Building Construction Handbook, Eighth Edition

Masonry units † these are an option where it is impractical or

cost-ineffective to use temporary formwork to in-situ concrete.

Exposed brick or blockwork may also be a preferred finish. In

addition to being a structural component, masonry units provide

permanent formwork to reinforced concrete poured into the voids

created by:

* Quetta bonded standard brick units, OR

* Stretcher bonded standard hollow dense concrete blocks.
