Toronto to push back on FIFA World Cup's 'greedy' water bottle ban
The forecast for the upcoming FIFA World Cup opener in Toronto between Canada and Bosnia and Herzegovina calls for temperatures up to 30 degrees C, and fans will not be allowed to bring reusable water bottles into the venue.FIFA has informed ticket holders that reusable water bottles will no longer be permitted at any 2026 FIFA World Cup venue due to t...

Making And Using #Lime #Mortars

An article originally written for "Rural Wales" the magasine of CPRW

"The operation of modern #cement and lime mortar is quite different. Cements set by a non-reversible chemical action to form a solid, non yielding mass. #LimeMortars set by the absorption of #CarbonDioxide over a much longer period of time. An understanding of the chemical action of lime is therefore helpful.

"Lime is derived from #limestone or Calcium Carbonate (#CaCO3), which has been burnt in a lime kiln at over 800 degrees centigrade to produce #quicklime or #CalciumOxide (#CaO). In this process carbon dioxide and any water is driven off. Quicklime is potentially dangerous having an avid thirst for water. This process creates a lot of heat and produces #SlakedLime or #CalciumHydroxide (Ca(OH)2). Builders merchants stock this material having been reground to a fine powder and called #HydratedLime.

"The slaking process releases enough heat to cause the water to boil or spit. For this reason water must NEVER be added to quicklime. The lime must ALWAYS be added slowly into the water in a metal container. For the inexperienced builder or home craftsman, slaking is therefore not recommended.

"#HydratedLime can be used as the basis of all lime plasters and mortars. It will slowly absorb free carbon dioxide in the atmosphere and revert to #CalciumCarbonate. A triangle has therefore been completed converting the #calcium back to its original chemical form of limestone. For this reason lime mortars have the potential for #ContinuousRecycling."
