Construction technology of green concrete
The invention discloses a construction technology of green concrete. The construction technology is characterized in that commercial concrete is delivered to a working surface by a concrete delivery pump and a concrete delivery pipeline; a stone storage silo is mounted above an opening between the tail end of the delivery pipeline of the commercial concrete and an inlet of a helical mixing delivery device; a rotational impeller is arranged at the lower end of a feeding opening of the stone storage silo; extra stones are added from the feeding opening, and are automatically distributed to the flowing commercial concrete by employing the rotation of the impeller driven by the flowing inertia of the flowing commercial concrete; and the extra stones and the flowing commercial concrete are mixed uniformly by the helical mixing delivery device to form the green concrete to be delivered to a spreader pipeline for spreading and pouring. Compared with a construction technology of the conventional commercial concrete, the construction technology of the green concrete has a series of advantages as follows: (1) phenomena of drying shrinkage and cracking are reduced greatly; (2) the green concrete has excellent mechanical property; (3) the volume stability is good; (4) the cement usage is saved to a great extent; and (5) the pumpability of the commercial concrete is not affected.
