Axial loading tests of thin-walled circular steel tubes infilled with cast-in-place concrete and precast segments containing DCLs

摘要

A green technique of filling coarsely-crushed demolished concrete lumps (DCLs) and fresh concrete (FC) alternately into steel tubes has been conceived, and realized for years, intended primarily to simplify old concrete recycling. In this study, precast approach is introduced in the foregoing recycling technique trying to improve its applicability.
