通过对16根陶粒混凝土梁和1根普通混凝土梁进行了受弯对比试验,研究了钢筋和陶粒对混凝土梁受弯承载力的影响。结果表明:素陶粒混凝土梁的破坏是由两条贯穿裂缝引起的脆性破坏,其破坏机理是以陶粒破坏为主,破坏断面裂缝贯穿粗集料;混凝土梁的受弯承载力随着陶粒强度和钢筋配筋率的增加呈上升趋势;陶粒的粒径及级配、保护层厚度和钢筋的直径对混凝土梁的承载力也有一定影响。

Ceramsite concrete is seldom applied to load-bearing structures in China. The bending tests were carried out on 16 ceramsite concrete beams and 1 ordinary concrete beam o understand the flexural capacity of ceramsite concrete beams. Influence of ceramsite and steel bar on bearing capacity of ceramsite concrete beams were analysised. The results show that the destruction ceramsite concrete beams without reinforcement is brittle failure caused by two through cracks. Its failure mechanism is mainly the destruction of ceramsite,failure section through coarse aggregate. Flexural bearing capacity of...
