Zhengzhou concrete floor dusting | Meeting to bridge | cement floor from sand

 Cement pavement stones reveal how to do? There cement gravel road how to do? I. Features: BC-type concrete pavement repair material is a polymer material having both an adhesive, but also has a novel inorganic material durability of concrete construction characteristics: 1, construction is convenient: a good construction and ease of performance. Construction without vibration, mixing with water in the field can be used; 2, early strength, high strength: 2 hours compressive strength of up to 20Mpa, to maximize speed up the progress of the project; 3, strong impermeability: a good impermeability performance, 1.7Mpa pressure water seepage from the sand from the gray cement floor impermeable, in line with P16 impermeability of concrete requirements; 4, good adhesive properties: the bonding strength of new and old concrete is greater than 2.5Mpa, to the maximum extent to ensure high-strength Super high-strength concrete concrete patch repair material and close adhesion between the grassroots; the time is short: 24 hours to traffic after construction; cause of cracks in cement concrete pavement (Henan Meeting to bridge Detailed) cement concrete pavement cracks mainly for surface cracks and through thickness crack (through the cracks), its causes are different. With the development of construction experience, concrete crack repair and now there are many ways: the low-pressure grouting method is applicable to a width of 0.2 ~ 0.3mm concrete crack repair. Repair process as follows: clean up the cracks - cracks paste grouting Tsui and closed - leak - Note the slurry preparation - Pressure Grouting - secondary grouting - clean the surface. When a large number of cracks, first crack at the expected position for a white medical tape affixed stickers, and then narrow brush to seal the seam with a paddle brush back and forth along the crack. Cracks in the concrete floor so closed from the sand, about 10 minutes, thrown off the tape strips, revealing slits, paste grouting Tsui with key package Yan. After curing the periphery may have cracks, it must be repeated with the paste up, in order to avoid leakage of slurry grouting. Grouting operations are generally carried out in the sticky tip of the second day, half a day if the temperature is high, it can grouting. When operating with the first draw to fill joints NOTE slurry grouting nozzle is inserted by hand push piston fill joints, the slurry is pressed into the cracks by grouting nozzle, when the nozzle adjacent slurry flowing out, you can pull up Cement plant seam is ground from the sand, stuffed aluminum rivets. Concrete surface cracks, pores and defects first putty (BC-type repair concrete floor dusting treatment agent) padded flat, polished with emery cloth until dry, then brushing the bottom (BC-type repair concrete floor dusting treatment agent), paint old cement prior to use sand from the ground filtered through iron screens, remove impurities and clumps. The main floor paint to brush three times, each time will have to wait times brushing paint dry and then painted, and preferably two mutually perpendicular directions brushing.
