Title: On Properties of Magnetite and Serpentine Concrete at Elevated Temperatures for Nuclear Reactor Shielding
Author(s): S. Ohgishi, S. Miyasaka, and J. Chida
Publication: Special Publication
Appears on pages(s): 1243-1256
Keywords: compressive strength; concrete; density (mass/volume); heavyweight aggregates; heavyweight concretes; high temperature; magnetite; modulus of elasticity; mortars (material); nuclear reactor containment; nuclear reactors; ophicalcite; radiation shielding
Abstract:A general rule for nuclear reactor biological shielding materials is that an ordinary concrete or high-density concrete using an aggregate such as magnnetite, limonite, etc., is the most reasonable for a thermal neutron reactor. . .This paper consists of two parts: first, an experiment on magnetite aggregate concrete and ordinary concrete at elevated temperatures from 20 C to 600 C is reported, and second an experiment on serpentine aggregate concrete and ophicalcite aggregate concrete subjected to different degrees of heating is reported.
