Additive enhances concrete properties for reduced cement use

摘要

The reduction of greenhouse gas emissions - specifically carbon dioxide (CO_2) - is a worldwide challenge, recorded in the Kyoto Protocol. Carbon dioxide accounts for 80% of the greenhouse gases that are emitted by the industrial countries. The Kyoto Protocol has challenged the world community to try to limit its energy consumption and to replace fossil fuels with renewable and alternative energy. Also a large number of initiatives are starting to reduce CO_2 emissions in different ways.
