Hydration, microstructure and autogenous shrinkage behaviors of cement mortars by addition of superabsorbent

Beibei SUN, Hao WU, Weimin SONG, Zhe LI, Jia YU

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 5,   Pages 1274-1284 doi: 10.1007/s11709-020-0656-x

Abstract: Superabsorbent Polymer (SAP) has emerged as a topic of considerable interest in recent years. The present study systematically and quantitively investigated the effect of SAP on hydration, autogenous shrinkage, mechanical properties, and microstructure of cement mortars. Influences of SAP on hydration heat and autogenous shrinkage were studied by utilizing TAM AIR technology and a non-contact autogenous shrinkage test method. Scanning Electron Microscope (SEM) was employed to assess the microstructure evolution. Although SAP decreased the peak rate of hydration heat and retarded the hydration, it significantly increased the cumulative heat, indicating SAP helps promote the hydration. Hydration promotion caused by SAP mainly occurred in the deceleration period and attenuation period. SAP can significantly mitigate the autogenous shrinkage when the content ranged from 0 to 0.5%. Microstructure characteristics showed that pores and gaps were introduced when SAP was added. The microstructure difference caused by SAP contributed to the inferior mechanical behaviors of cement mortars treated by SAP.

Effect of the addition of organic carbon sources on nitrous oxide emission in anaerobic-aerobic (low

Hongjing LI, Xiurong CHEN, Yinguang CHEN

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 4,   Pages 490-499 doi: 10.1007/s11783-010-0248-4

Abstract: The effect of additional organic carbon sources on the production of nitrous oxide (N O) in anaerobic-aerobic (low dissolved oxygen) real wastewater treatment system was investigated. In this paper, three laboratory-scale sequencing batch reactors (SBRs) (SBR-1, SBR-2 and SBR-3) were operating under an anaerobic-aerobic (low dissolved oxygen, 0.15–0.45 mg·L ) configuration. The SBRs were ‘long-term cultured’ respectively with a single municipal wastewater sample, sodium acetate, and a waste-activated sludge alkaline fermentation liquid as the additional carbon sources of real wastewater. Off-gas analysis showed that N O was emitted into the atmosphere during the aerobic (low dissolved oxygen) period in the three SBRs, and the order of N O emission rate was SBR-2>SBR-1>SBR-3. It was observed that the higher poly-β-hydroxyvalerate fraction of polyhydroxyalkanoates, the lower glycogen transformation and less nitrite accumulation was in SBR-3, while the opposite behavior was observed in SBR-2. Further research indicated that the interaction of the factors above potentially affected the N O emission in the anaerobic-aerobic (low dissolved oxygen) system.
