Primary surface treatment a, moisture exclusion concrete moisture content should be less than 5%, or should be ruled out before the water after coating. The method for removing the water are the following: Ventilation: enhance air circulation and accelerate the air flow, remove moisture and promote further evaporation of water in concrete. Heating: improving cement concrete and its long-term production of the ambient air temperature plastic track stadium, accelerate cement concrete water migrate to the surface at a rate of particulate breathable plastic track, it quickly evaporates. It should use forced air heating and radiant heating. b, PH value is greater than the surface back to base 8, with the pickling process: pickling (for more oil in the ground): the mass fraction of 10 to 15% hydrochloric acid to clean concrete surface, until the reaction is complete plastic track, then rinse Stadium plastic runway construction, and scrub with a brush, this method can remove the mud layer and get finer roughness. c, the flatness is poor or too smooth ground surface area without the use of large mechanical methods: blasting or electric grinder to remove surface projections, loose particles, damage pores, increased adhesion area, with a vacuum cleaner sucked sand, impurities, dirt. For more depressions, potholes ground, use plastic and fine particles arranged glue or putty filled patch. Construction steps (1), as required test ground, ground handling and telescopic handle is closed. (2), depending on design requirements and construction programs in the ratio of plastic to use, configure a small amount of plastic, paving trials to determine the handling of the construction program and test foundation. (3) to measure temperature, humidity and other parameters and make a record. (4), drawn construction line construction plans ready for each day. (5), adjust the scale Calibrating equipment, as required Calibrating construction. Construction Tools 1, paver, one Taiwan; 2, grinding machine, one Taiwan; 3, shoot out a machine; 4, material transport vehicles four; 5, a number of other residential construction gadget plastic runway, Jieyang plastic track, Camry sports Ltd. provided by the Dongguan City Camry sports facilities.
