Four different compositions of ultra-high performance concrete (UHPC) have been created for this study, while W/C ratio varied from 0.25 to 0.33. Amount of cement, quartz sand and super plasticizer has been maintained constant (at 735 kg/m 3 , 962 kg/m 3 and 36.76 l respectively). Glass powder and silica fume were used as binder. Optimal fineness of glass powder was selected by Chapelle test. In this study different combinations of silica fume, glass powder and quartz powder as microfiller were used. Compressive strength up to 160 MPa was obtained. The main aim of experiment was to create relationships between w/c ratio and compressive strength and to find optimal composition of UHPC. Test methods such as: slump, dynamic viscosity, density, and compressive strength were used. In experiment glass powder was successfully utilized in UHPC.
