现在设计上给到的空隙率范围为3-5%.

公称最大粒径Ì¿oCI„;¶Nbbs.3c3t.com­5[­îÉ!h

(mm)为19,Ì¿oCI„;¶Nbbs.3c3t.com­5[­îÉ!h

那么配合比资料中  间隙率最小值应该是多大? Ì¿oCI„;¶Nbbs.3c3t.com­5[­îÉ!h
是选3%对应的 12.5%  还是设计 空隙率中值4%对应的13%,如果配合比资料中空隙率为4.1,那么间隙率大于13就行了还是也必须大于13.1。Ì¿oCI„;¶Nbbs.3c3t.com­5[­îÉ!h
工地上有多种解释,希望得到最权威的解释,非常感谢!!Ì¿oCI„;¶Nbbs.3c3t.com­5[­îÉ!h
