摘要
以挤塑成型制备的制品为对象,研究了以风化页岩部分取代生土材料作为原材料,稻壳灰、水玻璃、植物纤维等改性材料对生土材料制品性能的影响规律,并采用XRD、SEM对改性土进行微观结构分析,探究各种改性材料的改性机理。研究结果表明,植物纤维、稻壳灰、水玻璃等改性材料对制品力学性能和耐久性的改善效果不一致。
Taking the extrusion molding products made of weathering shale and raw soil as research objects, the influence rule of plant ash fiber, rice husk ashand sodium silicate as modifier on extrusion molding product properties are investigated. Besides, the modification mechanism of raw soil wall material is analyzed by using XRD and SEM. The study reveals that the influence of plant ash fiber, rice husk ash, sodium silicate on mechanical properties and water resistance performance is inconsistent.
