西安市建五公司在西安市体育场混凝土框架看台施工中采用了快速脱模施工法.我们利用应力环贯入仪和膨胀压缩仪改装成现用的弹性环测强仪,来测定初浇混凝土强定此仪器在60块用铁模和内壁贴布的木模制做的混凝上立方体试块上和现场混凝士构件上进行了试测。发现采用内壁贴布的木模较铁模为好,混凝土拌合物在振捣过程中,布起过滤作用,从模板缝隙中溢出的基本上是水,带出的水泥极少,使混凝土拌合物变得更加
Xi’an Jianwu Company adopted the quick demoulding construction method in the construction of the concrete frame stand in Xi’an Stadium. We used the stress ring penetrator and the expansion compression instrument to convert the current elastic ring strength instrument to measure the strength of the pre-cast concrete. The instrument was tested on a coagulation cube test block made of wood molds made of iron molds and inner wall patches and on the site of the on-site Coombs member. It was found that wood molds with inner wall patches were better than iron molds. Concrete mixes played a filtering role in the vibrating process. Water overflowed from the template gaps was basically water, and very little cement was brought out to make concrete mixed. Become more
