The invention discloses a loading test device and a loading test
system for testing a
chloride ion permeation law in a concrete test piece, and belongs to the field of concrete tests, the loading testdevice comprises an outer check ring, an inner pressing ring, a conical pressing sleeve, a plurality of wedge-shaped pressing blocks and a pressing device;the inner pressing ring has elasticity, a concrete test piece is fastened between the inner pressing ring and the outer check ring to restrain the
permeation direction of a
chloride ion solution, the conical pressing sleeve coaxially penetratesthrough the inner pressing ring, an axial through hole is formed in the conical pressing sleeve, and the multiple wedge-shaped pressing blocks are evenly distributed between the inner pressing ring and the conical pressing sleeve in the circumferential direction. A pressure-bearing taper hole defined by the wedge-shaped side walls of the multiple wedge-shaped pressing blocks is matched with the conical pressing sleeve, and the pressing device is used for pressing the conical pressing sleeve into the pressure-bearing taper hole so as to apply a radial load; the loading test
system further comprises a
strain gauge and a
signal test analysis system. The device is simple in structure, the concrete test piece can be pressurized through simple operation, and the test of the
chloride ion permeation law in the concrete test piece is facilitated.
