Abstract

A new environment-friendly block, called “ Ferroform,” consisting mainly of steelmaking slag (corresponds to aggregate), ground granulated blast furnace slag (corresponds to binder) was developed. Ferroform has the same strength and durability as concrete. It can be used a substitute for concrete blocks, natural stones and fresh concrete. In repair work at Mizushima Port, 150 000 t of Ferroform were used as cover blocks and artificial stones.
