摘要
研究了不同掺量及尺寸油菜秸秆纤维对混凝土表观密度和抗压强度的影响。结果表明,相同配合比条件下,随着掺量的增大,油菜秸秆纤维混凝土表观密度和抗压强度均降低;但当秸秆纤维长度大于2.0cm时,抗压强度降低幅度趋缓,且极限承载状态下表现出良好的塑性。
The influences of different content and size of cole straw on the apparent density and compressive strength of concrete are researched. The results show that under the same mix proportion conditions, with the increase of the amount of cole straw, the apparent density and compressive strength of the cole straw concrete both decrease. However, when the straw length is longer than 2.0cm, the decrease of compressive strength of the concrete has slowed down, and the concrete at the ultimate bearing state shows good plasticity.
