This research is to investigate the effect of borosilicate glass powder on neutron shielding capability of cement mortar. The average particle size of the borosilicate glass powder was 13 μm. It was found that the addition of borosilicate glass powder increased 28 day compressive strength. In addition, neutron shielding capability of cement mortar also increased by the addition of borosilicate glass powder. Considering our earlier findings on enhanced thermal neutron shielding of cement mortar by borosilicate glass powder, the use of borosilicate glass powder was found to be effective to shield neutron when the cement mortar was exposed to the neutron radiation. It can be concluded that borosilicate glass powder is a good alternative material for neutron shielding purposes.
