利用早期推定强度控制混凝土质量的方法和效益

METHOD OF EARLY CONCRETE STRENGTH PREDICTION TO CONTROL QUALITY OF CONCRETE AND ITS BENEFITS.

采用早期推定混凝土强度的方法可以缩短配合比试配试验的时间 ,及时发现水泥质量问题 ,充分利用水泥活性 ,使用于生产的混凝土配合比既及时可靠又经济。在施工期间可提早获得混凝土的质量信息 ,发现施工过程的质量问题 ,及时采取相应的措施 ,是采用全面质量管理的行之有效的手段。为提高推定值的准确性 ,还应注意推定公式的修订。

The method of early concrete strength prediction has been adopted,1.to shorten mix-ratio testing period ,2,to reveal instantly cement guality problems,3,to make full use of cement activity,and eventually ,4,to obtain a good concrete mix production of high reliability and fine economy.Moreover,during construction,an early concrete quality information could be duly recieved,and as a result,appropriate measures could be carried out to remedy these quality problems,i.e.,the super-effective method is to have a total quality control.
