摘要:
选取水泥、废旧混凝土细骨料和海泥为试验材料,通过无侧限抗压强度试验,测定水泥-废旧混凝土细骨料双掺固化海泥(简称双掺固化海泥)的无侧限抗压强度,分析水泥掺量和废旧混凝土细骨料掺量对双掺固化海泥试样无侧限抗压强度的影响,研究双掺固化海泥试样极限应变分布特征。结果表明,本研究中双掺固化海泥试样的无侧限抗压强度随废旧混凝土细骨料掺量的增加而增大,当掺加废旧混凝土细骨料质量与海泥干质量之比为0.12时,无侧限抗压强度提升最明显;试样无侧限抗压强度与水泥掺量呈正相关关系,当掺加水泥质量与海泥干质量之比为0.16时,试样无侧限抗压强度最大。双掺固化海泥极限应变稳定在一个特定区间。

Abstract:
We selected cement, waste concrete fine aggregate and sea mud as experimental materials, and determined the unconfined compressive strength of the sea mud solidified by cement and waste concrete fine aggregate (called double mixing solidified sea mud) using the unconfined compressive strength test. The effects of cement content and waste concrete fine aggregate content on the unconfined compressive strength of the double mixing solidified sea mud specimen were analyzed, and the ultimate strain distribution characteristics of the double mixing solidified sea mud specimen were studied. The results show that the unconfined compressive strength of the double mixing solidified sea mud specimen increases with the increase of the content of waste concrete fine aggregate, and the unconfined compressive strength significantly increases when the ratio of the mass of waste concrete fine aggregate to the dry mass of sea mud is 0.12. The unconfined compressive strength of the double mixing solidified sea mud specimen is positively correlated with the cement content. Specimens have the highest compressive strength when the ratio of the mass of cement to the dry mass of sea mud is 0.16. The ultimate strain of the double mixing solidified sea mud specimen is stable in a certain range.
