位于三峡左岸98．7m的混凝土拌和系统，装有日产强制式2×45001IHI楼。为确保混凝土拌和系统质量，曾进行过多项参教试验，在混凝土中既要掺粉煤灰，又要掺复合剂，还要接碎冰。为探索生产这种混凝土拌和物的均匀性与其最佳拌和时间，进行了拌和物在不同拌和时间下的考核、混凝土测温试验、坍落度试验和含气量试验。结果表明，拌和时间延长至110s为最佳拌和时间。 Located in the left bank of the Three Gorges 98.7m concrete mixing system, equipped with Nissan mandatory 2 × 45001IHI floor. In order to ensure the quality of concrete mixing system, have conducted a number of Senate test, both in the concrete mixed with fly ash, but also mixed compound, but also access to ice. In order to explore the uniformity of the concrete mixture produced and the optimum mixing time, the tests of the mixture under different mixing time, the temperature test of concrete, the slump test and the gas content test were carried out. The results showed that the mixing time extended to 110s for the best mixing time.
