摘要
实验对采用掺加明矾石类膨胀剂的管棚进行研究,包括膨胀混凝土试件膨胀变形随时间的变化、轴心受压时的应力—应变规律、管棚短柱受压时的应力—应变规律及5 m管棚简支受弯的挠度变化等,同时对普通混凝土管棚的性能进行试验,对试验数据进行对比分析,以得出试验结论。
The experiment researched on pipe roof which is added by alunite type expansive agent,including changes of expansion deformation of the expansive concrete specimens over time,stress-strain law when the axial is compressed;stress-strain law of the short pipe roof columns when compressed and simple flexural deflection change of 5m pipe roof.At the same time,the performance of ordinary concrete pipe roof is tested,the test data is compared and analyzed,and an experimental conclusion is drawn.
