High-temperature tensile properties of a polymer intercalated/exfoliated cement

A polymer intercalated/exfoliated (PIE) cement is synthesized and its high-temperature tensile performance is characterized. Due to the reinforcing effect of the nanointerphase, the flexure strength of the PIE cement is higher than that of ordinary cements by more than an order of magnitude in a broad temperature range. The temperature at which the optimum mechanical properties are obtained is about 120 °C, and the thermal distortion point is around 180 °C.
