摘要： PROBLEM TO BE SOLVED: To predict the advance of compound deterioration due to salt damage and carbonation in a technique for predicting deterioration in a concrete structure. SOLUTION: The deterioration prediction method of a concrete structure predicts the advance of deterioration due to the salt damage and carbonation of the concrete structure by analyzing various kinds of deterioration factors using a finite element method. The progress of compound deterioration is expressed by a chemical reaction expression including a hydration product in concrete and carbon dioxide in the atmosphere at one side and calcium carbonate at the other side, and a reversible chemical expression containing calcium carbonate, an aluminum acid, and chloride at one side, and Friedel salt and a carbon dioxide gas at the other side. The progress is predicted by analyzing diffusion equations (1) and (2) by finite element method. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To generate a crack in a specific place easily and positively so as to prevent a crack from being generated in an optional direction in an unexpected place. SOLUTION: Three knotless reinforcements 1A, 1B, 1C are embedded in a thin wall part held between joint grooves 21, 21 of a reinforced concrete wall 11, at specified spaces parallel with the joint grooves 21, 21. Within a period from the time of concrete temperature becoming maximum due to heating reaction of hydration until the time of a temperature crack being generated to the reinforced concrete wall 11 by expansion and contraction caused by heating reaction of hydration, a current is applied to the reinforcements 1A, 1B, 1C by an AC power unit 2 to heat the reinforcements 1A, 1B, 1C. Tensile stress vertical to a plane including the reinforcements 1A, 1B, 1C is generated to the thin wall part between the joint grooves 21, 21 of the reinforced concrete wall 11 so as to generate a crack to the thin wall part.

摘要： PROBLEM TO BE SOLVED: To permit to form a large space where no obstacles such as middle columns or intermediate walls exist underneath an arch roof by increasing a strength for supporting a surcharge applied to the arch roof in an underground structure having an arch roof built between continuous underground walls. SOLUTION: In a state where the ends of both sides of an arch roof 2 built between continuous underground walls 1 are connected to both the end portions at both sides of a horizontal structural member 3 made of a slab in one united body, the ends of both the sides of this arch roof 2 and a horizontal structural member 3 are fixed to the ends at the opposite sides of the continuous underground walls 1. In this way, the horizontal structural member 3 functions as the chord of the arch roof 2 and supports the load applied to the arch roof 2 and, even though the thickness of the arch roof 2 is reduced, a large space can be created without obstacles such as middle columns or intermediate walls thereunder.

摘要： PURPOSE: To minimize the adding quantity of a hydration heat-decreasing agent and prevent cracking. CONSTITUTION: The whole placing area D of mass concrete is divided into the first area of concrete 1 without hydration heat-decreasing agent and the second area of concrete 2 with hydration heat-decreasing agent. The placing area L of the second concrete 2 is divided into n areas 11 , 12 ,..., 1n and the initial value of the addition rate in respective layers of the second concrete 2 is a1 , a2 ,... an . The addition rate of the hydration heat-decreasing agent of respective layers of the second concrete 2 is increased gradually by every Δa from the initial value to the upper limit value Amax to get the addition rate of the hydration heat-decreasing agent of the second concrete 2 at the time when the tensile stress of concrete in respective positions, calculated from a temperature-stress analysis is less than the tensile strength of concrete and the addition volume of the hydration heat-decreasing agent becomes minimum.

摘要： PROBLEM TO BE SOLVED: To provide a wall greening panel having high water-retention and enabling easy formation of a greening base on a vertical wall surface without staining the wall. SOLUTION: An irrigation pipe 2, a water-retention mat 7 and a nonwoven holding mat 8 composed of relatively loosely and irregularly entangled nylon strings are placed on the surface of a concrete wall W. The irrigation pipe 2 is placed in a position embedded under the surface of the water-retention mat. The surface of the nonwoven holding mat 8 is pressed against the water- retention mat 7 with anchor bolts 11 and a lath net 10. Soil 13 for greening is sprayed against the nonwoven holding mat 8 with compressed air, etc., to attach the soil to the mat by including the soil into the gap of the mat 8 to easily form the greening base. Since water is slowly and uniformly supplied to the soil through the water-retention mat 7, the partial drying of the soil 13 and the flow out of the soil with the water can be suppressed to enable effective greening of the wall surface and improve the appearance of the wall.
