a Why is it important that the concrete masonry units meet certain absorption requirements?

b. A portion of a normal-weight concrete masonry unit was tested for

absorption and moisture content and produced the following masses:

mass of unit as received = 1.95 kg

saturated mass of unit = 2.13 kg

oven-dry mass of unit = 1.91 kg

immersed mass of unit = 0.95 kg

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?
