进行了一系列平板冲击实验，以评估微混凝土（70%细粒粗玄岩粉末和30%水泥浆）在纵向和横向上的动态行为。获得了Hugoniot曲线和动态剪切应力特性的信息。Hugoniot的结果与英国、德国、法国和美国公布的水泥浆、砂浆和混凝土数据进行了比较。当将微混凝土的剪切强度与水泥浆进行比较时，观察到非常小的差异。因此，该体系的剪切强度似乎与骨料无关，而主要取决于基质材料。
A series of plate impact experiments has been performed to assess the dynamic behaviour of micro‐concrete (70% fine‐grain dolerite powder and 30% cement paste by weight) in both longitudinal and lateral directions. Information was obtained for the Hugoniot curve and dynamic shear stress properties. Hugoniot results are compared with published data on cement paste, mortar and concrete from the UK, Germany, France and the US. When the shear strength of micro‐concrete is compared to the cement paste very small differences are observed. Therefore, the shear strength of this system appears to be independent of the aggregates and mainly depends on the matrix material.
