Abstract

In this paper, adequate modeling of early-age concrete is used to realistically analyze the actual concrete structures at early ages. The models are incorporated into a 3-D finite element procedure. Mathematical formulation of the degree of hydration is based on the combination of 3 rate functions of reaction that represent effects of moisture condition as well as temperature. In moisture transfer, moisture transport coefficient, capacity, and sink are strongly dependent on the degree of hydration as well as the water-cement (w/c) ratio. The realistic models and finite element program developed in this work provide fairly good results on the temperature and moisture distribution for early-age concrete and correlate very well with actual test data.
基于水化程度的早期混凝土结构温湿分布非线性分析
本文通过对早期混凝土进行充分的建模,对实际的早期混凝土结构进行真实的分析。这些模型被整合到三维有限元程序中。水化程度的数学公式是基于三个反应速率函数的组合,这三个反应速率函数表示湿度条件和温度的影响。在水分传递中,水分输运系数、容量和汇量强烈依赖于水化程度以及水灰比(w/c)。本文建立的实际模型和有限元程序对早期混凝土的温度和水分分布提供了较好的结果,并与实际试验数据有很好的相关性。
