| Abstract |
In this study, we made the high strength light-weight concrete which was composed of the garnet minute powder to be the industry by-product in the Young-Joo region and the artificial light weight aggregate which the high temperature(1,100 ) plastic process. The concrete`s each unit quantity was determined 145, 160, 175 kgf/m3. W/B and S/A was determined 30%, 43%, 45%. the each admixture`s substitution ratio was determined 0, 10%., and then, the magnesium sulpate resistance, drying shrinkage and thermal properties are tested in hardened condition. ??From the results of experiment, the use of garnet is expected to improve durability of concrete like as the magnesium sulpate resistance and the thermal properties, and drying shrinkage of concrete. |
