摘要： PROBLEM TO BE SOLVED: To provide a method for improving an environment in water or on a water beach, by which excellent effects are obtained for the construction of culture beaches, shallows/zostera-fields/tidelands, the prevention of shore denudation, the prevention of red tides, the prevention of blue tides, and the like, and which can be performed at a low cost and does not cause the damages to organisms and persons with a laying material. SOLUTION: This method for improving the environment in the water or on the water beach is characterized by setting blast furnace air-granulated slag obtained by forming calcium carbonate coating films on the surfaces of the slag particles as an environment-improving material in the water or to the water beach. The blast furnace air-granulated slag has a nearly spherical shape and a smooth surface, is thereby little liable to damage persons and organisms, when laid in the water or on the water beach, has a function for cleaning bottom sediments/water quality due to CaO and a function as a silicate ion-releasing source, hence has excellent performances as the laying material for laying on the water bottom and water beach, and can provide living environments suitable for various organisms including bottom-living organisms living in sands. Since the calcium carbonate coating films are formed on the surfaces of the slag particles, the elusion of sulfur from the slag particles in the early time of construction in water and the pH elevation of water around the slag particles can be inhibited.

摘要： PROBLEM TO BE SOLVED: To create a seaweed bed having a base hardly flowed out by waves, or the like, and preventing the seaweeds from being extracted from the base even if strong water stream caused by the waves, or the like, acts thereon.
SOLUTION: The seaweed bed is formed by laying a blast-furnace water-granulated slag having calcium carbonate films formed on the surfaces of the slug granules, or a mixture thereof with other bottom sediment-constituting materials on a sea bottom to form the base for attaching the underground stems or roots of the seaweeds, and inserting/proliferating the seaweeds in the base. The blast-furnace water-granulated slag has extremely larger stability in the sea compared to that of sea sand to extremely reduce the flowout caused by the waves, or the like, and further has high sear strength to cause strong force of constraining the seaweeds against the waves, or the like, to enable the underground stems and the roots of the seaweeds to twine around the base. As a result, the base itself is hardly flowed out by the waves, or the like, and the seaweeds are prevented from being extracted from the base even if the strong water stream caused by the waves, or the like, acts thereon. The problems of the elution of sulfur and the increase of pH of water at the initial time of laying the slag are properly evaded by using the blast-furnace water-granulated slag having the calcium carbonate films formed on the surfaces of the slug granules.

摘要翻译：要解决的问题：为了制造具有几乎不会由波浪等流出的基部的海床，并且即使由于波浪引起的强水流等也防止了海藻从基部抽出，在其上行事。解决方案：海藻床是通过在海底上铺设形成在颗粒颗粒表面上的碳酸钙膜或其混合物与其它底部沉积物构成材料形成的高炉水粒状炉渣而形成的用于连接海藻的地下茎或根的基础，以及将海藻插入/增殖在基部中。高炉水粒状炉渣与海砂相比具有极大的稳定性，极大地减少了由海浪引起的流出等，并且进一步具有较高的抗冲击强度，从而产生强烈的约束海藻的力波浪等，以使地下茎和海藻的根部绕着基部缠绕。结果，即使由波浪等引起的强水流等作用，基部本身也不会被波浪等流出，并且防止了海藻从基部抽出。通过使用在渣块颗粒表面上形成的碳酸钙膜的高炉水粒状炉渣，适当避免硫酸溶出的问题和炉渣初始时的pH值增加。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method for improving an underwater or an environment of a water shore which can carry out at a low cost against withered seashore or red tide bearing fear in certain ocean space and against bearing fear in relation toes, such as certain ocean space, about ebb and extinction of marine algae growth milieu by causes other than withered seashore, which inhibits growth of withered seashore or red tide and which can acquire efficacy excellent in reclamation of seaweed bed, repairs of marine algae growth milieu, and the like. SOLUTION: Granulated blastfurnace slag on which calcium carbonate coated cap was formed such as a source of silicate ion shedding, to underwater is installed. Thus, since the granulated blastfurnace slag is excellent in the elution nature of the silicate ion, the silicate ion emitted underwater from the granulated blastfurnace slag can proliferate the marine algae. As its result, growth of withered seashore or red tide can be suppressed. Also, growth of hydrogen sulfide leading to blue tide growth and eutrophication of seawater can also be controlled. Further, since calcium carbonate coated cap is formed on the surface of granulated blastfurnace slag particle, pH elevation due to elution of S from slag in submergement virgin and that in surrounding water of slag particle can also be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a method for improving the environment especially in water, shallow water/tidal flat, etc., to form an environment suitable as a habitat of organisms by using a laying material available in large quantities at a low cost. SOLUTION: Granulated blast furnace slag containing ≥90 mass% slag particles having a particle diameter of ≥0.5 mm and preferably ≥70 mass% slag particles having a particle diameter of ≥1.0 mm is laid on sea bottom or on a beach. Granulated blast furnace slag has the nature/appearance close to those of natural sand, exhibits chemical action to clean the bottom and water and functions as a silicate ion releasing source and, accordingly, it is suitable as a laying material. Furthermore, the slag has a controlled particle size distribution, it can form a sea bottom suitable as a habitat of bottom organisms. A safe beach is formed owing to extremely small content of needle-like particles. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a submerged breakwater capable of maintaining a stable structure over a long period of time, while providing a water quality purifying and sludge deposit restraining effect. SOLUTION: This submerged breakwater is constructed by stacking steel manufacturing slag having a rate of a slag mass having a particle size of 100 mm or more being 60 mass % or more and a rate of a slag mass having a particle size of 30 to 300 mm being 95 mass % or more on the water bottom. The submerged breakwater effectively exhibits the original water quality purifying action of the steel manufacturing slag by preventing the deposit of sludge in a slag clearance, and can further provide the water quality purifying action and the sludge deposit restraining effect by the fixation and activity of an organism by forming an environment suitable for the organism inside. The submerged breakwater properly prevents the wash-away of the slag and the collapse of the submerged breakwater by external action such as waves and the buoyancy of epiphytic seaweed, and maintains the stable structure over a long period of time.

摘要翻译：要解决的问题：提供能够长时间保持稳定结构的浸没式防波堤，同时提供水质净化和污泥沉积抑制作用。解决方案：该浸没防波堤是通过将具有100质量％以上的粒径为100质量％以上的炉渣质量和具有粒径为30的炉渣质量的钢渣制造炉渣堆积而成的至300mm，在水底上为95质量％以上。淹没防波堤通过防止污泥在渣渣中沉积，有效地展现了钢铁制造渣的原有水质净化作用，并可进一步通过生物固定和活性提供水质净化作用和污泥沉积抑制作用通过形成适合内部生物体的环境。淹没的防波堤通过外部作用（如波浪和附生海藻的浮力）正确地防止了炉渣的洗涤和淹没的防波堤的崩溃，并且长期保持了稳定的结构。版权所有（C）2005，JPO＆NCIPI
