コンクリート下地セメントモルタル仕上げにおける接着界面に作用するせん断応力度の予測

An approximating method of maximum shear stress on interface between cement mortar and concrete bodies in consideration of composition conditions and outside environment conditions was proposed. Maximum shear stresses were accurately predicted on abbreviated method based on shear lag theory herein. The method was the function of the product of the Young's modulus and differential movements of finishings materials and components. As a result, the degrees for preventing exfoliation in case of actual cement mortar and light mortar renderings in which a moisture and thermal movement occurred, was evaluated.
