摘要
通过试验,研究了轻骨料替代率、水灰比对次轻混凝土抗压、抗折强度的影响。研究表明,随着轻骨料替代率和水灰比的增加,混凝土抗压强度和抗折强度会逐渐降低。轻骨料掺量对抗压强度的影响要高于对抗折强度的影响。
Base on the experiment,the cube compressive strength and rupture strength of the specified density concrete is studied in the paper.The results show that the compressive strength and rupture strength decreases with the increasing of the water-cement ratio and the replacement ratio of lightweight aggregate.The influence of lightweight aggregate replacement ratio on the compressive strength would be greater than on the rupture strength.
