Abstract
Printr-un tratament de epurare fizico-chimica a apelor reziduale de la fabricarea pentaeritritei, acestea nu-si pierd total efectul poluant, dar pot fi utilizate ca adaosuri la prepararea betoanelor, mortarelor sau a pastelor de ciment carora le confera calitati îmbunatatite în special prelungirea timpului de priza si cresterea valorilor rezistentelor mecanice. Utilizarea apelor reziduale ca adaosuri în mase pe baza de ciment asigura eliminarea totala a efectului lor poluant.
