Each tonne of portland cement produced produces about a tonne of CO2, about half of which is produced when calcium carbonate (limestone) is heated to 1400` and turned into calcium oxide. Mining, processing and transport accounts for the other half.So no, cement is not good for the environment.Geopolymer cement,the type used by the Romans, is a lot more environmentally friendly. When made, It is only heated to 700`, and this produces only a tenth of the CO2.It is the equal of portland cement in strength and longievity,and very fast cure times are possible when needed.It costs around the same to make. The Romans used a naturally occurring geopolymer (accelerant) which is only found in the Bay of Naples, but synthetic geopolymers have been around since the 1970s.Until now, there hasn't been any incentive to switch to this,but hopefully carbon trading will make it viable.Cement production makes up 5% of our carbon emissions(about the same as aviation) and doing this will make a real difference.
Cement production is a significant source of greenhouse gas emissions, mainly due to the chemical process involved in making it. The mining and transportation of raw materials also have environmental impacts. However, efforts are being made to develop more sustainable and environmentally friendly alternatives to traditional cement, such as using recycled materials or incorporating carbon capture technologies.
