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.Through a physicochemical treatment of waste water from pentaerythrite production, they do not completely lose their pollutant effect, but can be used as admixtures for the preparation of concrete, mortars or cement pastes which give them improved qualities, in particular the prolongation socket time and increase of mechanical resistance values. The use of waste water as cement-based admixtures ensures total elimination of their polluting effect.
