摘要： PROBLEM TO BE SOLVED: To provide a wall member capable of reducing or eliminating maintenance after construction work when a side wall part is constructed at a high place and provide a wall member dispensing with the assembly of a scaffold and a civil engineering construction method using the wall member. SOLUTION: Inner forms 15 are provided across a predetermined interval on an inner side in a floor part 5 while a half precast wall member 1 rises in an end part on an upper face side 5B in the floor part 5. A scattering prevention wall part 2 is provided so as to protrude at a higher position than an upper face of the inner form 15 on an upper end side of the wall member 1. Concrete 4 is poured into a ready mixed concrete pouring space 16 formed between the wall member 1 and the inner form 15 and is hardened to integrate the concrete 4 with the wall member 1 so as to form a side wall part 3. Even if the concrete 4 tends to scatter outward when the concrete 4 is placed, scattering of the concrete 4 is prevented by the scattering prevention wall part 2 to avoid a danger in a lower part.

摘要： PROBLEM TO BE SOLVED: To easily and surely detect craking, damage or the like of a concrete pile by burrying a detection material of flexible FRP(fiber reinforced plastic) type capable of detecting change in electric resistance value, and arranging a lead of the detection material outside of the pile. SOLUTION: At first, glass fiber is immersed in a resin slurry in which a hardener and carbon powder are mixed so that the carbon powder is immersed in the glass fiber, thereby forming a carbon powder contained glass FRP 2. The glass FRP is coated with an insulative glass FRP, then after it is dried, a lead 4 is bonded by use of paste 3, thereby forming a flexible FRP type detection material 1 composed of the insulating coating. Then, the lead 4 of the material 1 is connected to a constant current power supply, and after a constant current is made to flow in the material 1 from the power supply, change in voltage to be loaded on electrodes at both ends of the material 1 is measured. The measured voltage is divided by a set current value of the power supply to thereby find an electric resistance value.

摘要： PROBLEM TO BE SOLVED: To prevent concrete fragments of a protective wall from scattering to the side of a road as well as preventing an automobile from jumping out to the side of the road when the automobile collides against the protective wall for the road. SOLUTION: This protective wall for preventing the automobile traveling the road, from jumping out to the side of the road is constituted by jointing precast concrete slabs 3 to the outer side face of a reinforced concrete wall 5 against the inner side face of which the automobile collides. The concrete slab 3 is formed by dispersing staple in concrete or embedding a lint net to intermix fiber. The scatter of concrete fragments is prevented by the intermixed fiber even with crack initiation in the concrete. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To eliminate the problem including troubles that particles themselves flocculate with air entrained in powder flocs, unreacted regions with water or incompletely mixed regions arise, coal ash as a principal raw material has poor wettability by water, etc., which result in insufficient hydration bonds after being formed and cured and therefore the low strength of plates because a conventional method for producing coal ash plates by using cement as a binder has not specified a kneading condition before forming or quantities of water and the like. SOLUTION: Compact and high-strength coal ash plates are formed by blending powder particles where cement as a binder is added to coal ash with the necessity minimum added of water, followed by carrying out operations of kneading them and mixing them together under a pressurized condition to perform pressure forming by means of a mold or die and then by curing. Consequently, the usage rate of added coal ash is profitably high and a special additive is economically needless, and compactness and high strength can be secured due to a contribution to cohesion between powder particles by the hydration bonds of cement particles and the pozzolanic reaction of coal ash particles.
