This denarius contained an average 4.5 grams, or 1 â 72 of a Roman pound of silver. It formed the backbone of Roman currency throughout the Roman republic. The denarius began to undergo slow debasement toward the end of the republican period.

Lightweight concrete has a cast density of about 115 pcf. A square foot of 1.5â thick concrete weighs about 18 pounds for normal weight concrete and just under 14.5 pounds for lightweight concrete (a weight savings of less than 4 pounds per square foot). For comparison, 3cm (about 1.25â thick) granite weighs about 17.5 lbs per square foot. For most kitchen and bathroom cabinets, little or no modifications are necessary to bear the weight of 1.5â thick normal weight concrete.
