Polymer Impregnated Concrete (PIC) is produced by impregnating a hardened concrete with a low-viscosity monomer that is then polymerised in-situ. PIC was developed around 1965 at which institution?
Answer & Solution
Correct answer: B.
1. The unit traces the chronology of polymer concrete research.
2. In 1959, the first experimental polymer concrete structure was built by the USSR's Central Scientific Research Institute.
3. In 1965, Polymer Impregnated Concrete was developed in the United States.
4. The first sample of PIC was produced at Brookhaven National Laboratory, which became the lead agency for PIC research.
5. Bureau of Reclamation suggested it, but Brookhaven produced the first PIC sample.
