本文介绍了混凝土成分对高强混凝土预制板抗冲击性能影响的实验研究结果。主要测试变量是骨料类型、最大骨料直径、级配曲线和粘结剂含量。测试是使用带有硬核的高速射弹完成的。通过测量弹丸撞击造成的弹坑体积和弹丸的剩余能量来评估面板的抗冲击性。关于骨料，石英岩和玄武岩的使用在生产成本和面板的阻力之间提供了良好的比例。高强度混凝土混合物的粘合剂含量和级配曲线根据每种应用进行调整。最大聚集直径应等于或大于弹丸直径以获得足够的抗冲击性。
This paper presents the results of experimental investigations about the influence of concrete composition on the impact resistance of high-strength concrete prefabricated panels. Main test variables were the type of aggregate, the maximum aggregate diameter, the grading curve, and the binder content. The tests were accomplished using high-speed projectiles with a hard core. The impact resistance of the panels was evaluated by measuring the volumes of the craters caused by the projectile's impact and the remaining energy of the projectile. With regard to the aggregates, the use of quartzite and basalt gives a good ratio between costs of production and the resistance of the panels. The binder content and the grading curve of high-strength concrete mixtures were adjusted to each application. The maximum aggregate diameter were to be equal to or larger than the projectile's diameter to obtain a sufficient impact resistance.
