The basic concept of mixing, forming, drying and baking (using a kiln) is almost identical across most types of bricks (with the notable exception being chemically set bricks). Typical modern fired clay brick composition is 50 to 60% by weight sand/silica, 20 to 30% alumina (directly from clay) and 2 to 5% lime.
#0183;#32;Making clay bricks is an extensive process requiring the right clay and tools. Bricks can be sun dried or fired to high temperature using a kiln. The easiest to make are sundried adobe bricks. Whether you use naturallyoccurring clay or buy clay from a distributor, it is always recommendable to test your clay recipe.
Conduct this test using the soil you are going to use to make the weatherproofed mud bricks. If the test determines that your soil needs more clay or sand, obtain that ingredient and mix the appropriate amount into the soil. Keep in mind that in the United States, adobe buildings must be made of 25 to 45 percent clay.
Mix the ground clay soil with water to make a thick malleable paste. Traditionally, clay bricks were molded by hand or with wooden tools. Today, many clay bricks are made in purposebuilt molds. Whichever molding method you use, aim to produce clay bricks of the same size and shape.
The batter for making bricks consists of clay, water, and sand. Successful brickyards had a ready source for each of these ingredients. The exact ratios of each depended on the clay that was used. Some clays contained sand already, therefore they did not require as much to make bricks.
Clay brick making guide. How to make bricks using clay. Brick making business idea is a good source of income especially for areas with many clay deposits.
Such bricks are known as the sandmoulded bricks and they have sharp and straight edges. The lower faces of ground moulded bricks are rough and it is not possible to place frog on such bricks. A frog is a mark of depth about 10 mm to 20 mm which is placed on raw brick during moulding.
Place each brick without sliding it or you will push a little ridge of sand between the bricks. You don''t want any spaces between the bricks. After you place each brick, push it down firmly or give it a rap with a rubber mallet or piece of wood to set it in the sand. Check that all the bricks are level as you proceed.
Clay brick making can be a rewarding experience, particularly if you plan to use your bricks to build a wall, or even a building. But for the novice who has never made bricks, it may take some detailed instructions, as well as information about materials, soils, and baking.
Sand is the majority ingredient in making all bricks. There are many varieties of bricks available. A sand lime brick is made with no water. The chemical hardening process can be sped up using steam. The sand and lime ingredients form into calcium silicate. The sand lime brick was invented in the early 1900s and is commonly used in Germany.

But the scientist formed the bricks within moulds without applying pressure, reducing costs and simplifying the brickmaking process, they say. The researchers add that using waste materials rather than clay or shale conserves resources and maintains
