  为了模拟研究混凝土海水环境下的侵蚀损伤及劣化规律，采用质量分数10%Na2SO4溶液对混凝土试样进行不同渗透压和不同时长下的室内侵蚀试验。结合微米压痕试验、CT扫描试验和电子显微镜扫描试验，对高渗透压-硫酸盐耦合侵蚀作用下混凝土的侵蚀损伤及微观力学性能进行研究，试验结果显示：（1）渗透压加速了离子迁移，主要起到了促进化学侵蚀作用。（2）渗透压越大，混凝土化学损伤速率越快，侵蚀深度越深。（3）骨料与砂浆胶结处是易侵蚀、易破坏的薄弱点。（4）混凝土内部孔隙易生成水化产物，高渗透压下容易生成大量短柱状石膏晶体及细密的针状钙矾石晶体。", "ds_source": "

 <pre><code> &lt;p&gt;&amp;emsp;&amp;emsp; In order to simulate the corrosion damage and deterioration rule of concrete in seawater environment, indoor corrosion tests were carried out on concrete samples with 10% Na&lt;sub&gt;2&lt;/sub&gt;SO&lt;sub&gt;4&lt;/sub&gt;solution under different osmotic pressures and different time lengths. Combined with the micro indentation test, CT scanning test and electron microscope scanning test, the corrosion damage and micromechanical properties of concrete under the high permeability sulfate coupling corrosion were studied. The test results showed that: (1) The osmotic pressure accelerated the ion migration, mainly played a role in promoting chemical corrosion. (2) The greater the osmotic pressure is, the faster the chemical damage rate of concrete is, and the deeper the erosion depth is. (3) The bond between aggregate and mortar is a weak point that is easy to erode and damage (4) The internal pores of concrete are easy to generate hydration products, and a large number of short column gypsum crystals and fine needle ettringite crystals are easy to be generated under high osmotic pressure.\n
