摘要(中) 鋼絲網加勁之混凝土(ferrocement)常用以補強鋼筋混凝土抗耐震構件,本文研發新型之鋼絲網加勁水泥複合材料,使用高韌性纖維水泥複合材料取代傳統混凝土材料,以強化構件之拉壓性質、以及破壞模式。研究內容共設計三種不同試體,分別由高韌性纖維水泥複合材料、鋼絲網加勁混凝土、以及鋼絲網加勁高韌性纖維水泥複合材料所製成,採用直接拉力試驗、四點彎矩試驗、剪力試驗以及圍束試驗,探討不同加勁材料所展現之強度、韌性、以及破壞模式,此外,並評估不同鋼絲網加勁材之網格大小與含量對材料行為之影響。實驗結果顯示高韌性纖維水泥複合材料展現良好之裂縫控制效果,於試體表面產生多重細微裂縫;鋼絲網加勁混凝土則擁有良好之消能能力與韌性;而鋼絲網加勁高韌性纖維水泥材料則更進一步改善試體之力學性質,極限拉力強度最高可達8.4 MPa,最大之應變量甚至可高達8%。最後以氯離子穿透性評估材料耐久性,依ASTM C1202推估此新型水泥基材料具中等程度之氯離子滲透抗性。
摘要(英) Ferrocement has often been used to retrofit conventional reinforced concrete members to enhance their seismic performance. This paper develops a new type of steel mesh reinforced cementitious composites. The Engineered Cementitious Composites (ECC) is employed to replace traditional mortar in conventional ferrocement to strengthen the composite’s performance on tension, compression, shear, and flexure. A series of experimental investigations, including the direct tensile test, four point bending test, shear test, and compression test, are conducted to explore the behavior of the newly developed composite. In particular, the impact of the steel mesh size on the new ferrocement’s behavior is assessed. The results show that the steel mesh reinforced ECC possessing an appealing crack control ability, exhibiting multiple tiny cracks on the specimen surface. It is also found that the steel mesh reinforced ECC is able to effectively improve the mechanical properties of the conventional ferrocement. Furthermore, RCPT is carried out to evaluate ECC’s durability. It is found that this new cement-based composite material has a moderate degree of resistance to chloride ion penetration.
