How To Control Asphalt Concrete Plant Mixed With Concrete
Asphalt mixing plant subdivided into mobile mixing plant water stable, stationary mixing stations and other water-stable category. The mobile station each silo mixing with traction tires can walk, convenient and flexible transitions, lower production capacity. Fixed stabilized soil mixing station, concrete foundations needed, then the device is fixed on it, high production capacity.
Asphalt mixing plant doped concrete admixtures, must be strictly controlled in the content, method and mixed with mixing time, not because mixed with a small number, but neglected, can not save the few mixed with additives as not to shorten the mixing time as accelerate progress.
① To add enough number that every concrete tank must Dosing enough, not when mixed with sometimes mixed, as retarders, in a concrete warehouse, there are retarding concrete, there are no concrete appear slow, due to the uneven solidification time , will make concrete cracks.
② Should be properly mixed with the method, after hydrolysis need not be mixed with the dry mix on the need of caking powder mixed with can not be used, such as aerated water reducing agent or agents, poor control will appear in concrete soft solid group, the formation of pores in the solid concrete.
③ mix asphalt concrete mixing station time must be strictly controlled, 3min should meet requirements such as reducing agent, due to the mixing time is less than its water reduction did not play, in order to meet the requirements of its slump, by adjusting the amount of water to meet slump requirements, the result is to reduce the strength of concrete and concrete will cause segregation and other defects.
