Transcripción del resumen del autor. Activated mortars were developed by adding polypropylene (PP) fiber and humectants. Physical performance test results show that the compressive strength of the activated mortar is reduced with the addition of PP fibers, and the humectants can markedly reduce the compressive strength of the activated mortars. Resistivity of the activated mortars is also reduced when PP fiber is added, and the added humectants are very useful for reducing the resistivity of the activated mortars.
