CGM high-strength non-shrinkage grouting material with slump control mixing proportion adjustment scheme

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material manufacturer CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material cooperation than planning, is actually confirmed four basic data ( Cement, water, sand and gravel) Dosage of three links ( The contact of water and cement, water cement ratio show that; Sand and gravel, sand ratio shows; Cement and aggregate, use unit water consumption to echo) 。 In Yellowstone CGM high-strength non-shrinkage grouting material manufacturer line CGM high-strength non-shrinkage grouting material cooperation than planning, first should be in accordance with the requirements of strength grade and durability, to confirm the water cement ratio, then according to the structure or component section basis. Varieties of steel bar intensity, aggregate and particle size range. And the way the operation ( Mechanical vibration or artificial compacted) Factors such as confirm the slump, and hereby confirm unit water consumption through the experiment. Doped with CGM high-strength non-shrinkage grouting material and pressure slurry beauty plus seam an agent of CGM high-strength non-shrinkage grouting material, still should be considered and the influence factors of seam an agent. You can see from this, water cement ratio range is controlled by strength and durability requirements, the slump is restricted to CGM high-strength non-shrinkage grouting material construction operation of liquidity needs. Water-cement ratio and slump planning parameters of two different function, there is no need to contact, although in the case of established cooperation than, luan CGM high-strength non-shrinkage grouting material abnormal shaken, mortar slump will affect the change of the water cement ratio, but not from this we can conclude 'strictly control the water cement ratio' with slump feasible conclusion. When the unit water consumption at the same time, the same CGM high-strength non-shrinkage grouting material liquid mixture ( Slump) Promised to 20 mm, this is a normal phenomenon. , the thickness of aggregate are based on the homogeneous material, slump taken by the determination of mixture could not completely consistent, and it also is a homogeneous mixture material, and is a manual operation, so the slump determination results show some shake, is not surprising. Practice has proved that even the same tank ( Disc) Mixture of the two measurement results are not completely consistent. Previously, slump determination results should take the same tank ( Disc) CGM high-strength non-shrinkage grouting material mixture as experiment confirmed two achievements average value, but both the difference between the measured value shall not be more than 20 mm, otherwise the experimental determination of invalid, sampling from the beginning. Current CGM high-strength non-shrinkage grouting material mixing content function experiment method, does not make clear a regulation, only is pointed out that the scope of determination of slump, the stones larger particle size is greater than 40 mm in CGM high-strength non-shrinkage grouting material, slump is not less than 10 mm CGM high-strength non-shrinkage grouting material mixture, its measurement results in mm, and accurately to 5 mm. In the general CGM high-strength non-shrinkage grouting material cooperation than planning regulation ( JGJ55 - 2000). CGM high-strength non-shrinkage grouting material recommended by water use in the table with the same unit water use corresponding a slump is not fixed, but there are a range of shake the slump values, such as 1 ~ 3 cm, 3 ~ 5 cm and 5 ~ 7 cm, etc. Construction production units entrusted experiment for CGM high-strength non-shrinkage grouting material cooperation than planning to slump value so also puts forward the requirements of the general statements. Therefore, slump within a certain range moved since it is normal, so shake on abnormal sex can't brief 'with slump strictly control the water cement ratio' to deal with. The same slump, is not equal to the same water-cement ratio. Different water cement ratio, can have the same slump. Whereas vision.
