The paper presents the laboratory test results of the mechanical properties of porous gypsum. Material for the study was obtained from gypsum Pro-Monta plate of 100mm thick. Based on the compression test of cubic samples, following mechanical properties were determined: compressive strength, Poisson's ratio and Young's modulus. Tensile strength was determined based on three-point bending test of rectangular cross section sample. Also a friction coefficients were investigated as follows: between the smoothed surface of the sample and a fiberboard pad, between a rough surfaces (after cutting) and fiberboard pad. A porosity of the material samples was determined using standard method. The material’s mechanical property values can be useful for modeling destruction and deformation of a porous gypsum undertaken by analytical and numerical methods. |
