Influence of cement type and type of aggregate on the fresh and hardened properties of UHPC

---

Abstract

Costs for the production of High and Ultra-High-Performance Concrete (HPC and UHPC) can be reduced by using locally available materials. Therefore, this contribution focuses on the influence of cement type on the fresh and hardened concrete properties of self-compacting HPC and UHPC. Eight different types of cement from different cement manufacturers were used in this investigation and were tested for their suitability for the production of HPC and UHPC. In order to determine the cement’s different water demand, an existing UHPC standard recipe, developed at the Institute for Structural Concrete, has been modified for each cement type. The aim was to produce a self-compacting UHPC with each type of cement. The experimental test results demonstrate that compressive strengths > 150 N/mm² are only possible with Portland Cements with low water demand. Furthermore, the influence of cement type and aggregate on the fresh and hardened properties of self-compacting HPC was determined.
