摘要


本研究以台灣中部明潭水庫取樣之水庫淤積土,在不同水灰比與齡期進行各項工程力學試驗,量測抗壓強度、延展比、耐磨性與工作度,依其結果進行綜合性之分析探討。而由本研究結果得知,使用淤積土所取代之混凝土於水灰比0.5與1.0時, 28天之抗壓強度分別可達標準混凝土36.2% ~ 73.6% (123.28kg/cm2 ~ 250.27 kg/cm2 水灰比0.5) 與36.6% ~ 77.6% ( 49.57 kg/cm2 ~ 105.22 kg/cm2 水灰比1.0);採用水庫淤積土為細骨材之混凝土於水灰比0.5及1.0之磨損量分別較標準混凝土增加達353.3%與214.3%;工作度分析亦顯示較標準混凝土為佳。本研究結果一般可適用於路寬4M以下產業道路、農路及剛性路面鋪設等等之利用。因此建議適當利用水庫淤積土,能降低工程建造成本及天然骨材耗費的問題,並能減少清淤成本及促進水庫淤積土資源化的利用。

In this study, samples of reservoir sedimentary soils from Ming Lake in central Taiwan were collected and tested, in different water-cement ratio and age for each mechanical test including measuring the compressive strength, ductility ratio, abrasion resistance, slump, and comprehensive analysis of the test results. By the study results, the use of sedimentary soils replacement with water-cement ratio of 0.5 and 1.0 , the 28 days compressive strength were up to that of standard concrete strength at 36.2% ~ 73.6% (123.28kg/cm2 ~ 250.27 kg/cm2 , water-cement ratio of 0.5) and 36.6% ~ 77.6% ( 49.57 kg/cm2 ~ 105.22 kg/cm2 , water-cement ratio of 1.0) ;Using reservoir sedimentary soils as fine aggregate, the concretes have greater amount of abrasion as increased up to 214.3% and 353.3% for w/c ratio of 0.5 and 1.0, respectively. Workability analysis also showed concrete specimens with reservoir sedimentary soil have better results than standard concrete. The results of this study generally usable to the following applications such as 4M lane roads, farm roads and the use of rigid pavement laying, etc. Therefore, the study results recommend that the appropriate use of reservoir sedimentary soils can reduce project construction costs and price of natural aggregate from rivers, and promote reservoir dredging sedimentary soils resource utilization in central Taiwan.
