摘要：
The addition of ceramsite aimed to improve the toughness of high strength PVA-FRCC and reduce its weight. The quasi-static and dynamic compressive tests were carried out to obtain the compressive strength and the dynamic response of PVA-FRCC with the addition of ceramsite, respectively. The ceramsite can weaken the compressive strength of PVA-FRCC, the quasi-static compressive strength decrease With the increase of ceramsite volume fraction. With the increase of strain rate, the dynamic peak stress and critical compressive strain increase with different ceramsite volume fraction. At the same strain rate level, the dynamic compressive strength decrease with the increase of ceramsite volume fraction. The critical compressive strain of PVA-FRCC with 3% ceramsite volume fraction have the highest critical compressive strain at different strain rate.
