Earth matters

Concrete releases CO2 into the atmosphere as it cures (for up to a hundred years). That is another material we need to look into alternatives for.
Even the top scientists miss that sometimes. It took a builder to point out to NASA why the CO2 levels in Biosphere 2 were much higher than predicted.

Yes. The mining of calcium carbonate for cement should be treated as fossil fuels if you are concerned about CO2. The cool thing is that the process of making calcium carbonate out of lime, water and CO2 isn’t that complicated. It is an area where recycling could be encouraged. Making cement carbon neutral is realistic. It would cost more but the market is probably there.

These fucking liberals, man. How in the fuck did we get blamed for their last big idea anyway? They used to freak out over paper bags. We are fucking up the environment because we keep using those paper bags from the grocery store. We needed to choose plastic bags. The grocery stores for a while gave you the option, and if you chose paper, the liberals would virtue signal about how horrible you are for destroying the forests instead of just choosing plastic.

Now these fuckers are saying it's our fault the environment is getting fucked up by plastic bags. Come again? Whose brilliant idea was it to switch from paper to plastic??

[Hastur]

You can’t win. Panic monkeys are gonna panic like monkeys . Virtue signalers are gonna virtue signal. Just hand over your cash.

We've had a better alternative to cement in most usages for centuries.

Lime mortar, render and plaster

Advantages over cement


• By being produced at lower temperatures than cement, lime mortar requires less energy, resulting in 20% less CO2 output.

• Lime putty absorbs CO2 in the curing process. Non-hydraulic lime absorbs nearly its own weight in CO2, hydraulic lime, around 75% and lower.

• Lime mortar can be re-cycled, unlike cement

• Bricks using lime mortar can be recycled unlike the cement bonded equivalent which can only be used for hardcore.

• Strong, flexible, permeable. Traditional buildings built using lime mortar move and absorb moisture. In comparison with cement mortar which is rigid, lime mortar 'moves' with the structure and so prevents masonry from cracking. By using lime mortar, expansion joints can be avoided. Likewise the imperviousness of cement mortar prevents it from absorbing water from the structure whereas lime mortar acts as a kind of 'wick', absorbing the moisture and allowing it to evaporate. By absorbing moisture, lime mortar is keeping the masonry dryer and lessening the risk of spalling.
2 types of lime mortar: Hydraulic and Non-Hydraulic.

Mortar and pointing in brickwork

Non-hydraulic lime mortar ('fat lime') mixed with sand in a 1:3 ratio. However, note that non-hydraulic lime takes time to set. If quick construction is required use hydraulic mortar or non-hydraulic mortar with pozzolan added to speed up carbonation ('lean lime'). Pozzolan is typically brickdust, calcinced clay etc. Adding pozzolan is known as ' gauging'.

Render

Use either hydraulic lime or non-hydraulic. Non-hydraulic lime requires an element of cement. ( Green note: the CO2 equation here involves the balancing of the CO2 produced in the cement making process against non-hydraulic limes greater CO2 absorption than hydraulic lime.) Hydraulic lime will set much faster than non-hydraulic.

Plaster

Un-gauged non-hydraulic lime mortar using well-matured lime putty and sharp and well-graded aggregate. This does not require special skills. Use non-hydraulic lime and sand in a 1:3 ratio. Coat with limewash.

The difference between hydraulic and non-hydraulic limes is that non-hydraulic mortar sets with exposure to the air as it absorbs CO2. Hydraulic lime however relies on a complex chemical reaction between the calcium hydroxide and the impurties which is initiated by contact with water

Wash. Rinse. Repeat.

In fifteen years you fuckers will be blaming us for fucking up the environment with our plaster and blaming us for not using concrete.

In my experience single use plastics bags were strong enough to transport groceries, but were ultimately reused as trash bags. And from my observations, the new bags arent getting much reuse, aside from also being used as trash bags. The drawer of flimsy bags at home has been replaced with a drawer of mega bags. I've never seen someone walk in to a grocery store with them. And when driving through the city, the mega bags have replaced the flimsy bags as litter.

Well, that's not the case here. There's been an 86% reduction in the numbers of bags used and most people seem to reuse them. I keep mine in the car rather than a kitchen drawer so I don't keep forgetting to take them with me.

So how much Sami blood she got? It would explain the eye shape and skin tone. I'm wondering how much of it is alcohol fetal syndrome though.

I don't want the foundation of my house built with something that absorbs moisture or 'moves' with the structure.

WTF are you driving a car for, you wasteful heathen? Walk to the store. If you live too far away from one then you need to move closer to one or live completely off the land.
