(1)减水率:掺MNC—C_1混凝土的减水率为18%～25%,掺MNC—C_2混凝土的减水率为20.7%～24.6%。(2)对混凝土泌水、含气、凝结时间的影响:掺MNC—C混凝土的泌水大大减少,MNC—C_1及MNC—C_2泌水率比分别为0.15、0.10。掺MNC—C_1及MNC—C_2混凝土的含气量分别为2.55、2.8。MNC防冻剂对混凝土凝结时间影响不大。
(1) Water reduction rate: The water-reducing rate of MNC-C_1 concrete is 18%-25%, and the water-reducing rate of MNC-C-2 concrete is 20.7%-24.6%. (2) The influence of bleeding, gas, and coagulation time on concrete: The bleeding of MNC-C concrete was greatly reduced, and the MBC-C_1 and MNC-C-2 bleeding ratios were 0.15 and 0.10, respectively. The air content of concrete mixed with MNC-C_1 and MNC-C_2 was 2.55 and 2.8, respectively. MNC antifreeze has little effect on the setting time of concrete.
