HIGH PERFORMANCE CONCRETE WITH HIGH FILLING CAPACITY . ADMIXTURES FOR CONCRETE: IMPROVEMENT OF PROPERTIES. PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM HELD BY RILEM (THE INTERNATIONAL UNION OF TESTING AND RESEARCH LABORATORIES FOR MATERIALS AND STRUCTURES), BARCELONA, MAY 14-17, 1990

This paper describes a mix of High Performance Concrete, which is defined as a concrete with high filling capacity. It can be filled into all the corners of formwork without using any vibrators. The objective of this study is to investigate the role of chemical admixtures such as superplasticizer and viscosity agents on the deformational and segregational behavior of fresh concrete, which is one of the most important studies for developing the concrete with high filling capacity. The optimum mix proportion of superplasticizer and viscosity agent was clarified for the concrete with high filling capacity. It was found that there exists the suitable viscosity of paste for improving not only the deformability but also the segregation resistance, which is highly dependent on the volume of free water in fresh concrete.
