Concrete component for load-solution erosion long-term coupling action

Abstract

The invention provides a concrete component for load-solution erosion long-term coupling action. A bracket is arranged at each of the two ends of the lower end face of the concrete component; the width of the bracket is equal to the width of the concrete component; a reserved duct is arranged on each bracket; the two reserved ducts are symmetrically arranged; the hole centers of the ducts are located on a same straight line; a container used for containing a corrosive solution is arranged on the upper end face of the concrete component; the container is free from bottom, so that the solution in the container can be in direct contact with the upper end face of the concrete component. The test method for the simple reinforced concrete under long-term load-solution erosion coupling action can be performed, so that the defects of easiness in corrosion and large occupation of the loading instrument in the traditional test method are overcome.

Description

technical field [0001] The invention belongs to the field of durability test of concrete components, and relates to a concrete component used for long-term coupling action of load-chloride corrosion. Background technique [0002] The indoor corrosion test of existing reinforced concrete members in the chloride salt environment generally adopts the method of immersion in a salt water pool or dry-wet cycle, and the effect of load is seldom considered. For some tests that need to consider the coupling effect of load and chloride salt erosion, generally It is also carried out by means of heavy loading, hydraulic loading or mechanical loading. The disadvantages of these methods are: 1) the screw rod will rust in the chloride salt environment, so the test time cannot be too long; 2) the test piece needs to be soaked in the chloride salt solution pool, and the required area of ​​the test site is large; 3) the solution is exposed In the natural environment, the solution evaporates ...
