Purpose. The paper is devoted to cement boards thermal properties based on experimental research and numerical simulation data in relation to nonstationary heat flows.
Methods. Thermal properties were estimated with experimental research and numerical simulation witch both were preliminarily formulated on the base of analogous methods analysis.
Findings. Experimental temperature-time dependencies at both surfaces of flat cement boards samples for different thicknesses in relation to nonstationary heat flows were found. The inverse heat conduction problem was solved and the effective thermal conductivity coefficients were estimated.
Application field of research. The obtained thermal properties can be used in thermal problem evaluating during fire resistance assessment procedures.
Conclusions. (As a result, effective thermal conductivity coefficients for flat cement boards samples were found based on experimental research and numerical simulation data in relation to nonstationary heat flows. Obtained thermal properties give satisfactory convergence used in finite element analysis system simulation compared with the experimental data.
