Research on Preparation and Casting Construction Technology of Self-compacting Concrete in Marine Climate Environments

Hou, H., 2020. Research on preparation and casting construction technology of self-compacting concrete in marine climate environments. In: Bai, X. and Zhou, H. (eds.), Advances in Water Resources, Environmental Protection, and Sustainable Development. Journal of Coastal Research, Special Issue No. 115, pp. 1-3. Coconut Creek (Florida), ISSN 0749-0208.In order to meet the requirements of the construction site, self-compacting concrete is mainly to find out how to reduce the water cement ratio to control the occurrence of shrinkage cracks on the premise of meeting the strength and fluidity of concrete, so as to achieve the balance between “high fluidity” and “high stability” of concrete. As self-compacting concrete can improve the construction performance of concrete and reduce labor costs, it is conducive to environmental protection, and at the same time it can improve the mechanical properties and durability of hardened concrete. In order to improve the durability of concrete structure of marine engineering, high performance concrete of marine engineering is used in the wharf and cross Sea Bridge to improve the service life of concrete structure. Based on the analysis of the application significance of self compacting concrete, this paper discusses the design key points of self compacting concrete in the marine climate environment, and analyzes the working and mechanical properties of self compacting concrete in the project.
