UHPC performance test device and test method suitable for steel bridge deck pavement
The invention relates to the technical field of ultra-high performance concrete testing, and discloses a UHPC performance testing device suitable for steel bridge deck pavement, the UHPC performance testing device comprises a base, a testing groove and a supporting part, the testing groove is arranged at the top of the base, the first end of the testing groove is hinged to the first end of the base, the testing groove is provided with a pouring cavity, the cavity opening of the pouring cavity faces upwards, the bottom of the supporting part is movably connected with the second end of the base, and the top of the supporting part is movably connected with the second end of the test tank, so that a preset angle is kept between the bottom surface of the test tank and the top surface of the base. Based on the structure, the bridge deck structure with the preset longitudinal and transverse gradients can be simulated, the thickness of the pouring layer from the second end to the first end of the test groove is continuously measured at a certain time interval, namely the thickness of the pouring layer from the high side to the low side, and the fluidity and engineering applicability of the ultra-high performance concrete are evaluated through the thickness deviation of the high side and the low side. Therefore, whether the ultra-high-performance concrete can meet the design requirements or not is judged.
本发明涉及超高性能混凝土试验技术领域，公开了一种适用于钢桥面铺装的UHPC性能试验装置，其包括底座、试验槽以及支撑部，试验槽设于底座的顶部，试验槽的第一端与底座的第一端铰接，试验槽具有浇筑腔，浇筑腔的腔口朝上，支撑部的底部与底座的第二端活动连接，支撑部的顶部与试验槽的第二端活动连接，以使试验槽的底面与底座的顶面之间保持预定角度。基于上述结构，可实现模拟该预定纵横坡度的桥面结构，以一定的时间间隔连续测量试验槽自其第二端至其第一端的浇筑层厚度，即浇筑层自高侧至低侧的厚度，通过高低两侧的厚度偏差评价该超高性能混凝土的流动性和工程适用性，从而判定该超高性混凝土能否保持满足设计要求。
