In order to make the crane stone Choi Ping achieve the best results, it should strictly follow with the main points: 1, the ratio of the concrete structure is not less than C25. 2, shall not be mixed with concrete admixtures containing chloride and calcium oxide or calcium oxide product. 3. The maximum aggregate particles should not exceed 10 mm. 4, concrete air content control at around 6%. 5, in order to improve the crack resistance of concrete, fatigue resistance and impact resistance, it is recommended adding the appropriate steel fibers, glass fibers and polypropylene fibers. 6, the surface layer of concrete paving length class should be coordinated with reasonable construction schedule Crane Choi Ping of stone. In general, the first day should be controlled at 150 m2 / shift, from the next day may be increased to 200 m2 / shift. Especially with the rainy season, the construction length should be controlled in the winter. 7, correctly grasp the frequency, amplitude level in order to avoid artificial concrete from rare phenomenon occurs. 8, strictly control the flatness, cross slope and width, and so on. 9, after laying concrete water should be prohibited. 10, longitudinal seam, shrinking and cutting construction joints and expansion joints should be completed within 24 hours, seam depth of not less than 1/3 of concrete thickness, kerf width should be between the 5-10mm. 11, if the filling material is generally recommended to use low modulus polyurethane and polysulfide rubber-like ointment caulking caulk. 12, transport, paving, vibration, and other processes do face concrete mixture should be close convergence, shortening the process time interval, reducing heat loss.
