Question

A portion of a medium-weight concrete masonry unit was tested for absorption and moisture content and produced the following results:

mass of unit as received = 5435 g
saturated mass of unit = 5776 g
oven-dry mass of unit = 5091 g
immersed mass of unit = 2973 g
Calculate the absorption in kg/m3  and the moisture content of the unit as a percent of total absorption. Does the absorption meet the ASTM C90 requirement for absorption?
