Abstract
The purpose of this research is to clarify the influence of construction works on variation in concrete quality, and to establish estimation method of quality variation considering construction conditions (mix-proportions, re-bar conditions, cover concrete depth, etc). In this research, variation in concrete quality obtained by the experiment was quantitatively evaluated using neural network. As a result, the influence of construction conditions on the variation in concrete quality could be clarified quantitatively and the cover concrete quality and its variation could be estimated.
