英文摘要 | 輕質骨材混凝土之可達強度主要係決定於混凝土中骨材之堆積強度與砂漿強度。 砂漿強度一般可做水灰比值預估之, 但骨材堆積強度至目前為止, 尚無有效的方法求得。 1972 年, Weigler 以理論方式提出輕質混凝土具有分界強度,本文則嘗試以實驗手段證明 分界強度之存在,並驗證以量化之分界強度值可合理的代表無法測知之骨材堆積強度值。最 後,變化混凝土中輕質骨材之含量及粗骨材最大粒徑,瞭解其對分界強度值影響。 e the packing strength of lightweight coarse aggregate. Test results have shown that for lightweight aggregate concrete a dividing strength indeed exists. In addition, the dividing strength can then be reasonably adopted as an indicator in representing the packing strength of lightweight aggregate. Finally, as the maximum size or the volume content of the coarse aggregate varies, the corresponding packing structure and the packing density of the lightweight concrete will be different, leading to a change of the dividing strength. |
