Problems solved by technology
And for such as figure 1 As shown, there are formwork filling layer structures in the four directions of up and down, left and right sides. There are few reports on the workability test and evaluation methods of self-compacting concrete, and there are not many successful experiences. In particular, the existing test and evaluation methods are difficult to evaluate self-compacting concrete. The filling fullness between the upper surface of the dense concrete and the top structural layer, the condition of the air bubble layer, etc., are the key points of the problem, and it is too time-consuming and laborious to use the method of direct on-site testing

The invention discloses a self-compacting concrete filling performance testing device. A transparent rigid die box (3) consists of organic transparent rigid plates which are connected to form a whole through bolts, the upper part at one end of the transparent rigid die box (3) is provided with a pouring port (6), the upper part at the other end of the transparent rigid die box (3) is provided with an exhaust port (5), a hopper bracket (2) supports a baiting hopper, and the lower port end of the baiting hopper is provided with a movable valve (7) and is opposite to the pouring port (6). The self-compacting concrete filling performance testing device can quickly and accurately test and evaluate the filling performance of a self-compacting concrete mixture and ensure the construction qualityof a self-compacting concrete filling layer, and has a simple structure and reliable performance.
Description
technical field [0001] The invention relates to a concrete filling performance test device, in particular to a filling performance test device for a self-compacting concrete work performance test method and evaluation technology. Background technique [0002] Self-compacting concrete is a new type of high-tech concrete. Due to its excellent workability, it has attracted the attention of project builders all over the world. It is widely used in the construction of new construction structures that are unfavorable to vibration and compaction such as dense reinforcement and reinforcement repair projects. , to solve the technical problems in the relevant traditional construction. Recently, with the vigorous development of my country's high-speed railway construction technology, self-compacting concrete will also exert its unique performance advantages. Revolutionary high-speed railway slab ballastless track structure technology [1] , whose structure is as figure 1 shown. [00...
