This article presents an analytical investigation of the mobility of salts from contaminated aggregates in concrete. Salt-contaminated aggregates may have varied effects on the mechanical properties and durability of concrete. These depend primarily on the mobility of salts within the concrete matrix. Existing diffusion-based models for the mobility of salts in concrete focus on their intrusion from external sources (e.g., chloride penetration from deicing salts and brines). Such problems are well described by the closed-form solution of Fick’s law for diffusion in one dimension from a continuous source. Salt-contaminated aggregates represent a case of diffusion from a finite internal source …

The City of London has a mandate to provide its residents with high grade water and yet there have been complaints concerning the impurities, otherwise known as residuals, and the overall quality. This paper delves into the truth about the contents of the municipal water system and what the effects of its components are to the London populace. A public survey asked residents questions about their concerns and water drinking habits. The survey pointed to concerns about fluoride, residual chlorine and overall taste of water among others. Fluoride is known to reduce tooth decay (CDC, 2018) and any negative consequences …
