This study is to investigate the possibility of using recycled EPS ingot as fine aggregate and to set basic data of the efficient mixing design for making lightweight concrete.
The condition of the most efficient mix design for making lightweight concrete is that under the replacement ratio of 100%, if cement content is 400㎏/㎥ W/C ratio is 55%, if cement content is 450㎏/㎥ W/C ratio is 50%, 55%. From the result of the experiment under conditions, we could make the concrete whose qualities are slump value of over 18.2㎝, unit weight of less 2.00t/㎥, and compressive strength of over 222.57㎏f/㎠ when the cure duration is 28 days.
