Utilization of sewage sludge ash in ultra-high performance concrete (UHPC): Microstructure and life-cycle assessment

Yan Xia et al.

Summary: In this research, an economical and eco-friendly ultra-high performance concrete (UHPC) with the dosage of sewage sludge ash (SSA) at 8 wt% was prepared. The addition of SSA has an adverse influence on the workability of UHPC samples due to its special morphology. Furthermore, the microstructure and phase assemblage of SSA-based UHPC were determined and the results show that SSA inhibits the early hydration of cement clinker, while promotes the precipitation of additional hydration products at later curing ages due to its pozzolanic reaction. The pore structure analysis of SSA-based UHPC determined by mercury intrusion porosimetry indicates that the addition of SSA increases the cumulative pore volume, while decreases the large pore volume of UHPC. Economic and environmental analysis indicates that using SSA-based UHPC greatly reduces the unit cost and the impacts on the environment.

Solidification/stabilization of lead-contaminated soils by phosphogypsum slag-based cementitious materials

Zhisheng Ren et al.

Summary: The present study designed a phosphogypsum slag-based cementitious material (PS) and investigated its potential use for solidifying/stabilizing lead-contaminated soils. The physicochemical properties, performance, and mechanisms of lead stabilization in soil were studied using various methods. The results showed that the PS solidified body had acceptable compressive strength for backfill treatments or roadbed materials. The leaching concentrations of lead were within the safety limit specified in Chinese standard, indicating the potential for safe disposal and reuse of PS stabilized soil.

Designing novel magnesium oxysulfate cement for stabilization/solidification of municipal solid waste incineration fly ash

Lei Wang et al.

Summary: An innovative magnesium oxysulfate cement binder was designed for stabilization/solidification of MSWI fly ash, showing excellent immobilization efficiencies for Pb and As. The study found that reactive Si in MSWI fly ash interfered with the MOSC reaction and adversely influenced the immobilization efficiencies of Pb, As, and other elements.

Biochar-augmented carbon-negative concrete

Liang Chen et al.

Summary: This study introduces a new design of biochar-augmented concrete, which promotes cement hydration and enhances the strength of concrete by incorporating biochar as aggregate and supplementary cementitious materials. Life cycle assessment and cost-benefit analysis demonstrate that biochar-augmented concrete can significantly reduce CO2 emissions and generate economic profit.

Designing Magnesium Phosphate Cement for Stabilization/Solidification of Zn-Rich Electroplating Sludge

Yuying Zhang et al.

Summary: The interaction between magnesium phosphate cement (MPC) and zinc oxide (ZnO) in the stabilization/solidification (S/S) process of Zn-rich electroplating sludge was investigated, revealing changes in precipitate chemistry and microstructure transition. The formation of amorphous Zn-3(PO4)(2)center dot 2H(2)O/Zn-3(PO4)(2)center dot 4H(2)O inhibited the formation of Mg-phosphate precipitates.

High-efficiency and low-carbon remediation of zinc contaminated sludge by magnesium oxysulfate cement

Binglin Guo et al.

Summary: This study investigates the use of magnesium oxysulfate cement (MOSC) for stabilizing/solidifying Zn-rich electroplating sludge, showing that Zn was immobilized through chemical interaction and physical encapsulation in the MOSC hydrates. The MOSC system demonstrated superior compatibility compared to Portland cement system, with excellent immobilization efficiency and meeting the requirements for setting time and mechanical strength of sludge S/S products, indicating its effectiveness for treating Zn-rich industrial wastes.
