中文摘要 | 本文主要針對高強度且高流動之高性能混凝土(High Performance concrete; HPC) 探討漿量、水膠比及泌水對抗壓強度之影響。 混凝土調配先確認滿足設計之工作度及 強度,然後就泌水對其強度之影響予以探討,再針對漿量及水膠比、齡期、尺寸效應等之影 響進行討論。研究結果發現,足夠漿量下試驗室使用之漿量愈小,則強度與理論推導值皆有 愈大之趨勢,而彈性係數值與漿量值有成反比之趨勢,其中 Vp 值愈大時,則其應力-應變 曲線之行為則愈趨平緩。 |
英文摘要 | The influence of paste volume, W/B ratio and bleeding problem to HPC compressive strength was mainly discussed in this paper. Today's HPC intends cantaining high strength, so that its mechanical behavior is similar to high strength concrete. Speaking of the compressive strength, the densified mixture proportion of aggregates, packing effect and hydraulic reaction are also crucial factors except of the application of materials. The bleeding problem was discussed firstly in the paper. Then the paste volume,W/B ratio, age and specimen size effect were studied by following. The result shows that the less the paste volume is applied, the higher the strength will be; the elastic modulus and past volume intends to the negative proportion; while the paste volume is higher, the stress-strain curve behavior intends to be smoother. |
