A Concrete Contact Dissolution Test Device Considering Splitting Stress

Abstract

The invention discloses a concrete contact corrosion test device considering splitting tensile stress: a computer terminal applies a splitting tensile stress to a concrete specimen in real time through a hydraulic sensor and a gasket, so as to avoid the creep of the concrete specimen after a load is applied once. stress relaxation; the salt solution concentration control device can control and adjust the concentration of the salt solution inside the solution tank in real time; the beam makes the lower surface of the concrete specimen suspended to ensure the consistency of all directions during the corrosion process of the salt solution; after a certain period of time After the splitting stress and dissolution are coupled, the computer terminal can control the stress loading device to measure the durability and mechanical properties of the concrete specimen. The stress loading device adopts lateral loading to avoid the stress caused by the gravity between the specimens, making the test data more accurate.

Description

technical field [0001] The invention relates to a concrete contact corrosion test device considering the splitting stress, in particular to a test device which can be used for comparative research on the durability of concrete after contact dissolution under the action of the splitting stress. Background technique [0002] Concrete panels are often used as anti-seepage structures and widely used in anti-seepage systems and reinforcement projects of earth-rock dams, masonry dams, and roller compacted concrete dams, especially in modern face rockfill dams, most of which use concrete panels as anti-seepage and slope protection structures. Concrete is also widely used as the lining structure in tunnels and tunnels for anti-seepage, protection and reinforcement. Many high concrete face dams have been built in the world. In the next two decades, my country will build many concrete face dams in the western region. The working conditions of these dams are harsh, and the cracks in th...
