The construction industry is one of the major and most active
sectors in Europe. It represents 28% and 7% of employment respectively,
of the industry and of all the European economy. Unfortunately
this industry is also responsible for the depletion of large
amounts of nonrenewable resources and for 30% of carbon dioxide
gas emissions. This is particularly serious in the current context of
climate change caused by carbon dioxide emissions worldwide,
leading to a rise in the sea level [1] and being responsible for a
meltdown in the world economy [2]. In order to achieve a more
sustainable construction industry, the European Union recently
established that in a medium term raw materials consumption
must be reduced by 30% and that waste production in this sector
must be cut down by 40%. The use of renewable resources by the
construction industry will help to achieve a more sustainable consumption
pattern of building materials. Concrete is the most used
material on Earth and it is known for its high compressive strength
