本研究主要探討生態水泥特性及其對混凝土力學性質及耐久性之影響。混凝土試體包括四種水灰比(w/c=0.35,0.45, 0.55,0.65)並利用氯離子快速滲透試驗評估生態水泥混凝土氯離子滲透性。水泥砂漿試體以固定水膠比為0.65用不同重量比例(0%,30%,60%)爐石粉取代水泥置入鋼筋進行加速腐蝕試驗,並以電化學法量測腐蝕電位及腐蝕電流。
試驗結果顯示生態水泥與普通卜特蘭水泥略有不同,生態水泥砂漿(混凝土)的力學性質較普通卜特蘭水泥砂漿(混凝土)略差。而混凝土氯離子滲透性,低水灰比(0.35,0.45)生態水泥混凝土試體6小時電流及總通過電量均較普通卜特蘭水泥混凝土試體低,但在高水灰比(0.55,0.65)時,生態水泥混凝土試體6小時電流及總通過電量卻較普通卜特蘭水泥混凝土試體高。水膠比0.65時不論爐石粉取代量多少,鋼筋在生態水泥試體中之腐蝕電位較普通卜特蘭水泥試體低,而腐蝕速率則較普通卜特蘭水泥者高。
Eco-cement, a new type hydraulic cement, is made from the incinerated ashes or municipal wastes. The objective of this study is to investigate the characteristics of eco-cement, compressive strength and durability of eco-cement concrete. Rapid chloride penetration test (RCPT) was performed to evaluate concrete durability of concretes. In addition, open circuit potential method was applied to measure rebar corrosion trend of mortar specimens with a w/b ratio of 0.65 and different slag replacement ratios.
Testing results show that the characteristics of eco-cement are not much different from ordinary Portland cement (OPC). The compressive strength of eco-cement is lower than that of the control but still satisfies the requirements of CNS 61 R-2001. Eco-cement specimens with lower w/c ratios (0.35,0.45) shows lower total-charge passed than OPC specimen, but on the opposite for specimens with higher w/c ratios (0.55,0.65). On the other hand, the open circuit potentials show the higher corrosion probability for eco-cement specimens.
