Air-dried bricks, also known as mudbricks, have a history older than fired bricks, and have an additional ingredient of a mechanical binder such as straw. Bricks are laid in courses and numerous patterns known as bonds , collectively known as brickwork , and may be laid in various kinds of mortar to hold the bricks together to make a durable ...
Large bricks on a conveyor belt in a modern European factory setting. A brickworks, also known as a brick factory, is a factory for the manufacturing of bricks, from clay or shale. Usually a brickworks is located on a clay bedrock (the most common material from which bricks are made), often with a quarry for clay on site.
Adobe bricks are traditionally made from sand and clay mixed with water to a plastic consistency, with straw or grass as a binder. [32] [d] The mud is prepared, placed in wooden forms, tamped and leveled, and then turned out of the mold to dry for several days. The bricks are then stood on end to air-cure for a month or more.

Clay body being extruded from a de-airing pug. A pugmill, pug mill, or commonly just pug, is a machine in which clay or other materials are extruded in a plastic state or a similar machine for the trituration of ore. [1] Industrial applications are found in pottery, bricks, cement and some parts of the concrete and asphalt mixing processes. A ...
Mudbrick or mud-brick, also known as unfired brick, is an air-dried brick, made of a mixture of mud (containing loam, clay, sand and water) mixed with a binding material such as rice husks or straw. Mudbricks are known from 9000 BCE. From around 5000–4000 BCE, mudbricks evolved into fired bricks to increase strength and durability.
Clay blocks (sometimes called clay block brick) being laid with an adhesive rather than mortar. Bricks are made in a similar way to mud-bricks except without the fibrous binder such as straw and are fired ("burned" in a brick clamp or kiln) after they have air-dried to permanently harden them. Kiln fired clay bricks are a ceramic material ...

For the production of masonry units the source materials—clay and water—are mixed and formed industrially in a string extrusion process. For special purposes, for example the restoration of listed buildings, hand-formed clinkers are used. During the drying process, the water concentration decreases to approximately 3%.
