The cement business is among the a few Principal producers of carbon dioxide, a major greenhouse fuel – another two being Electricity manufacturing and transportation industries. On average, just about every tonne of cement made releases one tonne of CO2 in the atmosphere. Pioneer cement suppliers have claimed to succeed in reduced carbon intensities, with 590 kg of CO2eq for every tonne of cement created.[one hundred thirty five] The emissions are due to combustion and calcination processes,[136] which approximately account for forty% and 60% in the greenhouse gases, respectively.
Ornamental stones for instance quartzite, little river stones or crushed glass are sometimes included into the floor of concrete for the ornamental "exposed combination" end, well-known among landscape designers.
