Abstract
The need for rehabilitation of existing structures is currently increasing and will continue to do so in the future. Reinforced concrete facings are considered an effective rehabilitation measure for damaged surfaces of massive concrete structures. The installation of the reinforcement for concrete facings, necessary for crack width control in the structure, is however time-consuming and expensive. The required reinforcement depends mainly on the development of the hydration heat and the resulting restrained deformations at an early age. This contribution presents a numerical model of the concrete facing and the existing structure for the simulation of the stress development due to the hardening of the concrete and the resulting crack formation. The results of the simulation should provide the basis for a future reinforcement optimization. For this purpose, the effect of different cements as well as the influence of the interaction with the existing structure are examined in this contribution.
