- Abstract
- This investigation pertains to the properties of wall and plaster boards and the suitability of fiber insulating boards as a plaster base. Such properties as density, strength (flexural and tensile), and linear changes accompanying changes in relative humidity and wetting and drying were studies. The boards were mounted on steel frames and the extent of buckling resulting from changes in relative humidity were determined. Methods of successful application of plaster on insulating lath were determined by experiments in which the thickness, sand content, strength, and time of set of the plasters were varied independently.
