防渗透气砂作为一种新型功能材料具有变废为宝的现实意义。本试验用自制防渗透气测试装置测试了防渗透气砂的渗透压、透气速率,在自制防渗透气砂性能量化的同时,通过测试结果分析防渗透气砂的性能影响因素。为防渗透气砂的应用提供参考依据。 Impervious gas sand as a new functional material has the practical significance of turning waste into treasure. In this test, the osmotic pressure and air permeability of the impervious gas sand were tested with a self-made anti-permeate gas tester. While the performance of the self-made anti-permeation gas sand was quantified, the influencing factors of the impervious gas sand were analyzed through the test results. Provide reference for the application of anti-permeation gas sand.
