Abstract

The chemical hydration involves complex multiphysical processes including mass and energy transfer, chemical reactions and consequently stress development and shrinkage. This paper proposed a multiphysics numerical model to predict the kinetics cement paste. The chemical reaction theory, heat transfer theory, diffusion theory, and continuum mechanics were coupled in the theoretical model. A comprehensive theoretical model is established with partial different equation system, auxiliary functions, and typical boundary conditions.

早期水泥水化的多物理场:理论框架
化学水化过程涉及复杂的多物理过程,包括质量和能量传递、化学反应以及由此产生的应力发展和收缩。本文提出了一个多物理场数值模型来预测水泥浆体的动力学。理论模型中结合了化学反应理论、传热理论、扩散理论和连续介质力学。用偏微分方程组、辅助函数和典型边界条件建立了一个综合的理论模型。
