Abstract
Nowadays, most of the materials used in the construction industry are composites. This is why it is necessary to select their optimal composition, which can be done using the mathematical planning of the experiment. In order to determine the most appropriate composition of the composite material based on gypsum binder with the addition of sawdust according to the criterion of the bending tensile strength, mathematical planning of the experiment was performed. The press was used to measure the bending tensile strength. The regression equation has been also obtained, the response surface has been constructed and the adequacy check of the obtained regression coefficients has been performed.
