《锦州增钙粉煤灰在建筑砼楼板中高掺量研究》课题是辽宁省科委1992年下达的科技难题招标项目,由沈阳建筑工程学院、锦州新型建材总公司共同承担完成.有关增钙粉煤灰在建筑砼楼板中高掺量研究的报道国内外很少.经课题组科研人员共同努力,采用高超量系数配比法(超量系数为2)和粉煤灰预处理技术,采用专门适合于高掺量粉煤灰砼的 ZFS—Ⅰ,ZFS—Ⅱ外加剂等技术措施,使 C_(18),C_(28)等级普通硅酸盐水泥砼中粉煤灰掺量可提高到70%,替代水泥35%.
“Jinzhou calcium-advance fly ash in high-volume research in the construction of floor slabs,” the subject is the scientific and technological problems in Liaoning Province Science and Technology Commission issued a tender problem in 1992, by the Shenyang Institute of Construction Engineering, Jinzhou New Building Materials Corporation jointly undertake. About calcium powder There are few domestic and foreign reports on the amount of coal ash in the building floor slabs. With the joint efforts of researchers in the research group, high-to-weight coefficient matching method (exceeding coefficient is 2) and fly ash pretreatment technology have been adopted. Technical measures such as ZFS-I and ZFS-II admixtures for high volume fly ash slag can increase the amount of fly ash in C_(18), C_(28) grade ordinary portland cement slag to 70%. , alternative cement 35%.
