Your Guide to Concrete Brick & Blockmaking
The small-scale manufacture of concrete bricks and blocks for masonry is well suited to small businesses. Production can be done in the open, the process is simple and equipment relatively inexpensive.
The aim of this publication is to provide the information needed to set up and run a blockyard to manufacture concrete bricks and blocks on a small scale.
Aspects dealt with include: selecting and establishing a site, selection of equipment, materials for blockmaking, trial mixes and production.
Bricks and blocks are masonry units and are referred to as such in SABS standards. Units may be solid or hollow. The difference between bricks and blocks is size. In this brochure “block” is used throughout, but the same principles apply to brick.
Selecting a site
In selecting a site, consider location, access, ground slope and size. These are discussed below.
This should be considered in relation to:
- Supply of raw materials
- Market for blocks
- Location of the labour force
- Availability of services (i.e. roads, water, sewage, electricity etc).
The site must be accessible to trucks delivering materials and collecting finished blocks.
