| Abstract: | Selecting the optimal composition of gypsum concrete with a two-component organic aggregate and glass fiber is a complex task, which in this work was solved using desing of experiment. Adequate mathematical models of tensile strength in bending, compressive strength and water absorption are determined. Based on the mathematical planning of the experiment, the composition of gypsum concrete with the maximum value of tensile strength in bending, which is used in the manufacture of gypsum concrete slabs, was determined. It is shown that gypsum concrete slabs made using casting technology from the developed gypsum concrete composition have a thermal conductivity coefficient K = 0,256 W/(m·K) and provide a noise level reduction to 29,55 dB in the frequency range from 100 to 300 Hz. |
