摘要
为研究海藻杂质对珊瑚混凝土性能的影响,在标准养护和海水浸泡养护两种环境下,通过对不同海藻杂质掺量珊瑚混凝土进行力学性能试验,研究了养护时间和养护环境对珊瑚混凝土力学性能的影响。研究发现:海藻杂质对混凝土的抗压强度、劈裂抗拉强度和抗折强度均有不利影响;杂质含量小于0.5%基本不影响珊瑚混凝土的抗压强度;在标准养护和海水浸泡养护两种养护环境下,海藻杂质掺量较低组别的珊瑚混凝土抗压强度变化幅度相对较小,而掺量较大的珊瑚混凝土受影响较大。
In order to study the influence of seaweed impurities on the performance of coral concrete,it conducted mechanical performance tests on coral concrete with different amounts of seaweed impurities under standard curing and seawater immersion,and studied the effect of curing time and curing environment on the mechanical properties of coral concrete.The study found that seaweed impurities have adverse effects on the compressive strength,splitting tensile strength and flexural strength of concrete.Impurity content less than 0.5%basically does not affect the compressive strength of coral concrete.In standard curing and seawater immersion curing under the environment,coral concrete with a lower amount of seaweed impurity has a relatively small change in compressive strength,while coral concrete with a larger amount is more affected.
