南海海域全珊瑚海水混凝土抗压强度试验研究

Experimental study on compressive strength of full coral marine concrete in the South China Sea

为研究我国南海海域全珊瑚海水混凝土的抗压强度发展规律,设计了5个系列混凝土进行海水养护,在规定龄期进行立方体抗压强度试验及劈裂抗拉试验。结果表明:全珊瑚海水混凝土抗压强度发展规律与普通混凝土一致,但同强度等级下全珊瑚海水混凝土的早期强度发展明显高于普通混凝土,而后期强度发展较普通混凝土缓慢;相同抗压强度下,全珊瑚海水混凝土的劈裂抗拉强度普遍高于普通混凝土。

In order to study the development of compressive strength of all-coral seawater concrete in the South China Sea,five series of concrete were designed for seawater conservation.Cubic compressive strength test and splitting tensile test were carried out at specified age.The results show that the development law of the compressive strength of the whole coral seawater concrete is the same as that of ordinary concrete.However,the early strength of the whole coral seawater concrete under the same label development is obviously higher than that of ordinary concrete,while the latter strength develops more slowly than ordinary concrete.Under the same compressive strength,all coral seawater concrete splitting tensile strength is generally higher than ordinary concrete.
