Concrete - Aliapur/Wiki GitHub Wiki

Studies were carried out concerning the opportunity to incorporate granulate obtained from the shredding of end-of-life tyres into cement-based mortars and concretes.

The aim of this incorporation is to both lighten the concrete and increase its performances (increased resistance to cracking and the capacity for deformation of these materials). The tests carried out with the laboratory LMDC in Toulouse and the company Eiffage not only showed a clear improvement in the resistance to cracking in the laboratory, but also on outdoor test slabs.

Adding granulate obtained from ELT provides the concrete with increased durability, and a greater aptitude for absorbing mechanical vibrations, with no implementation difficulties.
