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-à-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. © 2017 Elsevier LtdConcrete mixersConcrete mixingConcrete mixturesConcretesHigh density polyethylenesNeutron irradiationPolymersSelf compacting concreteShieldingConventional concreteDose transmission factorHigh density polyethylene(HDPE)Hydrogen loadingsNeutron radiationsPolymer-incorporatedShielding characteristicShielding propertiesRadiation shieldingconcretehydrogenpolyethylenepolymer incorporated self compacting concrete mixunclassified drugArticlechemical analysiscontrolled studyneutron radiationneutron radiation shieldingradiation doseradiation energyradiation measurementradiation shieldradioactivityradiological parameterstrend study
