Red mud is an inorganic by-product produced from the mineral processing of alumina from Bauxite ores. the development of alkali-activated slag-red mud cement can be a representative study aimed at recycling the strong alkali of the red mud as a construction material. This study is to investigate the optimum water content, compressive strength, moisture absorption coefficient and efflorescence of alkali-activated slag-red mud soil pavement according to the recycling fine aggregate content. The results showed that the optimum water content, moisture absorption coefficient and efflorescence area of alkali-activated slag-red mud soil pavement increased but the compressive strength of that decreased as the recycled fine aggregate content increased.

This study is to investigate the optimum water content, compressive strength, water absorption and efflorescence of alkali-activated slag-red mud soil pavement according to binder type. The results showed that the optimum water content, moisture absorption coefficient and efflorescence area of alkali-activated slag-red mud soil pavement increased but the compressive strength of that decreased as the redmud content increased.

This study is alkali-activated slag-red mud soil mixed pavement of efflorescence characteristics analysis of mitigation measures is drawn to the red mud substitution rate in accordance with the alkali-activated slag-red mud soil mixed pavement of efflorescence characteristics were exhibited. As a result of alkali-activated slag-red mud soil mixed pavement is more substitution rate increases appeared to efflorescence is increased.

Red mud is an inorganic by-product produced from the mineral processing of alumina from Bauxite ores. the development of alkali-activated slag-red mud cement can be a representative study aimed at recycling the strong alkali of the red mud as a construction material. This study is to investigate the pore characteristics of alkali-activated slag-red mud soil pavement according to the red mud content. The results showed that the porosity of alkali-activated slag-red mud soil pavement increased but the compressive strength of that decreased as the red mud content increased.

In this search, by evaluating the field applicability of soil mixed pavement of Red mud is mixed into the soil mixed pavement field applicability, and tries to present the basic data about the site application of recycling of red mud and low carbon construction material to. As a result, the conventional soil concrete organization standards (SPS-KSCICO-001: 2003) meets the criteria for parking lot, making use of red mud, natural color as well as the natural loess is expressed.

For this study, alkali-activated slag red-mud pavement is manufactured to examine the usability of red-mud as a recycling material in the construction industry. In the compaction curve in terms of the replacement ratio of red mud by binder type, the dry density changed gradually depending on the water content, which implies that there is no distinct difference in compaction according to the replacement ratio of red mud. The compressive strength at 28 days was observed to be 18.9~27.0MPa in ASS, and 18.4~28.8MPa in OPC, showing a similar level between the specimens.
