High-strength non-shrink grout material and high strength without shrinkage of self-compacting concrete is a kind of material?

High-strength non-shrinkage grouting material. High strength without shrinkage of self-compacting concrete one, the overview of high-strength non-shrink grout material and what is the difference between high-strength non-shrinkage self-compacting concrete? Say first my company! Our company produces the high strength without shrinkage of self-compacting concrete is a kind of contraction ofnon-vibrating concrete, high strength, is to reduce the project cost and the development of the conventional grouting material replacement. HPC admixture of concrete ( High strength without shrinkage of self-compacting concrete) Performance with the conventional high strength non-shrinkage grouting material, can be self-compacting forming, no shrinkage and hardening process, and the old concrete interface bonding. Second, the performance comparison high-strength non-shrink grout material performance: product model CGM - 380 CGM - 340 CGM - 300 CGM - 270 fluidity ( mm) Initial value or 380 or 340 or 300 or 270 * or 650 * * 30 min retention value 340 or 310 or 260 or greater or more vertical expansion rate (240 * or 550 * * %) 3 h 0。 1 to 3. 5 the expansion of the 24 h and 3 h value difference between 0. 02 ~ 0. 5 product features standard super early strength antifreeze type anti-corrosion type steel fiber heat type ultra strong compressive strength ( MPa) 2 h≥15。 0 1 d≥20。 0 ≥30. 0 ≥10. 0 ≥20. 0 ≥20. 0 ≥30. 0 ≥30. 0 3 d≥40岁。 0 ≥40. 0 ≥15. 0 ≥40. 0 ≥40. 0 ≥50. 0 ≥50. 0 28 d≥60岁。 0 ≥60. 0 ≥60. 0 ≥60. 0 ≥60. 0 ≥80. 0 ≥80. 0 effect on reinforcement rustily no exudation rate ( %) 0 high-strength non-shrinkage self-compacting concrete performance: the performance model of HPC concrete strength value 3 day 30 - 40-50 mpa 28 days 80 mpa water reducing rate of 18 - Old and C30 concrete bonding shear (25% Cut diagonally) The intensity of 9 - 13 mpa, and the old concrete damage level P12 anti-freeze or higher level or higher permeability F150 workability slump - 220 Expansion degree of 500-280 mm, slump 680 mm, their dense forming limit inflation water 7 day 0. 025 - 28 days 0 050% water. 020 - 060% 0 28 days in the air. 010 - 030% exudation rate 0 3, conclusion through the comparison, obviously you can see the difference! The personage inside course of study can simply think of high-strength non-shrinkage self-compacting concrete is ordinary high-strength non-shrink grout material!
