摘要
通过对补偿收缩混凝土的作用机理的研究,提出了只掺UEA-S膨胀剂和掺UEAS膨胀剂加MgO膨胀剂的两种试验方案,以便确定最佳掺量以及混凝土配合比。结果表明,只掺UEA-S膨胀剂时,其最优掺量为12%;同时掺UEA-S和MgO,取UEA-S的掺量固定为10%时,MgO的最佳掺量为2.8%~3.3%。
In this paper,through the study of the mechanism of the compensation shrinkage concrete,puts forward the only mixed with UEA- S expansive agent and expansive agent UEA- S two testing scheme of adding MgO style expansive agent,in order to determine the optimal dosage and the mixture ratio of concrete. The results showed that the mixing expansive agent UEA- S,only the optimal dosage is 12%; Mixed UEA- S and MgO style at the same time,apply UEA- s fixed was10%,the dosage of the optimum content of MgO style was 2. 8 ~ 3. 3%.
