“…The issues of modeling highly porous thermal protection based on basalt fiber are considered in [7]. The proposed mathematical model of heat transfer in highly porous materials based on fibers provides an explanation of the nature of the stationary mode of the process, takes into account the Stefan-Boltzmann radiation in the pores of a highly porous material, the thickness of the heat shield wall, and the temperature of the hot wall.…”

Based on the analysis and generalization of the results of theoretical and experimental studies, mathematical and computer models of the changes in the physicochemical properties of a heat-shielding material (HSM) made of highly filled elastomers under high-temperature heating and pressure are formulated. The results of the numerical calculations are in satisfactory agreement with the experimental data.

Cement stabilized porous basalt (CSPB) is prone to early agglomeration into lumps owing to the abundant pores and high moisture absorption of porous basalt, making it difficult to unload the mixture at construction sites in high temperatures and rainy areas. To study the construction performance of a CSPB mixture, a novel test method and a convenient device were proposed to test the workability of the cement stabilized macadam mixture, and the evaluation criteria and evaluation method of the workability were proposed based on the tilt angle test. The influencing factors of the workability of CSPB were investigated, and the results show that temperature, delay time, moisture absorption of aggregate, mixture proportion, and construction technology had significant influences on construction performance. Then measures were recommended to improve the construction performance of CSPB. Considering the influence of construction performance on mechanical strength, the effects of temperature, delay time, water reducer dosage, and cement dosage on the mechanical strength of CSPB were also investigated. The results show that temperature and delay time had significant influence on the mechanical strength. The results of this research are of great significance to the field construction of CSPB.
