The article shows the possibility of using the method of measuring the sound absorption coefficient α to predict the heat resistance and residual life of heat-resistant materials using the example of heat-resistant concrete of three different compositions (without additives, with a plasticizer, with a micro-filler and a combined plasticizer). The critical value of α, corresponding to a significant degree of material destruction, at which further operation is impossible, is established. The primary regression equations, which can be used for approximate prediction of the thermal stability of heat-resistant materials and determination of their residual life, are obtained.

使用声学方法测量吸声系数以预测耐热混凝土的耐久性(耐热性)

文章显示了使用测量吸声系数α的方法来预测耐热材料的耐热性和剩余寿命的可能性,以三种不同成分的耐热混凝土为例(不添加添加剂,不使用增塑剂,微量填充剂和组合的增塑剂)。确定了α的临界值,该临界值与严重的材料破坏程度相对应,无法进一步操作。获得了可用于近似预测耐热材料的热稳定性并确定其剩余寿命的主要回归方程。
