  • In this study, we investigate the difference of concrete between natural aggregate and electric are furnace(EAF) slag one in oder to use EAF slag aggregate as coarse aggregate in concrete. We find the physical and chemical properties of EAF slag aggregate for the aging process. We consider the properties od the concrete made with EAF slag aggregate which are compressive strength, splitting tensile strength and modulus of elasticity.

  • This experimental study was carried out to estmate the effects of mixing dosage rate and blain on the compressive strength properties of antiwashout underwater concrete admixed with finely ground granulated blast furnace slag. The experimental parameters are slag contents(0, 20, 30, 40, 50, 60%). As a result the compressive strength have a high correlation with slag blended ratio. Thus, it is possible to calculate the modulus of modified age using compressive strength of antiwashout underwater concrete blended with slag.

  • In this study, we investigate the difference between natural aggregate and electric arc furnace (EAF) slag one in order to use EAF slag aggregate as coarse aggregate in concrete. We find the physical and chemical properties of EAF slag aggregate according to the different aging processes. We consider the properties of the concrete made with EAF slag aggregate on these bases.

  • Blast furnace slag powder(BFS) is potential hydration material, and that usage is increased the construction. But, the amount of BFS is important factor with the properties of concrete. The determinational method of slag powder experiments by salicylic acid-methyl alcohol solution method. From these results we can determine the amount of slag powder with blaine 4, 000 and 6, 000 in fresh concrete.

  • Natural stone causes environmental pollution when it is collected and processed. Also, it is hard to make consistent products. Therefore, this study focuses on the artificial stone with waste porcelain to replace natural stone. The flexural strength and compressive strength are lower according to the replacement ratio of blast furnace slag in the result of experiment.

  • Blast Furnace Slag Powder is potential hydration material, then that is well known to evidently inferior early strength, in fact because of feeble solidify. So this experience is that Blast Furnace Slag Powder as 4000, 6000, 8000$\textrm{cm}^2$/g of blain as 15, 35% of replacement ratio, SO3 is maxed as 0.5, 1.0% of binder ratio for intention to increase of strength.

  • Application of Blast Furnace Slag Powder in concrete as brisk in the world, and study in it is progressing in korea at most recent. When use Blast Furnace Slag Powder to concrete, there are profits that is minigation of hydration heat, increase late strength, increase of chemical resistancy, and superior effect on mobility because of powder single phase is over 4000$\textrm{cm}^2$/g blain is known to experience.

  • Recently, the use of the underwater concrete constructions with the antiwashout underwater concrete is increasing. In this study, we investigate the properties of pH, suspended solids, slump flow, box test, air contents of fresh antiwashout underwater concrete and the Unit weight, compressive strength of hardened antiwashout underwater concrete which Ground Granulated Blast Furnace Slag contents 0%, 10%, 20%, 30%, 50%, 60% at 7days and 28days age which is produced and cured in the water and sea water. As a result, Ground Granulated Blast Furnace Slag contents 30% was excellent.
