The density of cement can be anywhere from 62 to 81 pounds per cubic foot, depending on the type of cement. General purpose cement, for example, can have a density up to 81 pounds per cubic foot.Based on data for different phases in these septarian concretions, we suggest that initial body-cement precipitation occurred at relatively shallow depths from unmodified seawater, followed by fringe formation at elevated temperatures that likely coincided with the emplacement of the secondary body phase. ...
