The first hollow concrete block was designed in 1890 by Harmon S. Palmer in the United States. After 10 years of experimenting, Palmer patented the design in 1900. Palmer's blocks were 20.3 cm (8 in) by 25.4 cm (10 in) by 76.2 cm (30 in), and they were so heavy they had to be lifted into place with a

6.9.2 Hollow concrete blocks shall be embedded with a mortar which is relatively weaker than the mix used for making blocks in order to avoid the formation of cracks. A rich or strong mortar tends to make a wall too rigid thus localizing the effects of minor movements due to temperature and moisture variations resulting in cracking of the blocks

Concrete blocks are often made of 1:3:6 concrete with a maximum size aggregate of 10mm or a cement-sand mixture with a ratio of 1:7, 1:8 or 1:9. These mixtures, if properly cured, give concrete blocks a compression strength well above what is required in a one-storey building. The blocks may be solid, cellular or hollow
