Effect of thermal treatment of SiC nanowhiskers on rheological, hydration, mechanical and microstructure properties of Portland cement pastes

The properties of silicon nanowhiskers suggest that they are ideal candidates for high-performance cementitious composites. In this study, we used SiC nanowhiskers (SiC NWs) without treatment and treated them at 500 °C. The SiC NWs were dispersed in water, and the corresponding effects of dispersion at 0.25, 0.50, and 1.00 wt% of cement were investigated. The rheological properties and fluidity of cement pastes with the addition of SiC NWs were...
