Polyimide strengthened cement mortar
Journal of Polymer EngineeringAbstract This study examined the effects of silane-modified polyimide polymer (PIS) on cement mortar. The PIS was added to replace cement in a specified ratio. Obtained results revealed that the PIS caused retardation on setting time, and accelerated UPV mostly by encapsulating unhydrated cement particles, filling pores, or reacting with

Electrical conductivity of Portland cement mortars
Cement and Concrete Research, 1996Abstract Mortars containing volume fractions of aggregate less than 0.35 were prepared at w c = 0.35, 0.40, and 0.45 and hydrated for 1, 14, and 28 days. Mortar electrical conductivities were determined by impedance spectroscopy, and the experimental data were fitted to the polynomial, where, σm is the mortar σ m = A + B
