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.

Recently, as the national policy of green growth is promoted, construction field also makes an effort to reduce CO₂ gas released when producing cement continuously. In other words, as the method solving environmental pollution and resources exhaustion, lots of mineral material compounds such as blast furnace slag powder which is industrial by-product, fly ash, red mud, etc. are examined to bo used as the substitute good of cement Therefore this study is to investigate the hardening characteristics of alumino-silicate inorganic binder using red-mud used as a accelerator of industrial by-product such as fly ash and blast furnace slag powder according to curing temperature. As a result, it is effective to use red-mud as the accelerator of inorganic binder with other additory accelerators.

In this study, moisture absorption coefficient and efflorescence properties of Ordinary Portland cement and alkali-activated slag cement mortar were assessed according to their red mud substitution ratio. Tests were conducted to determine the cause of efflorescence, which is a significant obstacle to the recycling of red mud as a sodium activator in alkali-activated slag cement, and to find a method to control efflorescence.

Color concrete is produced by adding white portland cement and coloring agent. In Korea, colorant added to color concrete is expensive, durability evaluation in external environment is not verified and there is a tendency to avoid color concrete pouring. Red mud with a water content of 50% was prepared in liquid form using appropriate mixing water and additives for recycling as a coloring agent, the liquefied red mud manufactured was intended to show the possibility of using color concrete. In this paper, the application of red mud as an industrial by - product as a coloring agent for color concrete was investigated for the practical use of liquefied red mud by liquefying red mud and producing retaining wall block. As a result, it was found that all of the specifications stipulated in SPS-KCIC0001-0703 are satisfied.

The Study has analyzed the overall material properties, the measurement of forming colors and applicability of color concrete through making color concrete using red mud heated at 800℃mixed with existing pigment and applying it to the actual field. As the results, the slump flow and aeration meet the target value and the compressed strength of the concrete mixed with red mud and pigment is higher than that of the plain. In addition, the measurement of forming colors turn out to be satisfactory and the color forming is excellent. In the field application, the color concrete panel is proved to make sure the beauty of store exits through its various design available.

Interest in indoor air quality is increasing day by day due to various reasons such as industrial development. Because redmud, an industrial subsidiary, contains titanium dioxide, this study evaluated self-consolidation performance with Slump Flow Test, J-Ring Test, and L-Box Test by mixing redmud in a mixture of ultra-high performance concrete, and sought the optimal combination with high flowability. In addition, the UHPC mixing experiment with photocatalyst was conducted, and the photocatalyst was replaced by the weight ratio of cement and the redmud by the weight ratio of fine aggregate and mixed with the concrete mixture.

In this paper, the compressive strength characteristics of cement paste were compared with the addition of liquefied red mud with the addition of nitric acid in order to improve the strength of the deteriorated cement. The results showed that the compressive strength with between 7 days and 28 days was greater than that of liquefied red mud. The ratio of daily compressive strength of the liquefied red mud is higher than that of the Plain with a 1 percent addition rate, and the ratio of compressive strength is lower than that of the Plain on the 28 days. Therefore, the compressive strength of neutralization liquefied red mud compared to liquidated red mud was relatively high, and the compressive strength of the red mud was shown to be improved to a level almost similar to that of Plain.

In order to improve the strength degradation of the cement-based material to which strong alkaline liquid red mud was added, the liquid red mud was neutralized with sulfuric acid and added to the cement paste to examine the mechanical properties according to the amount added. As a result of measuring the compressive strength, the strength was higher when the red mud was neutralized with sulfuric acid and added to the cement paste than the cement paste to which the liquid red mud was added. As a result of hydration heat measurement, when red mud was neutralized with sulfuric acid and added to the cement paste, an initial strength higher than that of liquid red mud was expressed.

In this paper, in order to utilize recycled aggregate as an alternative to natural resources in the construction industry, the physical properties of red mud-added soil concrete according to the type of aggregate and amount of binder were reviewed. The results of using waste asphalt concrete as a natural aggregate substitute were SPS-KSCICO- It was found to satisfy the compressive strength standards for parking lots of 001-2006, and its applicability in the construction industry was judged.
