摘要

本文以Ca(OH)2碳化为原型反应模型,研究了非饱和混凝土材料中自愈化学反应与活性流动的耦合关系。多组分流动模型将反应物(Ca(OH)2)和外部触发物(水分和CO2)的浓度与基于线性溶解和沉淀反应动力学的基体局部重塑耦合在一起。该模型再现了碳化反应的主要特征,并预测了由于自愈机制导致的基质孔隙率的降低。

Modelling the carbonation reactions in self-healing concrete
This work focuses on the coupling of the self-healing chemical reactions with the reactive flow in unsaturated concrete materials, using the carbonation of Ca(OH)2 as a prototype reaction model. The multi-component flow model couples the concentration of the reactant (Ca(OH)2) and external triggers (moisture and CO2) with the local remodeling of the matrix based on linear dissolution and precipitation reaction kinetics. The model reproduces the main features of the carbonation reaction and predicts the decrease in matrix porosity due to the self-healing mechanism.
