Define solid and hollow masonry units according to ASTM C90.

What are the advantages of masonry walls over framed (wood) walls?

A concrete masonry unit is tested for compressive strength and produces the

following results:

Failure load = 726 kN

Gross area = 0.081 m2

Gross volume = 0.015 m3

Net volume = 0.007 m3

Is the unit categorized as solid or hollow? Why? What is the compressive

strength? Does the compressive strength satisfy the ASTM requirements for

load bearing units shown in Table 8.2?
