| 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-Ju region and the artificial light weight aggregate which the high temperature(1100℃) 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 Slump and Air contents are tested in fresh condition, the compressive strength, tensile strength are tested in hardened condition. From the results of experiment, the use of garnet is expected to improve the workability and the strength of concrete. Also, this paper is to development and application the high-strength lightweight concrete with lower than 2.0tf/m3 of unit weight and over then over then 350kgf/cm2 of compressive strength. |
