摘要： PROBLEM TO BE SOLVED: To increase a bending strength in addition to a shearing strength by installing multiple 'reinforced wire materials on a reinforced concrete column continuously in the direction of axis of that column and winding high strength fiber reinforced sheets on it. SOLUTION: On the side surfaces of a column 1 of reinforced concrete structure, mounting grooves 1a, are formed continuously in the direction of axis of that column. Also multiple reinforced wire materials 6, formed with reinforcements, PC steel bars, PC steel stranded wires, or FRP reinforcements are fixed into the mounting grooves 1a so that they are installed continuously in the direction of axis of the reinforced concrete column 1. Then high strength fiber reinforced sheets 7 and 7 are wound on the reinforced concrete column 1. By this, not only a shearing strength of the column 1 but also a bending strength can be increased very efficiently and easily. In addition, when the reinforced wire materials 6 crossed in X-shape are installed at the middle part of the column 1, they can function not only as a bending reinforced materials but also as a shearing reinforced material for very reasonable design.

摘要： PURPOSE:To compactly make the sleeve having plural uneven part on the inner face by inserting the core forming a recessed part or projecting part on the outer periphery into the sleeve and compressing the sleeve outer periphery by a roll by driving a wedge in the gap part of the core. CONSTITUTION:The split core 1 having plural projecting or recessed part grooves 2 on the outer periphery and of which core part is of a truncated conical shape is inserted into a sleeve 7. A wedge 4 is driven into the center gap part 3 of the split core 1 to compress the sleeve 7 outer periphery by a roll. Thereafter, the core 1 is taken off by pulling the wedge 4 out to form plural projecting or recessed parts on the sleeve 7 inner face. The sleeve for reinforced joint with uneven part on the inner face is thus made compactly and at low cost.

摘要： PROBLEM TO BE SOLVED: To make a natural rock as harmless against an alkali silica reaction since in the case of breaking the natural rock to make aggregates for a concrete, in many occasion, such aggregates can not be used as the aggregates for the concrete because of the alkali silica reaction, and to open a way of using as the aggregate used for the concrete. SOLUTION: This method for modifying the natural aggregate for the concrete is to heat the alkali silica reactive aggregate with a flux or without flux at a temperature capable of melting at least a part of it and then cooling gradually from that heating temperature for progressing its crystallization.

摘要： PURPOSE:To arrest the reflected wave of an incident radio wave, and prevent the interference of television radio wave reflection by using a synthetic fiber- reinforced concrete curtain wall in a building wall surface, and providing a ferrite tile in the opposed part of a beam steel frame. CONSTITUTION:For example, a vinylon fiber-reinforced concrete curtain wall is constituted by vinylon fiber-reinforced concrete 1 and Aramid mesh 2. The wall may be a glass fiber-reinforced concrete curtain wall, and a ferrite tile 3 or carbon fiber-reinforced concrete is provided in the part opposed to the beam B of the steel framed body of a building. The radio wave incident to the beam steel frame B is absorbed by the ferrite tile 3, and the radio wave incident to the wall surface is transmitted by the synthetic fiber or glass fiber- reinforced concrete to arrest the generation of the reflected wave.

摘要： PURPOSE:To automate management of concrete by instantaneously obtaining water content of the concrete without requiring hands. CONSTITUTION:A resistance value and an electrostatic capacity of a ceramic element 5 for constituting a ceramic humidity sensor 1 are detected by fetching a detection signal to be output from the sensor 1 buried in concrete 4, and a temperature of the sensor 1 is detected by a temperature sensor 2 buried in the vicinity of the sensor 1. Constants Ar, Er, Ac, Ec of water contents stored in a memory 12 are read based on the temperature obtained by the detecting operation, and then water content W of the concrete 4 is calculated from the resistance value and the capacity of the element 5 by using an Arrhenius equation.

摘要： PURPOSE:To provide the title aggregate for concrete capable of developing strength and capable of removing excess water by forming a protective film consisting of the polymer to be disintegrated by the hydrolysis in water or an aq. alkaline soln. on the surface of a dried aggregate. CONSTITUTION:The protective film consisting of a polymer (e.g., polylactic acid and polyglycolic acid) to be disintegrated by the hydrolysis in water or an aq. alkaline soln. is previously formed on the surface of the dried aggregate for concrete. The dried aggregate having the protective film is used as a part or the whole of the aggregate, and mixed with cement, water, etc. The cement is set at a placing position. In the process of the setting at the placing position, the excess of water over the water amt. to be used in the hydration of cement is used for the disintegration of the protective film and absorbed by the dried aggregate, and the excess water can be removed.
