Abstract　Using orthogonal testing method,the influence of wat er cement ratios,flyash admixed quantities,sand ratios and additive varieties on the concrete strengths， elastic module,dry shrinkage ratios and anti-seepage were studied ,and the primary and secondary influence factors were differentiate d .On the basis of some optimum mix proportions ,the systematic property tests were conducted. The mix proportions of faced concrete and the indexes of physical mechanics parameters for the Shuibuya Project are proposed.
