摘要： PURPOSE:To enable improvement of a surface layer of the concrete structure into a good formation and to improve adhesive strength of a concrete structure to a matter to be stuck, by a method wherein framing is performed by the concrete form work lined with a sheet whose surface is of an uneven state and water absorbing properties, concrete is placed within the concrete form work and marks of unevenness of a water absorbing sheet are molded on the surface of the concrete. CONSTITUTION:A concrete form work 1 is manufactured by fixing an odd-shaped water absorbing sheet 3 to a concrete form work surface of a form work body 2 by making use of a fixing pin or nail, and the concrete form work 1 is mounted by facing on a longitudinal direction of an abutting position becoming an expected surface of a joint surface of deposition. Concrete 4 is placed within the concrete form work 1, vibration is applied to the concrete 4 and the concrete 4 is tamped by pushing the concrete 4 with a push rod. Then the expected surface of a joint of the concrete 4 is molded into an uneven state by following after unevenness of an odd-shaped water absorbing sheet 3 of the concrete for work 1. Surplus water which comes up to the surface of the expected surface of the joint of the concrete 4 is absorbed by the odd-shaped water absorbing sheet 3 and collected. In addition, bubbled which come up to the surface of the expected surface of the joint of the concrete are discharged outside of the concrete form work 1 through a microscopic hole 31 group of the odd-shaped water absorbing sheet 3 and a surface layer part of the expected surface of the joint of the concrete 4 is improved into a favorable formation where water-cement ratio is high.

摘要： PURPOSE:To form the surface of concrete in good quality by collecting surplus bleeding water and bubbles, by making use of a water absorbing concrete form work where a water absorbing sheet composed of a laminated body of a high water-absorbing sheet, long fiber and air permeable sheet is stuck to the inside of the concrete form work. CONSTITUTION:A water absorbing sheet 4 is composed of a laminated body of a sheetlike high water-absorbing sheet 1, long fiber 3 and air permeable sheet 3. The water absorbing sheet 4 is stuck to the face of a concrete form work 5 by using a nail or a pin or a double-side tacky tape. In this instance, an air permeable sheet 3 constituting the water-absorbing sheet 4 is fitted to the concrete form work 5 by facing toward the inside of the concrete form work 5. Concrete 6 is placed within the concrete form work 5. The concrete 6 is tamped while accelerating rising of bleeding water and bubbles by vibrating the concrete 6. The major part of the surplus water and bubbles are collected by the high water-absorbing sheet 1 and the bubbles permeated through the high water-absorbing sheet 1 are discharged through fine holes 31 of the air permeable sheet 3. A water-cement ratio of a surface layer part of the concrete is lowered, strength and durability of the surface layer of the concrete are improved and the concrete can be finished in good quality.

摘要： PURPOSE:To improve the strength exhibiting property of a special cement-based blend as well as to ensure a long flowability retention time by adding ultrarapid- hardening cement and a setting controlling agent to the blend. CONSTITUTION:Portland cement is kneaded with water, aggregate and an admixture to obtain a cement-based blend. Ultrarapid-hardening cement is added to the blend by >=25wt.% and a setting controlling agent for regulating setting time is further added by 1.5-2.0wt.% of the amt. of the ultrarapid-hardening cement.

摘要： PROBLEM TO BE SOLVED: To provide a method for installing a panel which can be accurately installed in a short time.
SOLUTION: In this method for installing the panel 1 for being installed inside the tunnel undergoing steel lining 5, holders 4 are attached to the steel lining 5 at intervals in a depth direction; a bar 2 is installed between the holder 4; and a fixture 3, which is provided in the panel 1, is fitted into the bar 2. The panel 1 is installed via the bar 2, so that it can be unnecessary for the holder 4 to be attached to each of the fixtures 3. In addition, workability is enhanced because the fixture 3 has only to be attached while attention is paid only to a circumferential position in the tunnel.

摘要： PURPOSE:To produce high quality concrete with a reduced amt. of unit water and superior workability by adding fine powdered materials to cement, water, fine aggregate and coarse aggregate as constituent materials so as to fill the gaps among the constituent materials. CONSTITUTION:Constituent materials of concrete, mortar or cement paste, e.g., cement, water, fine aggregate and coarse aggregate are charged into a mixer. At the same time or after the charge, fine powder of a particle size proper to fill the gaps among the constituent materials, e.g., fly ash powder, slag powder, stone powder, diatomaceous earth, microsand, clay sand or silica sand is charged. They are kneaded for a prescribed time to obtain high quality concrete having a low breathing rate and superior compressive strength.
