摘要： PROBLEM TO BE SOLVED: To obtain a resin concrete containing a small amount of a blended resin while maintaining excellent executability and strength by blending an aggregate with a binder and a filler and specifying the oil absorption volume of the filter and the slump value of the concrete. SOLUTION: This resin concrete comprises 50-92 pts.wt. aggregate, 3-60 pts.wt. binder and 5-44 pts.wt. filter. (1) The filter has filler and (2) the slump value of the resin concrete measured by a method according to JIS A 1101 (a testing method for the slump of concretes) is within the range of 12-21cm. The binder is preferably a methacrylate resin. The resin concrete is capable of maintaining excellent executability, strength and durability even when the amount of the resin blended in the composition is small. Thereby, a lower cost of the resin concrete can be realized.

摘要： PROBLEM TO BE SOLVED: To solve the problem that air locks are easy to occur between a rear and the surface of mortar when the rear is laid on mortar because a conventional PC board is formed in a plate shape that both surfaces run parallel and a thickness between both surfaces is formed in an equal thickness although the deteriorated section of existing concrete is chipped, mortar is mounted on the surface of existing concrete, from which the deteriorated section is removed, and the plate-shaped PC board is installed on the mortar when the floor, wall, ceiling or the like of existing concrete is renewed by the PC board. SOLUTION: In the plate-shaped PC board 1 used for a repair by removing the deteriorated section of existing concrete, a surface 2 is formed in a horizontal surface, the rear 3 is formed in a gentle surface and a thickness between the surface 2 and the rear 3 is formed unequally. The rear 3, for example, is formed in a spherical shape 3A that the rear is protruded towards the central- section 4 direction of a surface. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a method for determining the center of an inner circumferential surface of a tunnel prior to scraping a deteriorated portion in an inner circumferential part of the tunnel, a tunnel with a circular cross-section in particular. SOLUTION: This method is used for determining the center of the inner circumferential surface 12 of the tunnel 10. A distance measuring sensor 16 mounted on a front end part of an arm 14 is rotated on an axis RA of rotation to measure the distance from the axis to the surface of the tunnel at three or more positions in the circumferential direction of the tunnel. Then, the position of the axis RA is adjusted based on the results of the measurement so as to agree with the real center axis AA of the tunnel.
