Considering the influence of visible load-induced transverse cracks on chloride ion diffusion in cracked concrete in-service reinforced (RC) elements under marine environment, a typical volume with one crack was taken to establish governing equation. Assuming widths at outer lateral and bottom surfaces were equal, model predict equivalent coefficient put forward consider average width, spacing ...

Pixel-by-pixel spatiotemporal progression of focal ischemia (permanent occlusion) in rats was investigated using quantitative perfusion and diffusion magnetic resonance imaging every 30 minutes for 3 hours. The normal left-hemisphere apparent diffusion coefficient (ADC) was 0.76 +/- 0.03 x 10(-3) mm(2)/s and CBF was 0.7 +/- 0.3 mL x g(-1) x min(-1) (mean +/- SD, n=5). The ADC and CBF viability ...

Calcium chloride (CaCl2) is an inorganic chemical from the group, and it widely used as one of snow removal agents on road in winter. Laboratory experiments were conducted to examine effects salt (NaCl) soil organisms (a animal, microorganisms, plankton). The dwelling Armadillidium vulgare died high concentration calcium treatment. longer processing time A. at chloride, lower survival rate. 16%...

Proton pulsed field gradient (PFG) NMR was used to study the diffusion of poly(diallyldimethylammonium chloride) (PDADMAC) in coacervates formed from this polycation and the protein bovine serum albumin (BSA). Application of high (up to 30 T/m) magnetic field gradients in PFG NMR measurements allowed probing the diffusion of PDADMAC on a length scale of displacements as small as 100 nm in coace...

Chloride ingress is strongly associated with the properties of pores in recycled concrete. To unlock its role chloride permeability, pore structures concrete containing various quantities coarse (fine) aggregates were analyzed from multi-scales, and outcomes further verified by statistical investigation. The results show that different roles played terms concrete, as reflected their volume diam...

Chloride in sweat is an important diagnostic marker for cystic fibrosis (CF), but the implementation of point-of-care systems for diagnosis is hindered by the prohibitive costs of existing chloride sensors. To enable low cost diagnostic solutions, we recently established a citrate-derived synthesis platform for the development of new fluorescence sensors with high selectivity for chloride. As a...

Chloride ion penetration frequently leads to steel corrosion and reduces the durability of reinforced concrete. Although previous studies have investigated chloride permeability some fiber concrete, basalt concrete (BFRC) has not been widely investigated. Considering that BFRC may be subjected various exposure environments, this paper focused on exploring under coupling effect elevated temperat...

A mathematical model is established for chloride penetration in saturated concrete. The model takes into account various influential parameters such as water-to-cement ratio, curing time, types of cement, and aggregate content. Two material models are developed for binding capacity and chloride diffusivity, which have a dominant effect on the chloride diffusion process. The chloride binding cap...
