AB  - In this work, the neutron radiation shielding characteristics of a class of novel 
      polymer-incorporated self-compacting concrete (PISCC) mixes are evaluated. 
      Pulverized high density polyethylene (HDPE) material was used, at three different 
      reference volumes, as a partial replacement to river sand in conventional 
      concrete mixes. By such partial replacement of sand with polymer, additional 
      hydrogen contents are incorporated in these concrete mixes and their effect on 
      the neutron radiation shielding properties are studied. It has been observed from 
      the initial set of experiments that there is a definite trend of reductions in 
      the neutron flux and dose transmission factor values in these PISCC mixes 
      vis-a-vis ordinary concrete mix. Also, the fact that quite similar enhanced 
      shielding results are recorded even when reprocessed HDPE material is used in 
      lieu of the virgin HDPE attracts further attention.
