F矿粉混凝土是在清华大学土木系研究的基础上,与中国建筑二局合作共同研制开发的。这项成果已于1986年7月通过部级鉴定,并荣获国家科协技术进步发明银质奖。部级鉴定建议F矿粉配置的40MPa以下的混凝土应尽快组织推广。 F矿粉是由天然F岩矿经研磨至与水泥细度相同的粉状物质。F岩矿是一种经天然煅烧后的火山灰质硅铝酸盐矿物质,它含有
The F ore fines concrete was researched and developed in cooperation with the China Construction Second Bureau on the basis of the study of civil engineering at Tsinghua University. This achievement was approved by the ministerial level in July 1986, and won the Silver Award for Technological Progress Invention by the National Association of Science and Technology. The departmental appraisal recommends that concrete below 40 MPa in the F ore fines should be organized and promoted as soon as possible. The F ore fines are ground to a powdery material with the same fineness as the cement by natural F rock mines. F-Rock is a naturally calcined pozzolanic aluminosilicate mineral that contains
