QUALITY CONTROL METHOD FOR FRESH CONCRETE AND METHOD FOR MANUFACTURING CONCRETE STRUCTURE
Document Type and Number:
Japanese Patent JP2016205940
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a novel quality control method for fresh concrete.SOLUTION: The quality control method for fresh concrete includes: filling a mold 100 made of heat-resistant resin with fresh concrete FC; applying pressure to the inside of the mold 100 to dehydrate the fresh concrete FC; irradiating the outside of the mold 100 with microwave M using microwave irradiation means, that is, a microwave oven 200, and curing the concrete in a high temperature and high pressure state with such a temperature setting that temperature inside the mold 100 becomes predetermined temperature or lower at which deformation of the mold 100 can be suppressed in order to harden the fresh concrete FC; removing the hardened fresh concrete FC from the mold 100 to treat it as an accelerated curing test piece TP; and measuring compressive strength of the accelerated curing test piece TP.SELECTED DRAWING: Figure 7
