【摘要】:为进一步改善构件外观质量、提高外压荷载,开展了U型槽混凝土相关性能试验研究。试验设计了不同的干硬性混凝土配合比,通过分析干硬性混凝土拌和物性能与U型槽使用性能的相关性,提出合理控制干硬性混凝土VC值和强度的建议,以满足构件生产工艺及使用性能要求;并结合混凝土配合比参数对干硬性混凝土工作性及强度的影响研究,提出基于拌和物性能控制的配合比设计理念,这样既合理控制干硬性混凝土性能,又保障了构件的质量。
[Abstract]:In order to further improve the appearance quality of the members and increase the external pressure load, the experimental study on the related properties of U-groove concrete was carried out. The different mix ratio of dry hard concrete is designed. By analyzing the correlation between the performance of dry hard concrete and the performance of U type tank, the suggestion of reasonably controlling the VC value and strength of dry hard concrete is put forward. In order to meet the requirements of the production process and the performance of the components, combined with the study of the influence of the concrete mix ratio parameters on the workability and strength of the dry-hard concrete, the design concept of the mix ratio based on the control of the mixing properties is put forward. This not only reasonably controls the performance of dry hard concrete, but also ensures the quality of components.
