Abstract

Many factors play important role during concreting the base slabs, industrial floors and concrete pavements. Often, there is a tendency to design the structure so that the crack does not arise or arise only with the limited crack width. The parametric study of selected climatic factors which have crucial affect on the temperature or cracking development of the structure at an early stage is elaborated in the paper.The results were obtained using thermodynamic and stress numerical model TD&SM, which was developed in the last four years at the Department of Concrete Structures and Bridges. The outputs from program TD&SM were tested and compared with experimental measurements on real structures, and showed very good agreement. It is possible to calculate the temperature development at any time and place of base slab, industrial floor or concrete pavement at the early stage using this model . It enables afterwards to investigate the risk of crack creation.
