摘要
通过材料实验,对大掺量Ⅲa级粉煤灰素混凝土构成的CFG桩桩身材料进行力学性能方面的试验研究,主要探讨抗压强度与材料配比、龄期之间的关系。实验结果表明,大掺量Ⅲa级粉煤灰素混凝土作为桩身材料,在突破传统限制粉煤灰取代水泥率的条件下,仍可达到设计要求的抗压强度。
Laboratory experiment is carried out on the mechanical property of CFG pile material (fly ash concrete) composed of a large quantity of Ⅲa-fly ash mixture. The relationships between compressive strength and the proportion of fly ash substituting cement, and curing time are studied. It is suggested that, while the proportion of fly ash substituting cement is beyond traditional limits, the desired compressive strength still can be achieved.
