中文摘要 | 本研究中製作不同的細骨材體積比(S/A,細骨材體積/總骨材體積)及 不同水灰比之圓柱試體(Φ100×200mm)進行實驗,以探討骨材彈性模數及 細骨材含量對混凝土彈性模數之影響。文中利用單置入物模式及雙置入物模式 推估混凝土彈性模數。經由試驗數據與理論式節配合,本研究中可求得粗骨材 及細骨材旳彈性模數。研究結果顯示,當總骨材體積為定值時,細骨材體積比 (S/A)對於混凝土彈性模數的影響不顯著。 |
英文摘要 | In order to investigate the elastic modulus of aggregate and the effect of fine aggregate content on the elastic modulus of concrete, cylindrical speciments (Φ100×200 mm) with different volume ratios (S/A , fine aggregate volume/total aggregate volume) and various water/ cement ratios were cast and tested. Both single-inclusion and doubleinclusion models were applied to predict the elastic moduli of twophase and three-phase cement-based composite materials, respectively. The elastic moduli of sand and coarse aggregate were derived from the experimental results using the theoretical models. In addition, the elastic modulus of concrete is not significantly influenced by the S/A ratio for a constant aggregate volume. |
