    Experimental Study on the Effect of Expansive Agent on the Durability of Concrete in Civil Air Defense Engineering by Junbo Zhang, Jigang Zhang, Weiwei Xiao, Qianying Wang, Feng Shao

    Published 2021-01-01
    “…In this study, the effect of 8% UEA the reason why the UEA content is 8% is as follows: the expansion agent content in the actual mix proportion of the project is 8%, which is selected in this test to fit the reality better. expansion agent on the compressive strength, chloride ion penetration resistance, and carbonation resistance of civil air defense concrete were studied by simulating the rapid carbonation and chloride solution immersion of concrete structure in coastal civil air defense engineering environment. …”
