超高性能水泥基复合材料抗多次侵彻性能研究

Resistance of ultra-high-performance cementitious composites to multiple impact penetration

采用普通混凝土成形工艺和热水养护制度,制备出了抗压强度120～250 MPa的超高性能水泥基复合材料.在获得优异静态力学性能的基础上,进行了超高性能水泥基复合材料抗多次侵彻研究,分析了侵彻过程中的靶体破坏形态.根据获得的侵彻深度数据,在J.T.Gomez等提出的多次侵彻模型基础上,修正了与靶体抗压强度有关的多次侵彻深度计算经验方程.

The ultra-high-performance cementitious composites （UHPCC） with the compressive strength of 120～250 MPa were prepared by using the ordinary concrete molding process and the hot water curing treatment.The behaviors of the UHPCC with excellent static mechanical properties were researched by multiple impact penetration tests.The damage of the UHPCC targets during penetration was analyzed.And based on the multiple penetration model proposed by J.T.Gomez,et al,an empirical formula of penetration depth in relation to the target compressive strength was modified according to the experimental data.
