So, this fella does a lot of stuff without any precautions! I like the concepts, but if one is going to #DIY making #Lime, working with fire, etc., please use appropriate safety precautions!

"It isn’t just that #Romanconcrete is more lasting. It is also not as bad for the environment in the manufacturing of it because the mix only needed to be heated to 900 Celsius as opposed to the 1,450 of modern concrete.
“Stronger, longer-lasting modern concrete, made with less fuel and less release of carbon into the atmosphere, may be the legacy of a deeper understanding of how the Romans made their incomparable concrete,” Ancient-Origins.net wrote in 2013. Heating the limestone in 19 billion tons of Portland cement made annually accounts for 7 percent of human-released carbon into the atmosphere, according to the new study."
