Abstract
High thickness swelling, high water absorption and low mechanical properties of gypsum particleboard limit its utilization in building construction. Gypsum particleboard reinforced with Portland cement could result in a product with higher mechanical properties and an acceptable resistance to moisture. Physical and mechanical properties of gypsum-cement particleboards were analyzed for specimens previously conditioned at 20 °C and 60% relative humidity and then soaked in water for 24 hours. The results showed that Portland cement incorporation increased the mechanical resistance of the boards. In the dry state, Portland cement addition generated a modulus of rupture increase ratio of 53% and an internal bond strength increase ratio of 206%. Higher increase ratios were obtained after 24 hours water soaking. An increase ratio of 642% was obtained for the modulus of rupture and 97% for hardness. Furthermore, the addition of Portland cement resulted in a reduction ratio of 21% for water absorption after 2 hours water soaking and 26% after 24 hours water soaking. Moreover, reduction ratios of 43% and 61% in thickness swelling and 33% and 46% in linear variation were observed after 2 and 24 hours water soaking. It can be concluded that Portland cement is a suitable reinforcing material for improving the performance of gypsum particleboard.
Zusammenfassung
Große Dickenquellung, hohe Wasseraufnahme und schlechte mechanische Eigenschaften gipsgebundener Spanplatten schränken deren Verwendung im Bauwesen ein. Gipsgebundene Spanplatten verstärkt mit Portlandzement könnten ein Produkt mit höheren mechanischen Eigenschaften und akzeptabler Feuchtebeständigkeit ergeben. Untersucht wurden die physikalischen und mechanischen Eigenschaften von mit Zement verstärkten Gipsspanplatten anhand von Prüfkörpern, die bei 20 °C und 60% rel. Lf. klimatisiert worden waren und anschließend für 24 Stunden in Wasser gelagert wurden. Die Ergebnisse zeigten, dass die mechanischen Eigenschaften der Platten durch Zugabe von Portlandzement verbessert wurden. Durch Zugabe von Portlandzement wurde die Biegefestigkeit im trockenen Zustand um 53% und die Querzugfestigkeit um 206% erhöht. Nach 24-stündiger Wasserlagerung erhöhten sich die Werte prozentual noch stärker. Die Biegefestigkeit nahm um 642% zu und die Härte um 97%. Des Weiteren verringerte sich durch Zugabe von Portlandzement die Wasseraufnahme nach 2-stündiger Wasserlagerung um 21% und nach 24-stündiger Wasserlagerung um 26%. Außerdem wurden nach 2- und 24-stündiger Wasserlagerung eine Abnahme der Dickenquellung um 43% bzw. 61% und der Quellung in Plattenebene um 33 bzw. 46% beobachtet. Daraus kann geschlossen werden, dass die Zugabe von Portlandzement geeignet ist, die Eigenschaften gipsgebundener Spanplatten zu verbessern.
