Atsushi Iizuka, Auteur ; Yuka Sakai, Auteur ; Akihiro Yamasaki, Auteur |A bench-scale plant for waste concrete sludge recycling was designed, constructed, and operated. Real concrete sludge generated from a pile and pole production plant and groundwater were used for the experiments. The process mainly consists of t[...]

Jiawei Wu, Auteur ; Atsushi Iizuka, Auteur ; Kazukiyo Kumagai, Auteur |Dry desulfurization characteristics of waste cement particles were examined with laboratory-scale experimental apparatus based on the weight change of the sample exposed to a gas flow containing SO2. The waste cement particles, a byproduct of r[...]

Takeshi Sasaki, Auteur ; Yuka Sakai, Auteur ; Atsushi Iizuka, Auteur |Low-crystallinity hydroxyapatite (HAP) was prepared from concrete sludge as a recycling method for concrete waste. The HAP was prepared from model samples of concrete sludge and phosphorus wastewater, and its capacity to remove lead from water w[...]

Jiawei Wu, Auteur ; Atsushi Iizuka, Auteur ; Kazukiyo Kumagai, Auteur |We studied the effect of acid treatments on the desulfurization rate of waste cement, a byproduct in the recycling of aggregates from waste concrete. Calcium components in the waste cement were partially extracted by treatment with carbonic acid[...]

Hiroki Nagasawa, Auteur ; Atsushi Iizuka, Auteur ; Akihiro Yamasaki, Auteur |Bipolar membrane electrodialysis (BMED) was used to remove boron from aqueous solution. BMED was compared with conventional electrodialysis (ED) using aqueous solutions of sodium tetraborate containing 100 mg/L of boron. With use of BMED, more t[...]
