The microstructure and NOx degradation ability of alkali-activated steel slag-based pervious concrete doped with g-C3N4/CoAl-LDH
No full textA new nanocomposite g-C3N4/CoAl-LDH was synthesized and implemented to make alkali-activated steel slag-based photocatalytic pervious concrete (ASSPPC). The water permeability, compressive strength, microstructure, and NOx degradation ability of ASSPPC were investigated. The results show that at lower dosages (1 wt% and 3 wt%), the spherical structure facilitates excellent dispersion of g-C3N4/CoAl-LDH within the matrix, which leads to reduced matrix porosity, resulting in improved compressive strength and reduced water permeability in ASSPPC. Compared to control previous concrete, the compressive strength of ASSPPC with 1 wt% g-C3N4/CoAl-LDH increased by 6.3%, and water permeability of which decreased by 15.4%, respectively. However, at higher dosages (5 wt%), g-C3N4/CoAl-LDH tends to agglomerate, causing lower hydration degree and higher matrix porosity. Moreover, owing to the remarkable alkali resistance of g-C3N4/CoAl-LDH, ASSPPC with this photocatalyst only marginally decreases its NOx degradation ability as the curing age increases. When considering water permeability, compressive strength, and NOx degradation ability, ASSPPC with 3 wt% g-C3N4/CoAl-LDH demonstrates optimal performance, which gives both compressive strength and water permeability equivalent to pervious concrete without photocatalyst while exhibiting a NOx degradation rate 0.58 times higher than that of ASSPPC with 3 wt% g-C3N4
Spatial Chow-Lin Methods for Data Completion in Econometric Flow Models
Full text linkFlow data across regions can be modeled by spatial econometric models, see LeSage and Pace (2009). Recently, regional studies became interested in the aggregation and disaggregation of flow models, because trade data cannot be obtained at a disaggregated level but data are published on an aggregate level. Furthermore, missing data in disaggregated flow models occur quite often since detailed measurements are often not possible at all observation points in time and space. In this paper we develop classical and Bayesian methods to complete flow data. The Chow and Lin (1971) method was developed for completing disaggregated incomplete time series data. We will extend this method in a general framework to spatially correlated flow data using the cross-sectional Chow-Lin method of Polasek et al. (2009). The missing disaggregated data can be obtained either by feasible GLS prediction or by a Bayesian (posterior) predictive density.Missing values in spatial econometrics, MCMC, non-spatial Chow-Lin (CL) and spatial Chow-Lin (SCL) methods, spatial internal flow (SIF) models, origin and destination (OD) data
