Abstract

Una composicion de cemento para mortero está compuesta por un cemento o una escoria de cemento portland triturado, piedra caliza y/o cal, arena ysuficiente cantidad de agua para que la composicion sea fluida,y por lo menos un polímero soluble enagua presente en una cantidad que tiene un límite inferiorde aproximadamente 0,001% en peso y un límite superior de aproximadamente 0,04 en peso basado en el peso seco total de los ingredientes, con la condicion deque el grado de absorcion delpolímero s obre el cemento sea inferior a 50% y donde el mortero resultante tenga un contenido de aire de 8-16% y una resistenciade adhesion flexural de 70 psi (483kPa). Esta composicion de cemento para mortero se usa en estructuras paraconstrucciones en todas las zonas sísmicas. Seproporciona también un método para mejorar la resistencia de un cemento para mortero. En donde el polímero soluble en agua se puede seleccionar del grupo queconsiste en: hidroxipropilcelulosa,hidroxietilcelulosa, metilcelulosa , hidroxipropilmetilcelulosa, metilhidroxietilcelulosa e hidroxietilcellulosahidrofobicamente modificada y mezcla de los mismos.
