Effect of Curing Time and CaSO₄ Whisker Content on Properties of Gypsum Board

Abstract:

In this thesis, proper amount of whiskers were added to building gypsum used as the basic materials. The gypsum board properties, such as densities and flexural strength etc., were influenced by various whisker content. The results showed that the flexural performance of gypsum board could be enhanced when adding calcium sulfate whisker from a range of 0.5~3 wt.%. The flexural strength reached 5.38 MPa when calcium sulfate whisker content was 1 wt.%. The flexural strength could be higher than that of gypsum board without calcium sulfate whisker by 37.6%.
