摘要採取長時間浸水馬歇爾試驗和多循環凍融劈裂試驗方法，對摻加了水泥、抗剝落劑的安山巖集料瀝青混凝土水穩定性能進行研究。The research shows that : 1 ) the ductility of the hsc bending members constructed is much greater than 5 ; 2 ) increasing the vertical links and distribution steel can increase the deflection under ultimate moment ; 3 ) with appropriate compressive bars, vertical links and distribution steel the increase of moment after yield and the decrease of moment under ultimate moment can be ignored, so the ductility of the hsc bending member is much larger ; 3 ) the width / depth ratio of hsc bending member has no obvious effect on the ultimate compressive strain of concrete ; 4 ) the method used here to calculate the deflection is applicable ; 5 ) the location of crack coincides with the location of vertical links and distribution steel ; 6 ) the bending property of the hsc structure under the blast load can meet the demand of protective engineering
研究表明：本文研究的梁、板構件的延性比遠大於5 ；增加箍筋（鉤筋、分佈筋）含量，可以提高壓區混凝土剝落時的撓度；在適當的受壓筋、箍筋（鉤筋、分佈筋）含量下，可以忽略壓區混凝土剝落瞬間的承載力下降，從而大大提高構件的延性；受彎構件的寬高比對壓區混凝土極限應變的影響不明顯；受彎構件的裂縫間距受箍筋（鉤筋、分佈筋）的布置影響；文中所用的承載力和變形計算方法是可行的。化爆試驗表明，高強混凝土構件的動載抗彎性能能夠滿足防護結構的要求。Delamination of concrete cover
混凝土保護層層狀剝落The results show that the damages to the appearance of concrete structures exposed to atmosphere, including honeycombing, cracking along rebar, rebar corrosion, and concrete delamination, are quite serious, that the poor quality of concrete construction, the insufficient thickness of local concrete cover, and the rebar corrosion expansion and dilatancy induced by carbonization of concrete cover are the main causes, and that the main form of damages to the overflow structure is the abrasion resulted from water scouring
結果表明，水閘的水上（大氣中）混凝土結構外觀破損十分明顯，露石露砂、順筋裂縫、鋼筋銹蝕、混凝土破損剝落等已十分嚴重；引起破壞的主要原因是混凝土施工質量較差，局部保護層厚度不足，混凝土保護層碳化引起鋼筋銹蝕脹裂，而水流沖刷磨蝕是水閘過流結構破壞的主要形式。The change of specimens scaling mass were measured, both the saturation degree of specimens and its changing rate within freezing - thawing are calculated
並通過測定混凝土試件的剝落量，得出了凍融循環過程中混凝土的飽和系數及變化速率。In chloride environment, chloride penetrates into concrete that will dispassivate the rebar in concrete and induces rebar corrosion. with corrosion developing, the volume expanding of corrosion product lead cover cracking or spalling, a kind of durable failure
在氯離子侵蝕環境下，氯離子侵入混凝土導致鋼筋脫鈍發生銹蝕，隨著銹蝕的發生與加劇，銹蝕產物體積膨脹導致混凝土保護層脹裂或剝落，造成鋼筋混凝土結構發生耐久性破壞。Spalling repair works
混凝土剝落修葺工程Scale resistant concrete
耐剝落混凝土The influence of inorganic salts on mechanical performance of air entrainment concrete is similar with non - air entraining concrete. all those inorganic salts can improve the frost resistance of concrete except calcium nitrite
抗鹽凍剝蝕能力方面，除摻有ca （ no2 ） 2的混凝土表現了較大的剝落量外，其它的混凝土都有較好的抗鹽凍剝蝕能力。It can be concluded from the experimental results that both cement and anti - stripping agent show improvement on moisture stability of asphalt concrete
結果表明，水泥和抗剝落劑均可以提高瀝青混凝土抗水損害能力。The cement concrete pavements in cold regions often suffer from surface scaling or internal cracking under freeze - thaw cycles
寒冷地區的混凝土路面常因凍融循環而表面剝落、內部疏鬆開裂，影響結構的使用。分享友人
