利用粉煤灰和建筑垃圾制备充填材料的研究

Research on preparing backfill material by fly ash and construction waste

主要研究制备固体废弃物制备充填材料的可能性,探究了不同粉煤灰以及建筑垃圾的掺量,不同水泥石灰的掺量对充填材料性能的影响。结果表明:利用固体废弃物制备充填材料可以满足充填材料的性能要求,但随着建筑垃圾掺量的增加,试件28d强度会有所下降;而水泥掺量的增加,能够有效增加充填材料的抗压强度。

This paper studies the possibility of use solid waste to prepare backfill material and explores the effects ofdifferent dosage of construction waste and ash,cement and lime on properties of backfill material.The result showsthat the use of construction waste to prepare backfill material can meet the performance requirements of backfill ma?terial,but with the increase of the amount of construction waste,the28d strength of the specimen will be decreased,while the increase of cement content can effectively increase the strength of the backfill material.
