Concrete floor from sand, cement floor dusting reason, the Department can bridge (certified merchants)

 Cement pavement stones reveal how to do? There cement gravel road how to do? I. Features: BC-type concrete pavement repair material is a cement floor with both adhesive polymer material from the sand treatment agent, and an inorganic material durability of concrete new construction characteristics: 1, to facilitate construction: good Workability 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 workshop concrete floor dusting, 1.7Mpa pressure water impermeability 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 concrete Super high-strength concrete feeding close bond between the grassroots and repair; time is short: 24 hours to traffic after construction; concrete floor crack how to do ground cracks. To Zezheng. Please reasons (Henan Meeting to bridge Detailed) cement concrete crack cracks under the guidance of the great God was mainly due to shrinkage of concrete roadbed subsidence or deformation caused by concrete floor dusting zezheng, specific factors are the following aspects: (1) embankment reason ① Leisure pressure roadbed width narrower than the width of the pavement structure design, so that the edge of the pavement structure fell on the edge of the pavement leading to the emergence soft roadbed longitudinal seam;. ② soft roadbed base tomb not treated or treatment is not complete, so the structure is unstable road, cause pavement cracking: ③ roadbed containing organic matter, organic matter formed after decay empty lip or soft body so stupid road pavement structure supporting force to decrease, resulting in road surface subsidence and cracking: ④ road leather playing compactness reach design requirements After carrying pavement deformation is too large pavement cracks;. ⑤ road bed high, the upper structure of the layer thickness less than the design documentation requirements lead to pavement cracks. Cause sand from the concrete floor from sand, cement floor, the Department can bridge (certified merchants) can be provided by the Department of Road and Bridge Technology Co., Ltd., Henan.
