摘要： PROBLEM TO BE SOLVED: To provide a high-strength concrete composition having desired performances.
SOLUTION: The composition has a water/cement ratio of 20-40% and a unit quantity of water of 120-185 kg/m
3 and contains 0.1-3.0 pts.wt. admixture per 100 pts.wt. cement. The admixture is a reaction mixture obtained through the following first and second steps and/or first, second and third steps. In the first step, in a non-aqueous system, in the presence of a non-aqueous radical polymerization initiator, radical copolymerization of a radically polymerizable monomer mixture containing maleic anhydride and a specific allyl ether monomer in a prescribed ratio is initiated. In the second step, the radical copolymerization is stopped in the middle of the reaction by addition of water to the reaction system when the polymerization conversion rate reaches 50-90%, and the reaction mixture containing the resulting copolymer and the remaining monomer is obtained. In the third step, the reaction mixture is partially or completely neutralized to obtain a partially or completely neutralized product of the reaction mixture.

摘要： PROBLEM TO BE SOLVED: To provide a packaged material facilitating the charge of a prescribed amount of fiber, especially a small amount of fiber such as a rupture-preventing fiber for high-strength concrete into concrete in a concrete agitator car, etc., and uniformly kneading the fiber into the concrete without necessitating a particular equipment and dispensing with the metering procedure to impart the concrete with a function such as rupture-preventing property by the material constituting the packaging material and to provide a process for producing a fiber concrete having stable quality by using the packaged material. SOLUTION: The packaged material is produced by packaging single fibers composed of synthetic fibers with a packaging material comprising a sheet produced by integrating staple fibers composed of synthetic fibers with a polymeric substance dissolving or disintegrating in water or in an alkaline solution. The fiber concrete is produced by throwing the packaged material into a cement mixture and stirring the mixture to break the packaging material and uniformly mix the staple fibers composed of synthetic fibers into the cement mixture.

摘要： PROBLEM TO BE SOLVED: To reproduce conditions approximating the natural state and to evaluate the resistance to pollution, in a short time, by repeating the spraying of a dust material to a sample and a plate provided above the sample and the sprinkling to the portion of the plate. SOLUTION: The pollution progress test of a material, such as concrete used for the outer wall of a house or a building, is conducted by using, for example a test body 3 fitted with a plate 2 simulating a window and made of a plastic which is easily stuck by dust above a sample 1. A water sprinkling 4 to the plate 2, spraying of a dust material with the prescribed composition on the faces of the sample 1 and the plate 2, and drying are repeated for the process with the test body 3 fitted to a rotating frame, for example. The color of the surface of the sample 1 is measured before and after the process to obtain luminosity difference, and the level of dust pollution of the sample 1 is decided. Since water sprinkling is applied to only the portion of the plate 2, the difference caused by the magnitude of the water absorption coefficient of the sample 1 and the level of the hydrophilic/water repellent property of the surface can be clearly evaluated.

摘要： PURPOSE:To easily manage the quality of high strength concrete by measuring the settlement of concrete in a reservoir part, or the moving amount of concrete in a flow part, and the drift velocity of concrete. CONSTITUTION:At the time of executing a quality test of concrete, a vertical part 10 is filled with concrete of a prescribed quantity in a state that an opening 16 has been closed by a partition plate 14, and subsequently, by drawing up the partition plate 14, concrete is allowed to flow to a horizontal part 12 from the opening 16. In this case, a time point when a deformation of concrete is started is a time point when the partition plate 16 has been drawn up, and a time point when the deformation of concrete is ended is a time point when the movement of concrete in the horizontal part 12 has stopped, and both of them can be discriminated clearly. In this state, by measuring a moving amount of concrete in the horizontal part 12 at the time point when the deformation of concrete has been ended, a yield value is derived. Also, by dividing the moving amount by the time extending from the time point when the partition plate 14 has been drawn up to the time point when the movement of concrete has stopped, and measuring a drift velocity of concrete, viscosity is derived.
