Abstract
In this study, laboratory tests were performed to evaluate for new filling materials (ZA-Soil) for bored pile that were developed using by high calcium ash. As a result of laboratory test, the uniaxial compression strength of 2 types of ZA-Soil are shown 68.0% and 64.6% compared to ordinary portland cement. And it have a suitable flowability and environmental stability. Also, after 28days, uniaxial compression strength of material mixed with soil and high strength filling material (ZA-Soil) for bored pile is 1.10-1.23 times bigger than material mixed with ordinary portland cement.
