The sad news is this is all carbon intensive ... concrete production is one of the biggest sources of carbon pollution ... cooking limestone at 1,300ºC for two hours just belches the CO2 ... not to mention all the CO2 driven off the limestone to make it cement ... a pound of cement releases a pound of CO2 ...
Limestone sources free of mercury are few and far between ... keeping the mercury vapor from escaping is extremely expensive ... so it's just released into the atmosphere along with the CO2 ... the workaround is not use concrete for our power plants ... use wood framing ... what could possibly go wrong? ...
