Ultra High Performance Concrete withultrafine particles other than silica fume

A comparison of different cement extenders

Several ultrafines were used to produce Very High Performance Concrete (VHPC) and Ultra High Performance Concrete (UHPC). The ultrafine powders used were metakaolin (MK), pulverized fly ash (PFA), limestone microfiller (LM), siliceous microfiller (SM) and micronized phonolith (PH). This paper deals with the performances obtained with these ultrafines: compressive and tensile strength, porosity, water absorption and resistance to carbonation. The results show that other ultrafines than silica fume can be used in VHPC and UHPC.
