Difference - CGM grout material and concrete construction High pressure grouting plugging grouting material

CGM grout CGM grout material manufacturer CGM grout material price the characteristics of the concrete and the characteristics of CGM grout material has certain differences, construction should pay attention to matters a lot. Cracks in concrete walls usually use CGM grout material to fix, rather than using concrete, that is their different features. Let's look at where they construction difference.     1, before pouring concrete pavement construction, carefully check the generator or power, vibration of beam, equipment and machines like transport vehicles and ensure it in good condition. Site should have standby machines, fault machine construction is strictly prohibited, and check the construction material handling the road was clear, to ensure the continuity of construction. Ingredients, mixing, transportation, paving and other operation should cooperate CGM grout material density; For climate change, power outages, stop, etc. , should get ready for work self-leveling construction minimum thickness of CGM grout material, adjusting process, suspended panel construction. Should press when resurfacing joint construction joint treatment, dalian, remind of the building materials, omit the sudden stop CGM grout material construction material for construction joint treatment, finish earlier period.     2, attaches great importance to the concrete face maintenance, especially within the first 14 d after concrete pouring, to keep the surface ShuRun. By using high-quality health beauty seam an agent or moisture curing, unfavorable use without mulch sprinkler maintenance method.     3, in a larger temperature difference between day and night season or region, the concrete pavement slab surface conditioning process, to set up awnings, prevent sun point-blank, arrange to cover after the completion of maintenance, to keep the road surface temperature difference between day and night change not too big.     4, mixing time according to the model of concrete performance accurately, the longest mixing time should not be more than the shortest 3 times of mixing time; Vibration should be evenly dense, avoid leakage of vibration or vibration. CGM grout material suggest using their compact will not appear this kind of problem.     5, concrete mixing, if temperature is exorbitant, aggregate cooling measures should be taken after mixing ingredients. If using water or ice cooling method, should be timely determination of moisture content, adjust the mixing water, not guarantee the water cement ratio increased.     6, when the suction vacuum technology, it is important to note that overlap between the two suction pad size, enough to avoid leakage. Correct installation of dowel bar, prevent become warped move up and down, can use dual template control. Casting the next to install according to the design requirements when the plastic casing of the concrete slabs and bitumen coating layer.     7, traffic control, avoid under the condition of insufficient strength of concrete, early traffic opening, maintenance vehicles should also try to avoid direct traffic on the panel.     8, timely and seam, according to the temperature of the construction site and cement type test to determine the earliest time, kerf width is generally more slitting machine operation at the same time, should be adopted to ensure the kerf width in a timely manner to reduce the negative impact of cutting stress. Kerf depth of concrete thickness of 1/4 ~ 1/3, unfavorable and seam cut is too shallow, remaining section can absorb in part due to high temperature of CGM grout material density should be no contraction force. Dalian ha o 'donnell building materials shows that soft slitting process can cut seam ahead of time, to prevent cement concrete pavement so.
