再生橡胶制备自流平隔声砂浆的试验研究

Study on Preparation of Self-leveling Sound Insulation Mortar with Reclaimed Rubber

研究掺入不同比例橡胶颗粒取代石英砂对自流平隔声砂浆流动度、力学性能、收缩性能及动弹性模量的影响,试验表明再生橡胶颗粒可替代部分石英砂制备出性能优良的自流平隔声砂浆,本试验结果显示再生橡胶颗粒掺量15%时,制备的自流平隔声砂浆具有良好的综合性能。

The effects of different proportions of rubber particles instead of quartz sand on the fluidity,mechanical properties,shrinkage and dynamic elastic modulus of self leveling sound insulation mortar were studied.The test shows that recycled rubber particles can replace part of quartz sand to prepare self leveling sound insulation mortar with excellent performance.The test results show that the self leveling sound insulation mortar has good comprehensive performance when the content of recycled rubber particles is 15%.
