Abstract:
A new environment-friendly block, called "steel slag hydrated matrix", consisting mainly of steelmaking slag, ground granulated blast furnace slag, fly ash, and water was developed. Steel slag hydrated matrix has the following features: 1) Made from 100% recycled resources, 2) same strength performance as ordinary concrete, 3) excel-lent wear resistance, 4) low alkaline dissolution, and 5) excellent growth habitat for biofouling organisms in marine environments. In repair work at Mizushima Port, Okayama Prefecture, Japan, 150,000 tons of steel slag hydrated matrix material were used. The ease of use in construction and low impact on ecological systems of the new material were confirmed in the course of this work.
