摘要
The influence of polymer addition on microstructure, performance and mechanical properties of lightweight aggregate concrete was investigated. It was found that the addition of polymer improved the performance and mechanical properties of lightweight aggregate concrete. It was ascertained that the modification of microstructural uniformity and densification with the addition of polymer is responsible for the enhancement of mechanical properties. With respect to compressive strength and bending strength, the lightweight aggregate concrete added with 13% ethylene-acetate ethylene interpolymer (EVA) exhibits preferred mechanical properties. Key words lightweight aggregate concrete - polymer - microstructure - mechanical properties CLC number TU 528.2 Foundation item: Supported by the National Nature Science Foundation of China (50272045)Biography: Jiang Cong-sheng (1963-), male, Ph. D candidate, Associate professor, research direction: advanced architectural materials.
