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."

Structures That Breathe: India's Move Away from Cooling Machines

India is building homes that stay cool naturally, reducing the need for air conditioners. This helps save energy and costs.

New homes in India are being built to stay cool without air conditioners, using old building methods. This is a big change from using more energy.

🌿 Picture this: you’re standing in your backyard, ready to start that landscaping project.

The right aggregates can make or break your plans!

Here's where you should consider buying: • Local quarries often provide fresh, high-quality materials.

• Builders' merchants typically have a wide selection for all your needs.

Ever thought about how sturdy steps can change your outdoor experience?

Building your own step treads and risers might be just the DIY project you're looking for!

With the right tools like a circular saw and some treated timber, you can create a solid foundation for your staircase.

Think recycled plastic is too flimsy for real construction? Think again!

MIT engineers are flipping the script with 3D-printed beams and trusses made from recycled materials. These innovations create lighter, modular framing that not only cuts down on wood demand but also keeps waste in circulation.

This breakthrough could change the game for how we build and significantly lower carbon emissions in the process.

So, I saw a piece about the #Taos #Earthship community late last night on #VeryLocal (unfortunately, I can't find any video link as yet). However, I did find a piece from 2024 about them...

"This summer’s extreme heat and the demand for air conditioning are putting a big strain on the electricity grid in many parts of the nation. But for more than 40 years, a pioneering architect in New Mexico has been building a unique kind of home that can be heated and cooled without using any electricity at all. Special Correspondent Megan Thompson reports."
