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."

Dear Friends from all #universes, 🦞
We had a long #stroll along the #River #Wandle near #Tooting. We stopped off to check out some #pestle and #mortars for grinding #spices. Also, to buy some #mint #plants and #sage. The #tangerine sage should be fun. It has red flowers. I wonder if it is a communist? The sage is #variegated. The mints are #chocolate #peppermint and another #vigerous grower.
Loads of #butterflies on our #traversing and very pleased to see a #newt (also available as a character). 😮
Also did some #sunbathing in the #morning. Will be #planting my new plants #tomorrow #inshallah (which means COD willing). 🦋
Was #delighted to see the new #Food bus, which as part of #ground #roots #UBI gives free food, to the subjects of Princess Charley (also available as a fragrance). :ablobcatpopcorn:
#Nature can't live without it, and #living without it is a c#nt. You knew that, right? Most people seem to. 🕊️
Welcome to #May (not Theresa) and her #warmth. ❤️ -
The Lithuanian Armed Forces have received the first batch of Spanish-made 120mm #mortars. The #Defence Ministry said that the mortars provided a significant improvement to #Lithuania's indirect fire support capabilities.

Russian forces are using low-quality shells sourced from North Korea that are often defective, at times causing damage to the barrels of cannons & mortars & even injuring soldiers
Russian troops have been complaining about the North Korean shells, saying that some show evidence of crucial parts being cannibalized, as well as a general emphasis on quantity over quality
