  2. Here’s Why You Shouldn’t Use Salt on Concrete - AOL

    Michigan Concrete Association recommends a regular salt like Morton table salt instead of an ice melter because it’s 100 percent sodium chloride (NaCl). This, however, is recommended for ...

  3. Concrete degradation - Wikipedia

    en.wikipedia.org/wiki/Concrete_degradation

    When atmospheric carbon dioxide (CO 2), or carbonate ions (HCO − 3, CO 2− 3 dissolved in water) diffuse into concrete from its external surface, they react with calcium hydroxide (portlandite, Ca(OH) 2) and the pH of the concrete pore water progressively decreases from 13.5 – 12.5 to 8.5 (pH of water in equilibrium with calcite).

  4. Health effects of salt - Wikipedia

    en.wikipedia.org/wiki/Health_effects_of_salt

    Salt is a mineral composed primarily of sodium chloride (NaCl) and is used in food for both preservation and flavor. Sodium ions are needed in small quantities by most living things, as are chlorine ions. Salt is involved in regulating the water content (fluid balance) of the body. Both sodium and chlorine ions are used for electrical signaling ...

  5. Salt poisoning - Wikipedia

    en.wikipedia.org/wiki/Salt_poisoning

    Salt poisoning is an intoxication resulting from the excessive intake of sodium (usually as sodium chloride) either in solid form or in solution (saline water, including brine, brackish water, or seawater). Salt poisoning sufficient to produce severe symptoms is rare, and lethal salt poisoning is possible but even rarer. The lethal dose of ...

    en.wikipedia.org/wiki/Swimming_pool_sanitation

    An electrically operated water pump is the prime motivator in recirculating the water from the pool. Water is forced through a filter and then returned to the pool. Using a water pump by itself is often not sufficient to completely sanitize a pool. Commercial and public pool pumps usually run 24 hours a day for the entire operating season of ...

  7. Environmental impact of concrete - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    Weathering carbonation occurs in concrete when calcium compounds react with carbon dioxide (CO 2) from the atmosphere and water (H 2 O) in the concrete pores. The reaction is as follows. First, through chemical weathering, CO 2 reacts with water in the concrete pores to form carbonic acid: CO 2 + H 2 O ⇌ H 2 CO 3

  8. Salt water chlorination - Wikipedia

    en.wikipedia.org/wiki/Salt_water_chlorination

    Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...

  9. Saltwater intrusion - Wikipedia

    en.wikipedia.org/wiki/Saltwater_intrusion

    Water extraction drops the level of fresh groundwater, reducing its water pressure and allowing saltwater to flow further inland. Other contributors to saltwater intrusion include navigation channels or agricultural and drainage channels , which provide conduits for saltwater to move inland.
