珊瑚混凝土基础力学性能及工程应用研究现状OA

Coral concrete is a marine engineering material composed of coral sand,reef limestone as aggregates,blended with cementitious materials such as cement,fly ash and admixtures,and mixed with seawater.In marine engineering and island reef construction,it can maximize the use of local materials,save resources and reduce transportation costs,which is of great significance to promote island reef engineering construction.This study systematically introduces the characteristics of coral raw materials,methods for modifying coral concrete,mix proportion design,and research progress in static mechanical performance,dynamic mechanical performance,penetration and explosion resistance.It analyzes the effects of mix proportion design,mineral admixtures and fiber reinforcement technology on improving the mechanical properties of coral concrete.In addition,it discusses and prospects the existing problems in the current research on coral concrete,aiming to provide key technical support for the large-scale application of coral concrete in island reef engineering construction and accelerate the implementation of the maritime power strategy.
