CF/SSF增强珊瑚砂水泥砂浆的微观结构分析及动态劈裂拉伸试验研究

Microstructure Analysis and Dynamic Splitting Tensile Properties of CF/SSF Reinforced Coral Sand Cement Mortar

摘要: 珊瑚混凝土是一种拉压强度严重不对称的材料，因此对于岛礁防护工程而言，研究珊瑚混凝土的动态拉伸力学性能具有重要意义。为了探究碳纤维（Carbon fiber, CF）和不锈钢纤维（Stainless steel fiber, SSF）增强珊瑚砂水泥砂浆在冲击荷载作用下的动态拉伸力学性能，采用直径100mm的分离式霍普金森压杆（Split Hopkinson Pressure Bar, SHPB）装置进行动态劈裂试验，对比分析不同纤维掺量的珊

Abstract: Coral concrete is a material with severely asymmetric tensile and compressive strengths. Therefore, studying the dynamic tensile mechanical properties of coral concrete is of great significance for island reef protective engineering. To investigate the dynamic tensile mechanical properties of coral sand cement mortar reinforced with carbon fiber(CF) and stainless steel fiber(SSF) under impact loading,
