Large volume, high strength non-shrinkage grouting temperature crack prevention and control of grouting material manufacturer to tell you

High-strength non-shrink grout high-strength non-shrink grout material price high-strength non-shrink grout material manufacturer follow building skills development, high-rise buildings, large volume of CGM high-strength non-shrinkage grouting material the use of the structures is increasing. Large volume of CGM high-strength non-shrinkage grouting material construction quality control is the core content of the gradient of temperature control and crack. Falling mass CGM high-strength non-shrinkage grouting material hydration temperature rise, mainly from two aspects of strengthening skill measures to deal with. 1, carefully graded materials, cement hydration is the main cause of CGM high-strength non-shrinkage grouting material temperature rise, and thus should be preferred to use low heat of hydration of cement, such as slag Portland cement, fly ash, Portland cement, heat or in low thermal cement. Cooperation than planning, should be to ensure that the CGM high-strength non-shrinkage grouting material under the premise of strength, homework and durability, mixed with some mineral admixtures, such as fly ash, ground granulated slag powder, etc. ; Under the condition of may, add aggregate dosage and increase the coarse aggregate size. In addition, the decline in manufacturing especially aggregate data of temperature and mixing the water temperature is big volume, high strength high strength grouting material in wuhan no measures to reduce the temperature rise of the grouting material useful skills. 2, strengthen the construction. Mass CGM high-strength non-shrinkage grouting material craze is not because the environment or CGM high-strength non-shrinkage grouting material inside hardening temperature rise of temperature in the process of resolution, but by the temperature difference of the resolution of CGM high-strength non-shrinkage grouting material list, according to the construction of environmental temperature and CGM high-strength non-shrinkage grouting material may constitute the adiabatic rise of temperature, internal temperature control will CGM high-strength non-shrinkage grouting material list in the lower level is very necessary. Generally thought that, when the CGM high-strength non-shrinkage grouting material list below 25 ℃ temperature difference, can be useful to prevent large volume, high strength without the store that sells CGM grout material through the short grouting material cracks caused by temperature stress. In short, the causes of cracking of CGM high-strength non-shrinkage grouting material, touch the materials, construction, planning and use. CGM high-strength non-shrinkage grouting material engineering measures should be based on specific structure, the specific construction conditions, selecting rational planning, construction plan, and according to the optimization of the cooperation with the corresponding data than CGM high-strength non-shrinkage grouting material. In case is given priority to, combined with prevention and cure.
