EUROPEAN PROJECT. C-SHIELD
High-performance cementitious materials with recycled aggregates as neutron shielding for radioactive facilities
The main objective of the C-SHIELD project is to research and develop the use of materials for facilities handling radioactive substances emitting beta, gamma and neutron particles.
About C-SHIELD
Specific objectives and technological applications
The growing demand for greater safety in structures is driving the innovation of new materials. In recent years, high-performance cementitious materials have experienced a rapid increase due to their own superiority over common materials and can easily be used as protection material.
During the C-SHIELD project, TESELA will develop new mixes based on recycled aggregates and ultra-fine high-density powdered materials partially replacing sand. The recycled aggregates will be by-products of the metallurgical industry. The material obtained will be used for incorporation into radiation shielding partitions inside nuclear facilities.
Main benefits derived from the project
To achieve the main objective of the project, UHPC blends will be synthesised and characterised to confirm that they meet several minimum criteria using different techniques (FESEM, EDX, EDS, XRD and mechanical strength).
In addition, neutron tomography (NeXT), neutron reflectometry (D17) and small angle neutron scattering (D33) techniques in imaging mode and attenuation measurement will be used as a ReMade service of ILL (Grenoble, France) to obtain information on the neutron shielding of the created materials.
