High strength self-compacting concrete with CGM high-strength non-shrinkage grouting material construction technology of different control - Secondary grouting material

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material manufacturer is 1, the high strength of self-compacting concrete mixing time depending on model performance accurately, long mixing time should not more than three times as many short mixing time; Vibration should be evenly dense, avoid leakage of vibration or vibration. CGM high-strength non-shrinkage grouting material suggests using their compact will not appear this kind of problem. 2, high strength self-compacting concrete mixer, if temperature is exorbitant, aggregate measures should be adopted to cool before stir ingredients. If choose water or ice cooling way, should be timely determination of moisture content, adjust the mixing water, make sure that the water cement ratio not increase. 3, high-strength self-compacting concrete pavement construction before pouring, carefully check the generator or power supply, oscillation beam, equipment and machines like transport vehicles and ensure it in good condition. Should have standby machines on the scene, forbid using the fault machine construction, construction and check whether dredge haul journey, to ensure the continuity of construction. Ingredients, mixing, transportation, paving and other operation should cooperate in order; For climate change, power outages, stop, etc. , should prepare in advance and adjustment process, suspended panel construction. When the shop is installed, from scratch should be dealt with in accordance with the construction joint seams, building materials, CGM high-strength non-shrinkage grouting material construction omit the suddenly stop construction joint treatment, finish earlier period. 4, pay attention to high strength self-compacting concrete face maintenance, especially high strength self-compacting concrete pouring within the first 14 d after ShuRun stick to surfaces. Selects the high quality keep fit the seam an agent or wet method to preserve, unfavorable choose without mulch sprinkler maintenance method. 5, timely and seam, according to the temperature of the construction site and varieties of cement experiment to determine slitting moments earlier, generally should choose more slitting machine operation at the same time, in order to ensure timely kerf width cut to reduce the negative impact of stress effect. Kerf depth of high-strength self-compacting concrete thickness of 1/4 ~ 1/3, unfavorable and seam cut is too shallow, because the rest part section can absorb heat generated by internal stress. Building materials shows that the soft seam cutting process can be slitting early time, prevent cement so high strength self-compacting concrete pavement. 6, control traffic, avoid under the condition of lack of high-strength self-compacting concrete strength, early traffic opening, maintenance vehicles will also should try to avoid directly on the front panel. 7, when choosing vacuum suction process, must pay attention to the overlap between the two suction pad size enough, to avoid leakage. Dowel bar installed correctly, avoid become warped move up and down, can choose double template manipulation. Casting the next high strength self-compacting concrete slab to install according to the design requirements when the plastic casing and bitumen coating layer. 8, the season or region in a larger temperature difference between day and night, high-strength self-compacting concrete road bearing CGM high-strength non-shrinkage grouting material panel guizhou guiyang CGM high-strength non-shrinkage grouting material wholesale surface conditioning process, to set up awnings, prevent sun point-blank, tidy up to cover after the completion of maintenance, to adhere to the road surface temperature difference between day and night change not too big.
