Abstract:Discusses crushing and handling of the magnetite iron ore, which was used as the aggregate for a dense shielding concrete, and the physical properties and costs of magnetite ore concrete are compared to those of other concretes. The mix used had a compressive strength of 4000 psi in 10 days. The methods used in fabricating shielding block are described. Recommendations for pro-ducing a low cost, relatively high density shielding concrete are made. T h e shielding block used (9 x 9 x 18 in. nominal) had a density of 3.7 g per sq cm or 230 lb per cu ft and cost $163.50 per cu yd. The dimensions of the block were quite uniform, having a standard deviation of approximately 0.015 in.
