In Japan, the Basic Law for Establishing the Recycling- based Society was enacted in 2000, which is intended to restrict consumption of natural resources and reduce environmental loads comprehensively and systematically by encouraging the efficient reuse and recycling of resources, and thus help turn today's social framework based on mass production, mass consumption and mass waste towards an environmentally sustainable society. In response to these environmental concerns, the Japanese steel industry is striving to reduce the production of steel slag, which is a byproduct of the process of steel manufacturing, and to conduct R&D on technologies for recycling this slag. The present paper deals with 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. (Copyright JFE Technical report)
