Mostly portland-fly ash cement (CEM II) or blast furnace slag cement (CEM III/A) is used for road pavements, which means that industrial by-products replace a great part of the clinker. Consequently fewer energy and fossil fuels are needed. In addition, cement industries all over the world make great efforts in reducing their energy consumption by using waste materials as alternative fuel thus contributing to lower overall CO2 emissions and by respecting environmental legislations.
Other cement and concrete's credentials concern:
Durability and longevity, constituting a cost-effective and environmental advantage;
Safe and comfortable surfaces;
Techniques of soil treatment and land remediation;
Recyclability of concrete;
Lower fuel consumption for heavy trucks;
Reduced lighting costs and urban heat island effect;
No danger of leaching.
