This paper presents an experimental investigation on the effect of Nano Silica (NS) on the compressive strength of concrete made with different cement contents. Two percentages of NS, 1.5% and 3%, as partial replacement of cement were investigated at

The present work was accomplished to investigate silica fume (SF) and nano silica (NS) effects on the compressive strength (fcu28) of concrete made by cement contents (CC) of 300, 400, 500 and 600 kg/m3. Two NS types having purity of 89% (Type I) and

Although the temperature stability and uncertainty of the freezing plateau is better than that of the melting plateau in most of the thermometry fixed points, but realization of melting plateaus are easier than that of freezing plateaus for metal fix

Thermocouples are increasingly used in industry and research. For many industrial heating processes, particularly those carried out at high temperatures, a thermocouple is the most convenient and simple instrument for temperature measurement. In some
