In this research work, the UHPC's service life can be predicted when exposed to different concentrations of sulfuric acid. When comparing acid and sulfate attacks, the latter becomes negligible. Despite the use of silica fume and fly ash, the reactivity with sulfuric acid ...
2A). At a low flow rate, acidification reactions take place within the biofilm, leading to biodeterioration involving Ca-leaching, formation of secondary non-cementing minerals (e.g., M-S.H and thaumasite) increasing porosity (Fig. 2B). In the event of an increased flow rate, the saline ...
Edible oils, before being ingested, can be used at high temperatures as a sauteed or during the frying process; in this way, the surface of foods that have a protein origin or that have a high carbohydrate content is modified. In the frying process, the chemical nature of the oil deterior...
Potential use of matakaolin as a partial replacement of preformulated lime binder to improve durability of hemp concrete under cyclic wetting/drying aging Considered as a critical factor which contributes to the specimen deterioration, a separate investigation of the degradation rate of the embedded hem...
As the liquid flowrate increases, the ESP experiences a "three-stage" downward trend in pressurization. It is discovered that the first booster stage has a lower inflow velocity and flow separation degree compared to the subsequent booster stages, resulting in a greater liquid-phase pressurization ...
Cyclic shear tests were conducted on these samples to study their shear strength changes with the cyclic number considering the effects of normal stress, joint surface morphology, shear displacement amplitude and shear rate. The results indicate that the shear stress vs. shear displacement curves ...
Respirable suspended particulate matter various sections were measured by SKC Leland Legacy pump on 2.0 μm pore size PTFE (Teflon) filter at flow rate of 9.0 liters/min. The machine was attached to the worker and as such 20 dust samples were collected in four separate areas in the ...

In this research work, the UHPC's service life can be predicted when exposed to different concentrations of sulfuric acid. When comparing acid and sulfate attacks, the latter becomes negligible. Despite the use of silica fume and fly ash, the reactivity with sulfuric acid was found to occur ...
In the present work the propagation phase is generalised to not being only with a constant corrosion rate, but also with the alternatives of presenting non-constant corrosion rates through a sequence of consecutive periods of constant corrosion rate (bi-linear behaviour). The other most frequent ...
