Which way is a cinder block strongest? - AskingLot
A concrete block contains stone or sand which makes it heavier. In this way, how much weight can a cinder block hold on its side? The specifications (ASTM C90) for hollow load bearing concrete masonry units require that the block has a net compressive strength of 1900 psi. Since a 8" block is about 50% solid, it would take about 120,000 pounds ...

If used with Type N mortar, any C90 unit can be used for projects having f'm values up to 1,350 psi (9.3 MPa). Conversely, if the concrete masonry units have compressive strengths of 2,800 psi (19.3 MPa), then the maximum f'm used in design would be 2,000 psi (13.8 MPa) if Type M or S mortar were used.
