Concrete for non-autoclaved PHC tubular pile and production process of non-autoclaved PHC tubular pile
The invention relates to the technical field of concrete technologies, in particular to concrete for an autoclave-free PHC pipe pile and a production technology of the autoclave-free PHC pipe pile, the concrete for the autoclave-free PHC pipe pile achieves complete replacement of natural sand by machine-made sand by adjusting grading of the machine-made sand and aggregate, and the concrete meetingactual production requirements can be produced. The invention further provides a PHC pipe pile production process, the concrete is used for producing the pipe pile, the prepared pipe pile has good strength and meets the requirements of actual production, meanwhile, the autoclaving step is omitted, the production cost is reduced, and the good economic effect is achieved.
本申请涉及混凝土工艺的技术领域，尤其是涉及一种免蒸压PHC管桩用混凝土及免蒸压PHC管桩生产工艺，其中一种免蒸压PHC管桩用混凝土，通过调节机制砂和骨料的级配，实现机制砂对天然砂的完全替代，可以生产得到复合实际生产需求的混凝土。本申请还提供了一种PHC管桩生产工艺，运用上述混凝土对管桩进行了生产，制得的管桩具有较好的强度，符合实际生产的要求，同时也节约了蒸压的步骤，降低了生产成本，具有较好的经济效应。
