摘要： PROBLEM TO BE SOLVED: To provide a crack detecting method that can detect cracks of minute width even when image data of a concrete surface is of low resolution.
SOLUTION: The crack detecting method includes: a first step of creating a wavelet image; a second step of creating a crack extraction image; a third step of creating a thinned image, extracting two large and small wavelet coefficients out of wavelet coefficients corresponding to the thinned image, and setting relatively large crack width and small crack width corresponding to the two wavelet coefficients; and a fourth step of estimating a crack width by substituting the wavelet coefficient corresponding to the thinned image, in a first relational expression composed of the two wavelet coefficients and the relatively large crack width and small crack width.

摘要： PROBLEM TO BE SOLVED: To detect a defect in a coated reinforcing bar after concrete is placed. SOLUTION: In a concrete structure 1 in which a reinforcing bar 3 coated with an epoxy resin 2 is buried, a conductor 4 for detection is connected to the reinforcing bar 3 coated with the epoxy resin 2. The end part of the conductor 4 for detection is exposed on the surface of the concrete structure 1. The conductor 4 for detection is connected to a potentiometer 5, and an electrode 6 for collation is connected separately to the potentiometer 5. Then, the collation electrode 6 is brought into contact with the surface of the concrete structure 1, and a defect is detected.

摘要： PROBLEM TO BE SOLVED: To provide a simple decision method for specifying the strength range of concrete structure. SOLUTION: In the decision method for specifying the strength range of a concrete structure, a concrete core is sampled from a concrete structure and relative hardness at a micro part of cement paste is measured from the top surface of the concrete core toward a deep part. Strength range of the concrete structure is specified from the top surface of the concrete core to a deep part by processing the measurements statistically.

摘要： PROBLEM TO BE SOLVED: To execute objective and reproducible evaluation and prediction by clearing up the corrosion condition of a reinforcing bar in concrete only from a phenomenon observed by a real structure so as to exclude a subjective judgement by an investigation stuff. SOLUTION: The depth of carbonation easily obtained by investigating the real structure is positioned as a sensor monitoring the using material, mixing, execution, using environment, using period, etc., of concrete and this is made an index indicating the shifting of oxygen being one of the corroding factors of reinforcing tears. Thereby the corroding degree of the reinforcing bar in the real structure in environment including a chloride ion being the destroying factor of a passive-state coat is evaluated by restricted investigation data. Basically, the covering of concrete, the depth of carbonation and the quantity of all the chloride at the position of the reinforcing bar are are set to be the corroding factor of the reinforcing bar and this is added with an environmental temperature, an environmental humidity and a yearly precipitation among such general environmental conditions as is published by the Central Meteorological Observatory and the situation of the surface of the structure at the time of investigation to visually evaluate the corrosion rate of the reinforcing bar.

摘要： PURPOSE:To naturally collapse a block and to prevent the burying of a dam and the lowering of a river bed at a downstream by using a deposited sand collected at the upstream as an aggregate, adding a binder, cement, admixture, etc., to the aggregate to obtain the block easy to collapse and arranging the block on the downstream side of the dam. CONSTITUTION:A deposited sand collected on the upstream side of a dam is used as an aggregate, the aggregate is mixed with a binder (e. g. converter slag), cement and an admixture (e. g. methylcellulose) or mixed with cement and a crushing material (e. g. sodium sulfate) to form a concrete block easy to collapse. The concrete block is arranged at a place on the downstream side where the water current is easily collided. Water is infiltrated into the block to gradually and naturally collapse the block into sand which is allowed to flow toward the downstream side.
