提出对高抛免振捣自密实混凝土的工作机理、配合比设计、工作性评价方法及相应的试验方法。根据上述方法对配置的免振捣自密实钢管混凝土拌合物进行试验验证,并进行了一次与现场施工状况完全相同的模拟高抛试验。试验室数据及现场模拟高抛试验的检测结果证明,提出的研制高抛免振捣自密实混凝土的一整套技术切实可行。 The working mechanism, mix design, workability evaluation method and corresponding test method of high throwing vibration self-compacting concrete are put forward. According to the above method, the configuration of the vibration-free self-compacting concrete filled steel tube is verified by the test, and a simulated high-throwing test is carried out exactly the same with the on-site construction condition. Laboratory data and on-site simulation of the high throw test results show that the proposed development of high throwing vibration self-compacting concrete set of technologies is feasible.
