现在设计上给到的空隙率范围为3-5%.

公称最大粒径[ÚnA•¦êmwbbs.3c3t.comÞ<RZ6Àñ¨

(mm)为19,[ÚnA•¦êmwbbs.3c3t.comÞ<RZ6Àñ¨

那么配合比资料中  间隙率最小值应该是多大? [ÚnA•¦êmwbbs.3c3t.comÞ<RZ6Àñ¨
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。[ÚnA•¦êmwbbs.3c3t.comÞ<RZ6Àñ¨
工地上有多种解释,希望得到最权威的解释,非常感谢!![ÚnA•¦êmwbbs.3c3t.comÞ<RZ6Àñ¨
