METHODS FOR EVALUATING AND CALCULATING COMPACTION CHARACTERISTICS OF REINFORCED CONCRETE, CALCULATION DEVICE, AND METHOD FOR DESIGNING REINFORCED CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide means that can further quantify compaction characteristics of reinforced concrete.;SOLUTION: The compaction characteristics of reinforced concrete is evaluated by the value of a workability index including the diameter and interval of the reinforcing bars of reinforced concrete. According to the present invention, it is possible to rationally select the manner of bar arrangement, concrete compounding, a vibrating machine, the time of vibration of the vibrating machine, and an interval of insertion, with the workability taken into consideration, in a step of designing the reinforced concrete.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2017,JPO&INPIT
