The reuse or recycle of waste materials is one of the most important problems in developed countries. The study is focused on the reutilization of the waste concrete powder, which is a by-product of recycling the waste concrete. This concrete powder is produced (about 30% in weight of original waste concrete) when the waste concrete is crushed and the aggregates are sieved away. The objective of this research is to clarify the possibility of the practical use of the cement hardened concrete powder. The treated samples were subjected to the following tests an unconfined compression test, an X-ray diffraction analysis, a scanning electron microscope observation, etc. As the result, a large hardening effect was noticed when a small amount of the carbonated aluminated salt material is added to the cement, compared with the case of only cement mixing. The strength change during the subsequent hydration is then discussed. According to this procedure, the stabilized waste concrete powder can be applied as a soil stabilizer and/or a grout material.
