Zheng Fang, Guangqi Xiong, Zongxuan Shao, Shuai Zhou, Guangfeng Ou, Lei Liu, Michio Suzuki, Chong Wang, Yuya Sakai: Electrochemical Recycling of Recycled Concrete Powder: Selective Recovery of Calcium and Silica to Enable Sustainable Construction Materials, Resources, Environment and Sustainability, Vol. 18, 100182, 2024
We confirmed that using calcium nitrate as the electrolyte achieves high efficiency in electrochemically extracting useful components such as calcium hydroxide from concrete waste.
Lei Liu, Guangfeng Ou, Lei Xu, Naoki Ogiwara, Sayaka Uchida, Huaming Yang, Yuya Sakai: Simultaneous productions of high-purity calcium carbonate and amorphous nanosized silica-rich gel from waste concrete powder by alkaline treatment and carbonation, Journal of Environmental Management, Vol. 372, 123319, 2024
We developed a method to extract high-purity calcium hydroxide and sodium metasilicate with high recovery rates from concrete waste by treating it with alkali after carbonation treatment.
