Concrete construction technology capable of controlling setting time and special-purpose equipment of concrete construction technology

The invention relates to a concrete construction technology capable of controlling setting time and special-purpose equipment of the concrete construction technology. The construction technology and the special equipment can be provided for 3D (three-dimensional) printing concrete forming and common concrete forming. The construction technology comprises the steps of blending, pumping, extruding, forming and setting and hardening, further comprises a step of performing electric treatment of the applied electric field on concrete mixture between the steps of pumping and extruding and immediately extruding the mixture subjected to electric treatment of the applied electric field after the mixture passes through an extruding opening. The special equipment comprises a delivery pump, a delivery pipeline and an extrusion device, and the extrusion device comprises an electric treatment device and the extrusion opening. By the construction technology and the equipment, the effect of quickly regulating the setting time of concrete is achieved, early strength of concrete is improved quickly and rationally, the requirement of randomly regulating and controlling the setting time of concrete before forming is met, the produced concrete can have good flowability before forming, and the requirements on stirring and delivering are met.
