摘要
本文介绍了磨细矿渣在商品混凝土中的试验和应用情况,采用磨细矿渣、粉煤灰双掺技术可克服混凝土泌水和粘稠性缺点,提高可泵性。同时介绍了掺入激发剂后混凝土早期及后期强度提高的宝贵数据,对广大商品混凝土企业有很大参考价值。
The trials and applications of ground(milled/grinded)slag in ready concrete was introduced in the thesis.Avoiding the shortage of bleeding and viscosity,and improving pumpability can be actualized by using double-mixture with ground slag and fly ash.It supplies the valuable data about strength development after mixing excitation agent into pre-concrete and post-concrete at the same time.All data contents referential values to the most ready concrete companies.
