Study on the Increase of the Supporting Capacity of a Cement Milk Pile with Expansive Additives

In this study, an engineering characteristic test was conducted on cement milk using expansive additives during the construction of bored piles. Expansive additive mixtures with various mixing ratios were prepared according to the construction standards of the Korea Expressway Corporation. Segregati...

Expansive additive mixtures with various mixing ratios were prepared according to the construction standards of the Korea Expressway Corporation. Segregation resistance, compressive strength, frictional resistance stress, scanning electron microscope images, porosity, and economic feasibility were analyzed. It was found that segregation effects due to expansive additive incorporation were insignificant, and it was confirmed that all specimens exceeded 0.5 N/mm<sup>2</sup>, the compressive strength standard of the Korea Expressway Corporation pile bearing capacity. Given a water–binder ratio of 83% mixed with 10% expansive additives, frictional resistance increased up to ~35%, skin friction force was significantly improved, and a cost-saving effect of up to ~33.24% was achieved.Hyeonggil ChoiTaegyu LeeHeesup ChoiKangsoo LeeDong-Eun LeeMDPI AGarticlebored pilecement milkexpansive additivesskin friction forcefrictional resistanceTechnologyTEngineering (General).
