<p>The present invention provides a high-density concrete composition including a binding material that contains granulated blast furnace slag, desulfurized slag, and plaster; and an aggregate that contains rapidly-chilled electric furnace slag and electric furnace oxidizing slag, wherein 500 to 750 parts by weight of the aggregate is contained with respect to 100 parts by weight of the binding material. Also provided is a breaking-wave block that is manufactured by using the high-density concrete composition. By using the high-density concrete composition of the present invention is used, cement consumption is decreased thereby preventing environmental pollution attributable to carbon dioxide generated during cement production and to an alkali element flowing out of cement; and also, slag aggregate, which is a steel byproduct, is recycled to improve economic efficiency. Moreover, the breaking-wave block with an improved breaking-wave performance is manufactured by using the high-density concrete composition, and thus human and material damage due to natural disasters such as typhoons can be minimized.</p> |
