CGM - 2 high-strength non-shrinkage grouting material of external factors - Zhengzhou grouting material

CGM - High-strength non-shrink grout material CGM - 2 CGM high-strength non-shrinkage grouting material manufacturer - 2 2 high-strength non-shrink grout material price 1, plus the seam an agent CGM - 2 high-strength non-shrink grout material and beautiful seam an agent types much more special, function also each are not identical. Of common beauty water reducing agent, quick-setting seam an agent, early strength seam an agent, etc. Plus the seam an agent has strong CGM - early 2 high-strength non-shrink grout material manufacturers selling become modern CGM - 2 in high-strength non-shrink grout material material not part of the shortage in the civil engineering construction plays a new mix CGM - improvement High-strength non-shrink grout material workability, regulate the new mix CGM - 2 condensation of high-strength non-shrinkage grouting material hardening function, CGM - progress 2 high-strength non-shrink grout material strength and durability or other special functions. But with the seam an agent leads to CGM - 2 increase high-strength non-shrinkage grouting material early to shorten the actual necessary to cause enough attention. 2, aggregate consumption quality and ultra high strength CGM - 2 high-strength non-shrink grout material is the first component of cement stone. Increase aggregate dosage can reduce appropriate reduced. Under the same conditions, choose relatively high elastic modulus of aggregate, can also reduce shorten. 3, environmental conditions, temperature, humidity, wind speed to shorten occur the serious influence. The smaller the higher the temperature, environment humidity, or the wind speed, the greater the CGM - 2 high-strength non-shrink grout material boring speed is faster, in CGM - 2 early high-strength non-shrink grout material condense sclerosis simple cause dry crack, so it is necessary according to the different situation to adopt early sprinkler, moisturizing perhaps steam maintenance measures. 4, water/cement ratio cement CGM - bridge 2 high-strength non-shrink grout material company in the cement dosage is a punctual, water-binder ratio, the greater the mean residual moisture, the more the evaporation of reduced value will also be more accordingly. We will strictly control the water cement ratio, as far as possible by water-binder ratio. 5, dosage of cement and sand and gravel aggregate shorten the value is small, so the CGM - 2 the dry shrinkage of the high-strength non-shrink grout material first shortened from slurry, shorten the value of the slurry can reach more than 2000 x 10. Punctual in water/cement ratio, cement dosage, the greater the CGM - 2 high-strength non-shrink grout material drying shrinkage value. So in the high strength CGM - 2 high-strength non-shrink grout material manufacturing, to control the cement dosage.
