摘要

本研究主要探討混凝土含砂率（S/A，細骨材體積/總骨材體積）對流動化混凝土（SCC）彈性模數的影響。研究中以不同含砂率之混凝土配比進行彈性模數試驗，並與一般混凝土比較。混凝土流動性方面則以坍度、坍流度、箱型試驗等進行評估。由試驗結果得知，流動化混凝土的流動性會隨著混凝土含砂率增加而改善。然而對彈性模數而言，當骨材總體積量一定時，改變混凝土含砂率對於彈性模數並沒有太大的影響。

In order to study the effect of sand ratio (S/A ratio, fine aggregate volume/total aggregate volume) on the elastic modulus of self-compacting concrete (SCC), concretes with various S/A ratios were cast and tested. Elastic moduli of SCC were compared with those of normal concrete. Slump flow test, slump test, and box test were carried out to evaluate concrete flowability. The flowability of SCC increases with an increase in S/A ratio. However, the elastic modulus of SCC is not significantly affected by S/A ratio when total aggregate volume is kept constant.
