采用正交试验方法研究助磨剂对水泥的物理力学性能影响．利用数学软件SAS分析系统，定量地分析粉磨时间、助磨剂掺量、水泥组分含量三因素及其不同水平对水泥细度及强度的影响．结果表明，正交设计的分析结果与试验验证结果有良好的一致性，采用较高的粉煤灰掺量，较低的熟料掺量，适当的粉磨时间和助磨剂掺量可以配制优质P．O42．5R的水泥．

The influence on the grinding aids to the physical mechanics function of the cement was researched by the orthogonal experimental method. The mathematical software SAS was used, the effects of the three factors （ grinding time, the mixing quantity of the grinding aids, cement component content ） and their different levels to the cement fineness and strength were quantitatively analysed. The results showed that the good consistency existed with the orthogonal design and the experimental testing results. The cement of high quality P.O42.5R could be prepared with high fly ash mixed, low clinker content, appropriate grinding time and the mixing quan- tity of the grinding aids.
