Influence of Water to Cement Ratio with Different Amount of Binder on Properties of Ultra-High Performance Concrete
Keywords:compressive strength, dynamic viscosity, slump, UHPC, W/C ratio
Four different composition 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/m3, 962 kg/m3 and 36.76 l respectively). As binder glass powder and silica fume were used. Optimal fines of glass powder were selected by Chapelle test. In experiment different combinations of silica fume, glass powder and quartz powder as microfiller were used. Compressive strength up to 160 MPa were obtained. The main aim of experiment was to create relationships between w/c ratio and compressive strength and to find optimal composition of UHPC. Slump, dynamic viscosity, density, and compressive strength test methods were used. In experiment glass powder were successfully utilized in UHPC and were obtained essential results for proper composition calculation.
