This experimental study is the fundamental report to propose the use of waste tile as pozzolanic admixture of concrete. This study performed pozzolan reaction test to examine the possibility of the use. Also, strength development properties and frezze-thaw resistance of concrete containing waste tile were studied. Pozzolan reaction ability test performed through phenolphtalein and condensation setting test. To investigate Strength development properties, waste tile replaced on portland cement in 10, 20, 30, and 40% weight ratios was used. Also this is studied in condition of air containg range of fresh concrete was 2±1%, 4.5±1.5%, 7±1% to investigate frezze-thaw resistance of concrete containing waste tile. The following are the summary of which concluded in this study. In case of waste tile replaced on portland
cement, the proper replacement ratio was 10%. However, considering the concrete cured over 28 days compressive strength, 30% of replacement ratio was higher than plain concrete of that. The results of concrete containing waste tile at the air containing range has similar durability factor when comparing the plain concrete. If concrete containing waste tile has the air containing range 4.5±1.5%, that will have enough resistance against frost action.
