. 8, exterior insulation, adjust the appearance temperature drop rate. 9, initial setting before adopting cover maintenance method.
