A laboratory experiment on salt weathering by humidity change: salt damage induced by deliquescence and hydration

“Salt Weathering” Distress on Concrete by Sulfates?

Laboratory simulation showing the influence of salt efflorescence on the weathering of composite building materials

A common decay scenario in old and new buildings was simulated: the effects on masonry structures of salt efflorescence or subefflorescence produced by the rise of saline solution. Eight different types of masonry wall each made up of a combination of different construction materials (brick, calcarenite and four types of mortar were combined as follows: pure lime mortar, mortar + air entraining...

Comparison between Salt crystallization weathering test and natural weathering in Mesozoic’s anisotropic rocks, a case study: Arakʾs Calcareous slates, Iran

Salt crystallization can severely damage anisotropic foliated rocks, therefore it is necessary to have an understanding of crystallization process. The present study was conducted to investigate the effect of salt crystallization on Arakʾs calcareous slates, as anisotropic rocks of Mesozoic. To compare salt crystallization weathering (EN 12370 norm was used up to 30 cycles) with natural weather...

Fluid, ionic and hormonal changes induced by high salt intake in salt-sensitive and salt-resistant hypertensive patients.

1. The aim of the study was to detect differences between salt-sensitive and salt-resistant hypertensive patients in the response of the renin-aldosterone axis, plasma noradrenaline and atrial natriuretic peptide to high salt intake. 2. Fifty essential hypertensive patients followed 2 weeks of a standard diet with 20 mmol of NaCl daily, supplemented by placebo tablets for the first 7 days and b...
