Bauxite Residue and Utilization

In the Shikoku area, it is eager to request an alternative fine aggregate in stead of natural sand, in particular sea sand, by the reason of prohibition of borrowing sea sand in Seto Island Sea. In this study, the fundamental properties of concrete using copper slag (JIS A 5011-3) or second class fly ash (JIS A 6201) as a part of fine aggregate to apply for plain concrete structure is investigated. It is concluded that the concrete of 20 mm in coarse aggregate maximum size, 50% in water-cement ratio and 40 mm in coarse aggregate maximum size, 60% in water-cement ratio and up to 30%, except in the case of 50% in water-cement ratio of fly ash concrete is possible to 20%, at in volume percentage of sand using copper slag or second class fly ash is applicable for concrete structure.
