Marston, who played Michael McBain on One Life to Live from 2004 to 2007 after starring as Alonzo Al Holden on that show from 2001 to 2004, was involved in a single-car accident in Reno, Nevada, on October 30.

One cubic yard of concrete weighs around 4,000 pounds. Concrete is measured in cubic yards. Concrete is made out of sand, gravel and cement. Cement is made out of limestone, silica and alumina. Cement is a gray powder that reacts with water to harden the concrete.
Calculating from Volume. This standard concrete mix (used for most premix applications) weighs about 133 pounds per cubic foot of concrete, so a cubic yard (which contains 27 cubic feet) will weigh in at about 3,600 pounds. With the given mix ratio, cured concrete is about 22 percent cement by weight. Thus, a 3,600-pound cubic yard contains about 800 pounds of cement, which comes out to 10 of the 80-pound bags of cement or 13.3 of the 60-pound bags. Pure cement, sand and crushed rock all have about the same density, so a block of pure cement measuring 1 cubic yard of volume (about 3,600 pounds) will contain 45 bags of cement.
