Abstract
The present invention discloses a concrete construction method for controlling setting time and special equipment thereof. The technical solution comprises processes of mixing, pumping, extruding, forming, setting and hardening. An electric treatment of applying an external electric field to a concrete mixture is provided between the pumping and the extruding process. The mixture treated by the external electric field is immediately extruded through an extrusion outlet. The special equipment comprises a transporting pump, a transporting pipeline and an extrusion device. The extrusion device comprises an equipment for electrical process and the extrusion outlet. By adopting the construction solution and equipment in the present technical solution, an effect on rapid controlling or adjusting the concrete setting time is achieved and an early strength of concrete is rapidly and rationally enhanced. A requirement of adjusting concrete setting time at will before the forming process is met.
