Abstract: In an LNG tank, a dike is formed by arranging precast blocks in the circumferential direction and layering the precast blocks in the vertical direction. Each of the precast blocks has loop joints on the top, bottom, left, and right side faces, and concrete is deposited between each two precast blocks adjacent in the circumferential direction and the vertical direction, whereby masonry joints are formed in the vertical direction and the circumferential direction. Prestress is imparted to the dike by PC steel members. The PC steel members are provided in the circumferential direction and the vertical direction of the dike, and are arranged so as to avoid the masonry joints in the circumferential direction and the vertical direction. Therefore, it is possible to construct the dike in a short time, and it is possible to provide a tank or the like that can reduce the construction period.

Abstract: A method for manufacturing a concrete structure comprises an installation step of installing a formwork 30 for concrete placement, a placement step of performing concrete placement in a state where a curing sheet 10 is attached to an inner surface of the formwork 30, and a demolding step of removing the formwork 30 after placement of concrete C. A contact angle of a contact surface of the curing sheet 10 for use in the placement step with water is 50 degrees or more, wherein the contact surface faces the concrete. Thus, generation of bleeding water is suppressed.

Abstract: In a reaction where a lower hydrocarbon is subjected to direct decomposition by using a catalyst to produce a functional nanocarbon and hydrogen, the lower hydrocarbon is subjected to the reaction in an coexistent gas comprising low concentration of oxidizing gas, reducing gas or a mixture thereof. The precursor of functional nanocarbon produced on the catalyst and amorphous carbon secondarily produced on the catalyst react with the coexistent gas so that being removed from the catalyst, making it possible to prevent the drop of conversion with time on stream due to the inhibition of the reaction by the precursor and by-product. In the case where the raw material of lower hydrocarbon is biogas, the coexistent gas can be easily contained in methane by lowering purification degree of methane.

Abstract: Therefore, the problem to be solved by the present invention is to provide highly general purpose ultra high strength fiber-reinforced mortar or concrete that shows a higher fluidity (workability) at the fresh state, a higher bending strength with a less content of metal fiber by enhancing both the absolute value of the compressive strength of mortar -matrix excluding metal fiber and the ratio of the bending strength relative to the compressive strength simultaneously at the hardened state, and acceptability of fine aggregate being used in ordinary ready-mixed concrete. An ultra high strength fiber-reinforced cement composition is characterized in that it contains cement, silica fume, coal gasification fly ash, gypsum and metal fiber and that the mass ratio of silica fume : coal gasification fly ash is 95 through 50 portions: 5 through 50 portions. Ultra high strength fiber-reinforced mortar or concrete contains such a cement composition and fine aggregate.

Abstract: In monitoring a stratum disposal field for wastes, running tubes installed in the vicinity of a gallery or disposal holes, in a nearby rock bed, or within a gallery support or buffer members in the disposal holes have installed therein a movable monitoring device provided with various sensors, a water sampling device and the like. The monitoring device may be movable or fixed in a predetermined position, for measurement of the temperature, displacement, strain, stress and underground water in connection with the rock bed, the gallery support or the disposal space buffer members. Measurement of the clearances in the rock bed, the gallery support back or the disposal space buffer members is monitored. Also, sampling of underground water in the rock bed, the gallery support or the buffer members is effected, thus reducing the number of sensors, drilled holes, communication cables to facilitate the exchange or maintenance of the sensors, communication cables and the like.
