More sustainable mortars and concrete with optimal thermal and mechanical efficiency

The consumption of raw materials has increased notably in industry in general, and in the construction industry in particular, amidst growing concerns over sustainability issues. Concrete and mortar are the most commonly used materials in construction, and many studies are currently under way to try and reduce the harmful effects of their manufacture. Concrete and mortar are made by mixing water, sand, cement and aggregates.
The main problem is the amount of cement used to produce this type of material; cement manufacturing uses a huge amount of energy and natural resources, which implies a high level of CO2 emissions. Diverse studies are under way aimed at reducing the quantity of cement required. We are working to replace cement and aggregates (sand or gravel) with non-natural materials, in order to reduce the use of natural resources and optimise the mechanical and thermal properties of the materials produced, explains Roque Borinaga Treviño, a researc ....

The countries around the Baltic Sea do not respect their binding international agreement to reduce agricultural pollution of the marine environment. Despite farming activities being the single most important source of nutrient pollution to the Baltic Sea.
An international research team presents evidence on these circumstances in a recent scientific article in the journal
Ambio, published by the Royal Swedish Academy of Sciences.
The countries made a commitment 20 years ago to implement 10 specific reduction measures in their national legislation on agricultural pollution - e.g. featuring minimum storage capacity for manure and regulations on animal densities. ....
