Abstract

The impregnation by resins of concrete structures is widely known as PIC (Polymer Impregnated Concrete). This process is normally used to improve the physical-chemical features of prefabricated items, in particular to raise their lifetime under severe environmental conditions. The main target of this research was the verification of the possibility of a proper impregnation of existing concrete surfaces, of any dimensions and position, by comparing the obtained characteristics with those of untreated original material to check the improvement of chemical-physical properties and durability. The operative steps of the research were the design, manufacturing and implementation of a purpose-built prototype, the setting-up of the machine, the design and erection of a walling unit made of different density sectors in nuclear grade concrete and optimisation of the PIC process phase (dehydration, degassing, monomer injection, thermal cycles) during the experimental campaign.
