CGM - 340 high-strength non-shrink grout material is introduced

CGM - 340 high-strength non-shrink grout material on an article explained the CGM - for both of us 300 high-strength non-shrink grout material, here on CGM - for everyone 340 high-strength non-shrinkage grouting material. It is the county of material particle size is less than 4 specific indicators. Initial fluidity is greater than 75 mm, 340 mm, 30 min retention values greater than 310 mm; 3 h vertical expansion rate at 0. 1 to 3. 5%. The expansion of the 24 h and 3 h value difference of 0. 02 ~ 0. 5%; 1 d compressive strength is greater than 20 mpa, 3 d compressive strength is greater than 40 mpa, 28 d compressive strength is greater than 60 mpa; This material for reinforcement corrosion effect and bleeding rate of 0.
