   Sammanfattning : The world is facing a major climate threat where carbon dioxide emissions are in focus. At the same time, society requires new buildings and developed infrastructure. Concrete is one of the most common building materials and 30 billion tonnes are produced annually, which corresponds to about 6 percent of the world's carbon dioxide emissions. LÄS MER

   Sammanfattning : Global cement production is continuously increasing from 1990 till 2050 and growing particularly rapidly in developing countries, where it represents a crucial element for infrastructure development and industrialisation. Every tonne of ordinary Portland cement (OPC) produced releases, on average, about 800 kg of CO2 into the atmosphere, or, in total, the overall production of cement represents roughly 7% of all man-made carbon emissions.
