Influence of mixing on the fresh and hardened concrete characteristics


Ultra High Performance Concrete (UHPC)

 


Ultra high performance concrete (UHPC) differs from ordinary concrete by its composition and its characteristics. It exhibits a considerably higher powder content with usually a smaller maximum grain diameter, very low water/cement or water/binder ratios and a considerably higher superplasticiser content. UHPC can achieve compressive strengths of over 200 N/mm² and flexural strengths of over 20 N/mm². Due to its dense microstructure it is virtually impermeable to water, chemically aggressive substances and chlorides.
