Abstract:For the construction of the counterweights of the bascule span of the Arlington Memorial Bridge, Washington, D.C., it was necessary to design a concrete having a weight of 271 lb per cu ft, not less than 6 bags of cement per cu yd and a compressive strength of at least 2000 psi. Tests indicated that Swedish iron ore combined with steel punchings gave the most satisfactory and economical heavy aggregate. The tests indicated. that from a knowledge of the specific gravity of Ingredients used it is possible to compute the weight of fresh concrete to within about I percent.
