摘要: 
本研究主要藉由混凝土之耐久性試驗,探討混凝土受海域環境催化下,對其性質影響。現行混凝土耐久性試驗,大多以外在物質(氣體、液體或離子)經混凝土表面「滲入」混凝土內部之行為能力來評估之。本研究利用酸溶法(CNS-1078)硬固混凝土全氯離子含量試驗結果探討氯離子之浸入深度,並配合抗壓試驗、劈裂試驗、孔隙檢測及微硬度試驗,以探討混凝土受海水侵蝕後之行為。試驗變數主要包括海水養護及臨海外環境下兩個部份,並分析添加不同水泥(波特蘭I型及高爐水泥)之混凝土於海水養護及曝露於臨海地區環境下,由混凝土表面至內部各深度之氯離子濃度變化。
研究結果顯示,受海水浸置之混凝土,其抗壓強度有消減現象,可歸因於受海水化性破壞,造成其強度的不利因素,故耐久性較低;另就抗壓強度與劈裂強度之力學性質結果相較,混凝土劈裂強度不受海水中的化性破壞,絕大部份還是受水中養護影響,使海水中養護的劈裂強度大於臨海環境者。混凝土在海水養護比起臨海環境下,其內部總孔隙率還是呈現有較少的結果。而藉由高強度混凝土與添加卜作嵐材料,便能有效抵抗外界離子滲入其內部。並顯示全氯離子濃度偏高其微硬度值呈現有較弱的強度。

The purpose of this project is studied the influence of concrete properties in marine environment by durable experiment. Current test methods for assessing the durability of concrete primarily are based on the ability which the external substances (the gas, liquid or ion) from the surface of concrete “permeate”into the internal part. In this study, the total chloride ions content and penetration depth of concrete will be measured to explore concrete behavior by seawater erosion after rapid chloride ions permeability test(CNS-1078) , other items including compressive strength, splitting strength, MIP porosity measurement and micro-hardness . Experiment variables includes immersion in seawater and exposure in coastal area. Analysis to different cement (Type-I and MS) of concretes affected for immersion in seawater and exposure in coastal area.
Test results show that compressive strength of concrete by immering in seawater is weakened. It ascribed chemical breakage to cause compressive strength is unfavorable effect, and therefore is poor durability. On the other hand, compressive strength and splitting strength are compared on the result of the mechanical properties, and splitting strength of concrete resist the destruction of chemical by immering in seawater. And the greater part is water of influence, so splitting strength in the conservation of water was greater than it in the coastal environment. Within the total porosity of concrete is much less in seawater than in coastal environment. For the test result by high-strength concrete and subjoined Pozzolanic materials, and effective resistance to external ion penetration thus. The total chloride ions were displayed high concentration, and micro-hardness values showed weak strength.
