Clay bricks have been used for construction for thousands of years -- and while some advances have been made, and mechanization has made the process easier and faster, the essential technique for making bricks from clay has remained unchanged. The process requires only a few basic tools and materials, and can be accomplished just about anywhere.

The density of bricks or weight per unit volume depends mostly on the type of clay used and the method of brick molding (soft-mud, Stiff-mud, hard-pressed etc.). In the case of standard bricks, density varies from 1600 kg/cubic meter to 1900 kg/cubic meter. A single brick (19 x 9 x 9 cm) will weigh between 3.2 to 3.5 kg. depending upon its density.

Jul 03, 2019· Clay Bricks. The main ingredient of bricks is clay, a group of surface minerals that arise from the weathering of igneous rocks. By itself, clay is not useless—making bricks of plain clay and drying them in the sun makes a sturdy building "stone." Having some sand in the mix helps keep these bricks from cracking.

Clay bricks Brick is a ceramic material mainly used in construction industry. Its production process involves forming of clay into rectangular blocks of standard size, followed by firing to temperature ranging from 900 - 1200°C1. It is made of clay or shale and when given desired shape is dried and fired into a durable ceramic product.
