Hazard 1: If the driver of the transport truck does not rotate the tank during transportation in order to save fuel, he will not be able to rotate the tank due to the serious eccentricity of the tank when unloading at the construction site, resulting in The concrete is scrapped and it takes a lot of time to clear the tank.
Hazard 2: It is easy to cause the pump to be blocked. The segregated material will not be scraped off as long as it is stirred from the bottom of the station to being discharged into the pump hopper. There will be no problem during continuous pumping. When the pump is stopped for one minute, the pipe will be blocked (that is, the slurry will float up, and the sand and gravel will sink close to the pipe wall to form a large resistance, making pumping impossible).
Hazard three: Segregated materials and non-segregated materials in the same mix ratio of concrete will reduce the strength of the concrete by about 10%.
Hazard 4: During the pouring process at the construction site, the floating slurry from the separated concrete mixture will flow out along the formwork joints, polluting the construction environment and causing The demander incurs larger cleanup costs.
