摘要
通过对钛石膏 -粉煤灰复合路基回填材料的物理力学性能、胀缩性及路用工程性能的试验研究 ,探索了钛石膏 -粉煤灰回填材料的工程性质和性能。试验结果表明 :钛石膏 -粉煤灰复合路基回填材料不仅具有较高的力学性能 (≥ 8MPa)、较好的耐水性和体积稳定性 (膨胀系数≤ 0 .0 2 % ) ,而且具有较佳的路用工程性能。该材料可广泛应用于道路的污水管、输热管、上水管等沟槽的回填。
This paper studied the mechanical properties, expansion and contraction and road performance of backfill material made by waste gypsum from TiO 2 production and fly ash. The results show that the backfill materials not only have high strength (≥8 MPa), better water resistance and volume stability (expansion coefficient≤0.02%), but also have better road performance. This material can be used as backfill around municipal water, sewer and storm drainage pipelines.
