我们把这些压成细粉，然后混合在水泥及沙里，之后把它放在一个模盒里，作成混凝土制的产品。
We pulverise these to make it powder-like and we mix it with cement and sand and put it in a mould and turn it into concrete products.

试验旨在研究在较高轴压比条件下，高弹模PVA纤维对超高强混凝土短柱抗震延性的改善作用。
The primary objective is to study the effect of high-modulus PVA fibers on improving the seismic performance of super-high-strength concrete short columns with high axial pressure ratio.
