Until now, construction sludge, which has been treated with cement and lime for soil improvement, has been mostly disposed of as industrial waste because its pH becomes highly alkaline, and therefore it has not been effectively utilized.
In recent years, while reducing environmental impact has attracted attention, the effective utilization of construction sludge, which is generated in large quantities in a short period of time due to increasingly large-scale construction projects, remains a critical social issue that cannot be overlooked.
Therefore, we have developed "TM Rock APX," a new neutral soil modifier that utilizes amorphous aluminum and employs a reaction (ettringite) that solidifies immediately in a neutral range and subsequently develops strength.
