Evaluation of the performance of peridotite aggregates for radiation shielding concrete

• Using peridotite rich in crystal water as aggregates of radiation-shielding concrete.
• Performance of peridotite concrete is simulated and compared with ordinary concrete.
• Performance of concrete samples is tested.
• Neutron shielding performance can be significantly enhanced by peridotite aggregates.

Peridotite is a kind of material that is rich in crystal water. In this paper, peridotite is used as fine and coarse aggregates for radiation shielding concrete. The transmission data of different concrete thickness and different energy neutron are calculated using Monte-Carlo method. The neutron shielding performance of the peridotite concrete samples are tested using 241Am-Be neutron source. The results show that the peridotite is an excellent neutron shielding material.
