| 摘 要： | 通过将河砂浸泡在氯化钠溶液中来模拟海砂,制成混凝土砂浆,测定其抗折强度、抗压强度和氯离子扩散系数,得出试验结论:经过氯化钠溶液浸泡的砂子制成的砂浆3、28、90d强度略有降低;抗渗性能基本上都有不同程度的提高;对于同一试块,经过一次测量后,养护到一定龄期,再次测量时,氯离子抗渗性能比同一龄期的首次测量要好的多.

| Abstract: | To simulate sea sands,river sands were dipped in NaCl solution,from which grout of concrete were made.Measure the strength of distortion,strength of compression,diffusing parameters of chloride ion and the results could be obtained:grout made from the NaCl solution decrease its strength a little after 3,28 and 90d;impervious behavior,oppositely,would be improved with different degrees;As for any concrete sample,impervious behavior would largely improved after certain age compared with the first measurement. |
