Is there an increased likelihood of a harmful alkali-silica reaction in concrete exposed to seawater?
There is a mistaken notion that potentially reactive aggregates shouldn't be used in concrete exposed to seawater. This notion is stated twice in ACI 201.2R-01, "Guide to Durable Concrete."1 Section 5.1.1 states that:
"Hadley (1968)[2] described a well-documented case of damage to concrete in service where low-alkali cement was used with alkali-reactive aggregate. It dealt with ...

Salt is vital to health.
Townsend Letter: The Examiner of Alternative Medicine
; Though, today, salt is thought to be harmful to our health, in times past, salt was considered to be the foundation of health and, as such, one of the most valuable commodities on earth. The difference between the harmful salt of today and the healthful salt of yesterday has to do with its mineral

Adverse Effects of Sodium Chloride on Bone in the Aging Human Population Resulting from Habitual Consumption of Typical American Diets1-3
The Journal of Nutrition
; Abstract A typical American diet contains amounts of sodium chloride far above evolutionary norms and potassium far below those norms. It also contains larger amounts of foods that are metabolized to noncarbonic acids than to organic bases. At baseline, in a steady state, diets that contain

Taken With a Grain of Salt
The Washington Post
; What's so special about the "popcorn salt" and "margarita salt" sold in supermarkets? Chemically speaking, absolutely nothing. They're plain old salt: sodium chloride. Physically speaking, they're either finer-grained or coarser- grained than ordinary table salt. And that's all. For margaritas, you

The role of sodium perfluorobutyrate in promoting the antioxidancy of DODPA in synthetic esters
Tribology Transactions
; Differential scanning calorimetry (DSC) and oxidation-corrosion tests were employed to evaluate the inhibition of pentaerythritol ester containing sodium perfluorobutyrate (C^sub 3^F^sub 7^COONa) towards oxidation. The results show that C^sub 3^F^sub 7^COONa enhances antioxidancy of

Dose critical
The Press
; All chemicals are toxic; it is the amount (dose) that is critical. Mark Sadler's logic about sodium fluoride and sodium chloride (August 24) still misses the target. Small and large amounts are poor measures in toxicity. If you drank 10 litres of seawater (contains a small amount of sodium
