コンクリートの時間依存ひずみの予測(都市基盤デザイン工学科)

Abstract

The time-dependent properties of concrete are influenced by many experimental factors such as mix proportion of concrete, material, environmental condition and others. The purpose of this paper is to propose the adequate equations for the prediction of time-dependent strain in concrete. As a result, the followings were obtained. The prediction of the drying shrinkage is put into the percentage of absorption of coarse aggregate. The prediction of the creep factor is divided roughly into the delay elasticity and flow.
