Description
The present invention relates to a concrete neutralization and crack measurement method using a smart device. In measuring a depth of neutralization of a concrete structure, it is possible to measure by a simple method without breaking a section, and a passive method using a scale The present invention relates to a technique for measuring the neutronization of a concrete structure and a technique for measuring cracks in a concrete using the smart device by measuring the image using an image taking means controlled by a smart device.
Reinforcing steel such as reinforcing steel in a concrete structure does not cause corrosion due to the formation of a passive film on the surface of steel in an alkaline environment, which is a sound concrete. However, the concrete undergoes a neutralization process in which calcium hydroxide produced through the hydration reaction of cement and water reacts with carbon dioxide in the atmosphere and is transformed into calcium carbonate.
When the concrete is neutralized, water and air penetrate through the neutralization part. When the water and air penetrate, the steel becomes the oxidizer 2 iron from the oxidizer 1 iron, causing red rust and corrosion. When the steel is corroded in this way, the volume expands, cracks occur in the concrete, and the strength and durability of the structure are affected by the collapse of the coating of the concrete.
Therefore, the measurement of the depth of neutralization of concrete in structures including steel is a very important test item in relation to the life calculation of concrete structures.
Methods for measuring the neutralization depth of existing concrete are known, such as an indicator method using indicators such as phenolphthalein, a differential thermogravimetric analysis method, and an X-ray diffraction method. However, in general, Phenolphthalein.
The phenolphthalein method is based on the principle of colorlessness in the neutralization region with a pH value of 9 or less and red coloration in a region with a higher pH value than in the case of the neutralization region having a pH value of 9 or less. The alcohol solution of 1% of petroleum phthalate is applied to the cross- And the part not colored with red is judged as neutralized part. The method is a method of measuring 3 to 5 places to the point where the color is discolored, and measuring the average value in the unit of mm .
However, in the phenolphthalein method, as shown in FIG. 1, the cross section of a part to be measured is to be broken by using a drill or the like, so that there is a problem that the appearance of the concrete is damaged. In addition, phenolphthalein is applied by spraying or the like, (Scale), so there is a lot of measurement errors due to the skill of the person measuring the measurement and the angle of measurement. Therefore, there is a problem that the reliability is lowered and the reliability is lowered. There is a hassle to pay an average.
Korean Patent No. 10-0564102 proposes a technology for measuring initial neutrality and measuring neutrality more precisely by measuring indicators of neutrality of concrete by selecting various indicators other than phenolphthalein and selecting indicators . However, this technique also requires only a different indicator to be used, and the concrete cross section must be broken in the same manner as in the conventional phenolphthalein method, and the measurement must be manually performed using a ruler, which makes it difficult to reduce the measurement error.
In addition, Japanese Unexamined Patent Application Publication No. 2008-203275 discloses a technique for forming a perforation having a diameter of about 9 mm in a concrete and inserting an endoscope into the concrete to measure the crack or the depth of neutralization of the concrete. However, this technique is inconvenient because it requires inserting a separate jig to measure the depth of neutralization, and it is very inconvenient and unreliable because it is a manual measurement using a jig. Also, it is inconvenient to process data obtained by using an external large computer to be.
Japanese Unexamined Patent Application Publication No. 2015-72220 proposes a technique of arranging a measuring device equipped with an endoscope in a narrow gap of a concrete structure and moving it in the left and right direction. However, since this technique utilizes reflection using a mirror using a camera of a smartphone, there is a problem that shooting is limited and accurate measurement is difficult.
