Title:
REBAR CORROSION PROMOTION TEST METHOD AND TEST DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/070144
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a novel rebar corrosion promotion test device that can produce iron rust with a composition which is the same as that of iron rust produced in a real environment as simply and in as short a time as possible without altering the properties of concrete. This rebar corrosion promotion test device is characterized in that: the rebar corrosion promotion test device is provided with a pressurization chamber used for increasing oxygen supply quantity and an oxygen supply device or oxygen pressurization device for increasing oxygen pressure inside the pressurization chamber; a cement paste test body, a mortar test body, or a concrete test body is placed in the pressurization chamber; and the oxygen supply quantity to the interior of the cement paste test body, the mortar test body, or the concrete test body is increased by raising the oxygen pressure in the pressurization chamber.
