摘要

研究了掺加不同粉煤灰量对氯氧镁水泥凝结特性和抗压强度的影响。为此，制备了镁和白云石的两种不同的干混合成分(1:0和1:1)，并在干混合中加入5%、10%、15%和20%的粉煤灰。然后用24°c浓度的氯化镁计量溶液对干混合物进行计量。结果表明，随着粉煤灰掺量的增加，水泥砌块初凝时间和终凝时间均有增加的趋势。粉煤灰掺入比例为1:1的水泥块具有良好的固井性能。

Effect of Admixing Fly Ash on Cementing Characteristics of Magnesium Oxychloride Cement

Investigations pertaining to the effect of admixing different amounts of fly ash on setting characteristics and compressive strength of magnesium oxychloride cement has been carried out in this paper. For this purpose, two different dry mix compositions (1:0 and 1:1) of magnesia and dolomite were prepared and 5 %, 10 %, 15 % and 20 % fly ash were added in dry mixes. The dry mixes were then gauged with 24 °Be concentration of magnesium chloride gauging solution. It was observed that initial and final setting times of cement blocks tend to increase with increasing amount of fly ash in dry mix. MOC cement blocks of 1:1 composition admixed with fly ash displayed good cementing characteristics.
