Editing Lithium hydroxide (section)

===Other uses===
It is also used in [[ceramic]]s and some [[Portland cement]] formulations, where it is also used to suppress ASR ([[alkali–silica reaction|concrete cancer]]).<ref>{{cite journal|vauthors= Kawamura M, Fuwa H|year=2003|title=Effects of lithium salts on ASR gel composition and expansion of mortars|url=https://www.osti.gov/biblio/20658311|journal=Cement and Concrete Research|volume=33 |issue=6 |pages=913–919 |doi=10.1016/S0008-8846(02)01092-X |osti=20658311 |access-date=2022-10-17|url-access=subscription}}</ref> 

Lithium hydroxide ([[isotope separation|isotopically enriched]] in [[isotopes of lithium|lithium-7]]) is used to alkalize the reactor coolant in [[pressurized water reactor]]s for corrosion control.<ref>[http://www.gao.gov/products/GAO-13-716 Managing Critical Isotopes: Stewardship of Lithium-7 Is Needed to Ensure a Stable Supply, GAO-13-716] // [[Government Accountability Office|U.S. Government Accountability Office]], 19 September 2013; [http://www.gao.gov/assets/660/657964.pdf pdf]</ref>
It is good radiation protection against free neutrons.
