Concrete Resistance to Cracking due to Shrinkage
This paper suggests an interpretation of the concrete resistance to cracking caused by shrinkage. Cement hydration leads to many chemical processes which cause volume changes and changes of the other physico-mechanical properties of concrete. It is necessary to know the development of residual stresses and corresponding capacity of concrete to establishing of the resistance to shrinkage cracking. Intersection of stress and capacity is a time point which determines that resistance. All necessary concrete properties was established experimentally. The three types of micro-concretes were monitored. On the basis of acquired results it can be stated that the optimal composition of micro-concrete was found because no shrinkage cracks should occur during its life-time.
