EVALUATION OF CREEP AND SHRINKAGE OF PATENTED MIXTURE OF UHPC WITH APPLIED HEAT-TREATMENT
Original language description
In this paper the description and evaluation of results of experimental verification of rheological properties of patented mixture of ultra-high-performance concrete (UHPC) is presented. Specimens were cured with various curing regimes including curing by an increased temperature and in a water saturated environment. For the evaluation of the results an adapted model B4 is used, which is considered the most advanced rheological material model based on great consistency with large set of experimental results. It seems to be viable for use for prediction of creep and shrinkage of UHPC as it predicts long-term strains by incorporating effect of volume of additives and admixtures used in the fresh concrete. Model B4 also takes into effect thermal treatment of fresh concrete which accelerates cement hydration in early age. Current model B4 has several limitations that are often exceeded by characteristics of UHPC. In this paper, these limitations are identified and viable adaptation of model B4 is presented.
