Drying Shrinkage of Cast-In-Situ Concrete in Half-Precast Concrete System Under Restraint Conditions

International Journal of Concrete Structures and Materials
In half-precast concrete (PC) systems, the drying shrinkage of cast-in-place (CIP) concrete is significantly greater than that of PC slabs, which are typically manufactured in factories using well-controlled steam curing. In actual construction, however,

PREDICTION OF OCCURRENCE OF CRACKS DUE TO AUTOGENEOUS SHRINKAGE AND DRYING SHRINKAGE

Doboku Gakkai Ronbunshu, 2000
コンクリートのひび割れ発生時期を予測する研究の一環として, 一軸拘束試験体を用いてコンクリートの収縮によりひび割れを発生させ, 各種の要因がひび割れ発生時期に及ぼす影響, ひび割れ発生点近傍のひずみの挙動, 引張伸び能力や収縮応力強度比のひび割れ発生限界点としての適用性などについて検討し, さらに, 逐次解析を行い実験値と解析値の比較を行った. その結果, コンクリートの収縮ひずみが部材内で均一でないことがひび割れ発生時期をばらつかせる原因であること, ひび割れ発生に影響を与えている範囲から算定した引張伸び能力や, 強度発現条件を考慮した収縮応力強度比は, ひび割れ発生時期を予測する限界点として実用上適用できることなどを示した.

COMPARISON OF DRYING SHRINKAGE AND DRYING CREEP KINETICS IN CONCRETE

Acta Polytechnica CTU Proceedings, 2018
The aim of this paper is to show and compare the time evolution of drying shrinkage and drying creep in concrete from three different perspectives. The first one analyzes the basic equations defined in the most common design codes and prediction models for the description of the long-term behavior of concrete (ACI 209, EC2, Model Code 2010, B3, B4 ...
