INTERNAL ELECTROMAGNETIC FIELD APPLYING APPARATUS FOR ENHANCING LUBRICITY-ACTIVATION OF CONCRETE MATERIALS IN CONCRETE PUMPING AND CONCRETE LUBRICITY-ACTIVATION METHOD USING THE SAME

摘要

The present invention improves lubricity by relieving the surface tension of the concrete to be pushed based on the effect of electromagnetic force, significantly improves the adsorption between cement particles and water molecules, and maintains the material substrate of concrete to settle the structure after curing, The present invention relates to an internal electromagnetic field applying device for enhancing lubrication of internal materials when pumping concrete that can prevent or minimize material separation and sedimentation, and a method for activating concrete lubrication using the same. According to the present invention, the concrete pressing step of pressing the concrete through the pipe in the construction construction; And an electromagnetic field application step of applying an electromagnetic field at a position of at least one location of the pipe through which the concrete is pumped, wherein the electromagnetic field application step is performed by generating an electromagnetic field inside the pipe to be applied to the pressed concrete. A method for activating concrete lubricity of a pressure pipe is provided.
