采用试验室球磨机、工业化TRMK5021水泥立磨等设备,以现场熟料和石膏为原料,从水泥粉磨方式、熟料中C_3S含量、水泥比表面积、是否使用助磨剂等4个方面分析了其对水泥2d抗压强度的影响。结果表明,水泥粉磨方式不是影响水泥2d抗压强度的主要因素;随着熟料中C_3S含量的增加,水泥2d抗压强度增大:每增加1%C_3S,2d抗压强度增加0.3~0.5MPa;水泥比表面积每增加10m2/kg,水泥2d抗压强度增加0.4~0.5MPa;助磨剂对于提高水泥早期强度具有一定作用。通过现场技术沟通与交流,分析了Hume cement公司试验室球磨机制备水泥2d抗压强度高于工业化立磨的原因,并帮助企业解决了早期强度偏低的问题。
Using laboratory ball mill, industrial TRMK5021 cement vertical mill and other equipment to clinker and gypsum as raw materials, from the cement grinding method, clinker C_3S content, cement specific surface area, whether the use of grinding aids and other aspects of its analysis Impact on compressive strength of cement 2d. The results show that the cement grinding method is not the main factor affecting the compressive strength of cement at 2 days. With the increase of C 3 S content in clinker, the compressive strength of cement at 2 days increases: the compressive strength increases by 0.3 ~ 0.5 at 2 days for every 1% C 3 S increase MPa; compressive strength of cement increases by 0.4 ~ 0.5MPa for every 10m2 / kg increase of specific surface area of cement; grinding aids have some effect on improving early strength of cement. Through the field communication and exchange of technology, the paper analyzed the reason why the compressive strength of cement produced by Hume cement Laboratory 2d was higher than that of industrial vertical mill, and helped enterprises solve the problem of low early strength.
