The purpose of this study is to analyze the strength development of concrete containing bottom ash as a part of fine aggregate. The experimental program included the measurement of concrete for compressive strength, splitting tensile strength, permeability, dynamic elastic modulus. The results of the experimentation are as follow. The compressive strength of concrete using bottom ash decreased according to increase of the replacement rate of bottom ash. The
highest compressive strength showed at the replacement ratio of 30% bottom ash and 10% fly ash. The concrete containing CSA, CaSO4 as activator was effective on the compressive strength development. But the concrete using NaOH as activator showed a poor characteristic. In the case of using bottom ash, fly ash as fine aggregate, the concrete is waterproofed concrete than ordinary concrete by the pozzolanic effect.
