Composite steel wall structures with concrete have been broadly applied in engineering, and self-compacting concrete with high Pentair EasyTouch Parts fluidity is usually employed for the concrete placement of complex structures.Testing mock-up was established to monitor strain and displacement changes of the external steel plate while pouring concrete.The survey data show that the lateral stress was first Tray shifted from rapid growth to slow decay and then get stabilized, which can be referenced to the design and construction of the composite structure module.
