A study by the Research Centre of the Belgian Cement Industry has shown that the leaching behaviour of classic Belgian road concrete is totally harmless to the environment. The leached quantities of heavy metals are smaller than the quantities found in commercial mineral drinking water.
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;
Use of low energy cements;
Lower fuel consumption for heavy trucks;
Reduced lighting costs and urban heat island effect.
