摘　　要：本文利用"迈地"早强高效减水剂,采用非压蒸养护工艺,在不掺加高活性掺合料情况下,配制C80高强混凝土,在此基础上进行了PHC桩试生产。结果表明,C80高强混凝土管桩非压蒸工艺生产是可行的,其力学性能和产品质量均能达到国标GB13476-92规定的要求。C80 high strength concrete was prepared with 'Mighty' water reducer-early strength high efficency, using non-autoclave curing technologywithout high activated admixture, and trial production of PHC pile was proceeded. The result shows that it is possibility to produce C80 high strength concrete pipe pile using this technOIog. Its mechanical properties and quality of the product all come up to standard GB13476-92.
