Material de escayola aligerada con polímeros para uso en placas y paneles prefabricados

Abstract

This paper shows the study of a new plaster material for the preparation of prefabricated buildings. As a result of the work, the grant of the patent No. 2 722 598 was achieved, by the addition of polyvinyl acetate, sodium bicarbonate and a boric acid solution to the kneading process of traditional plaster. The type of plaster developed has as its main advantage a decrease of around 30% of its weight. This fact doesn’t decrease its mechanical properties. In addition, tests were carried out reinforcing the plaster with natural and synthetic fibers. Fiberglass was the one that provided the best results. In this way, the preparation of prefabricated panels based on this material would be affected in a positive way. It can reduce both assembly times and the necessary personnel for its execution, thus producing an increase in productivity in the tasks of placing during execution phase.
