摘　　要：为解决轻骨料混凝土在海洋混凝土平台上的应用问题,分析陶粒种类和矿物掺合料对轻骨料混凝土性能的影响,研究海洋"三高"环境下轻骨料混凝土力学和耐久性能的演化.结果表明,在海洋"三高"环境作用下,大气区的轻骨料混凝土强度和耐久性均高于同龄期潮汐区的轻骨料混凝土强度和耐久性,潮汐对轻骨料混凝土性能退化的影响更加显著.To solve the engineering application of lightweight aggregate concrete in marine concrete platform,the influence of ceramsite type and mineral admixtures on the performance of lightweight aggregate concrete was analyzed,and the evolution of mechanical property and durability of lightweight aggregate concrete in marine"three high"environment was investigated.The results indicated that under the action of marine"three high"environment,the strength and durability of lightweight aggregate concrete in atmospheric zone were higher than that in tidal zone at the same age,tide has a more remarkable effect on the performance deterioration of lightweight aggregate concrete.
