摘要
研究了偏高岭土掺量对混凝土抗压强度和工作性能的影响。研究表明:偏高岭土可明显提高凝土的抗压强度,偏高岭土掺量为15%时,混凝土抗压强度较好,28 d抗压强度增长19%,同时随着掺量的增加,混凝土工作性能降低,但可通过适当提高效减水剂的掺量,可保持其工作性能不变。
The influences of metakolin with different mix amount on concrete workability and mechanical properties are studied in this paper, the results show that the compressive strength of concrete can be significantly improved by incorporation of metakaolin, the com- pressive strength can be increased by 19% at 28 d curing age under the optimum mix amount 15%, and the concrete workability does de- cline with the mix amount raising and can be maintained by increasing amount of water reducing agent while.
