由铁道部科学研究院研究成功的混凝土拌合物稠度试验——跳桌增实法,在铁道部科学技术局主持下于1985年3月1日在北京召开了技术鉴定会。混凝土稠度测试方法,我国通常采用测定经过增实的拌合物在自重作用下的变形的坍落度法,或测定经过增实成形的拌合物重塑至另一形状所需的功的BV法。前者虽然试验简便,但比较粗略,也不适用于干稠拌合物使用;后者虽较适用于较干稠拌合物,但试验振实过程的终者不明显,设备也不易保持在标准状
The Consolidation Test for Concrete Mixtures, which was successfully researched by the Ministry of Railways’ Research Institute of Science and Technology, was conducted in Beijing on March 1, 1985 under the auspices of the Ministry of Railways Science and Technology Bureau. Concrete consistency testing method, China usually adopts the slump method to determine the deformation of the enriched mixture under its own weight, or the BV to determine the work required to reshape the consolidated mixture into another shape. law. Although the former is simple, but it is crude, it is not suitable for use in dry thick mixes; the latter is more suitable for thicker mixes, but the end of the test tapping process is not obvious, and the equipment is not easy to maintain in the standard. shape
