Material for reducing environmental load, development method of isolated island, coral growth base and coral growing method

摘要

Problem to be solved: to provide an environmental load reducing material capable of reducing an environmental load, a development method of an isolated island, a coral growth base and a coral growth method.Solution: an environmental load reducing type material used for construction in a remote island is made up of a material containing a combustion byproduct as a main component.The combustion byproducts were coal ash with an optimum water content of 19% to 40%, and the coal ash had an aging period of 3 months in the optimum water content, and the maximum stress at 7 days of age was 0.01 to 0.3 n \/ mm2 of coal ash alone, and 3% by weight of coal ash was added to coal alone It may be 0.3 to 1.5 N \/ mm2.No selection
