Estimation apparatus of the nature of the estimation method and concrete of the properties of the concrete

摘要

PROBLEM TO BE SOLVED: To provide an estimation method for continuously estimating fresh property with sufficient accuracy in normal concrete.;SOLUTION: The estimation method of concrete property includes a property estimation step of inputting fresh concrete C to a hopper 13 of a concrete pump 1, and estimating the fresh property of the fresh concrete C on the basis of an agitation load relating to the rotation of an agitation wing 15 which agitates the fresh concrete C. The property estimation step includes estimating fresh property by comparing the agitation load with the preliminarily specified proper range of the agitation load. In the property estimation step, only the data acquired when the agitation wing 15 is completely buried under the liquid level of the fresh concrete C are adopted as the agitation load to be compared with the proper range.;COPYRIGHT: (C)2013,JPO&INPIT
