Mechanical Gypsum Wall System Performance

Article Preview

Abstract:

This paper has the aim to evaluate the mechanical performance of gypsum walls. It was carried out a laboratory experimental characterization of the gypsum materials properties and different waterproofing contents, which determine their mechanical behaviour, by flexural and compressive strength tests, tensile adhesion and surface hardness. The wall system performance was also evaluated in terms of its water-tightness.The results showed that the samples with lower water repellent additive content present higher compressive strength values and the gypsum walls tested achieved the minimum level of performance (Level M).
