Unbound and hydraulically bound mixtures - Part 40: Test method for the determination of the direct tensile strength of hydraulically bound mixtures
未结合和水力结合的混合物 - 第40部分:测定水力混合物的直接拉伸强度的试验方法
This standard specifies a method for the determination of the direct tensile strength of test specimens of hydraulically-bound mixtures. The standard applies to medium or coarse grained material specimens made from either laboratory or production mixes. It does not apply to fine grained materials.
