If we want to build a house, one of its vital components is a brick. The existence of a partial brick has been replaced by a brick made from a mixture of sand and cement. Nevertheless, the use of bricks is still quite dominant, considering the people are more desirable because the house made of brick feels cooler. The bricks themselves are made of soil with certain characteristics, so not all the ground is good for making bricks.
Bricks are the most important instrument for building a building in the modern era as it is today. Good for building houses, schools, offices and other buildings. If in the past most people used wood for the walls of their houses, but in this modern era, it seems that the trend is slightly changed to see the difficulty of getting processed wood, in addition to the relatively expensive price. Walaupn actually there are some people who still use it. Buildings that use bricks also look more sturdy and not easily weathered by termites. Perhaps on this basis many people use bricks to erect buildings
the soil is the raw material of brick making poses, where the utility is very profitable for humans because the raw material of the bricks is easily obtained. In terms of brick shape easily arranged or installed for the floor, as well as the wall. The soil has some distinctive properties that when in wet conditions have plastic properties but if in a dry state becomes hard, while when burned becomes strong and solid. In general, people use this land or clay as a raw material for the process of making bricks and pottery. The residual combustion ash contains an active silica-alumina compound which can react with calcium hydroxide at room temperature and the presence of water at a certain level may form stable compounds having binding properties. In addition to water used in the process of binding reaction materials used for brick making, also can facilitate the printing of bricks. Ceramics are compounds containing both metal and non-metallic elements. There are many examples of ceramic materials, ranging from cement to concrete (even rocks), glass, electrical insulators, and permanent magnets. The notion of the ceramic process is a series of treatments systematically resulting in changes in the physical and chemical aspects (hereinafter referred to as the characteristics of the system). Ceramic process, in general can be divided into four stages: Selection of raw materials; Calcination; Forming (printing); Sintering (heating) (Suasmoro, 2005). Bricks are one of the elements of the building in the construction of buildings made of clay plus water with or without other mixtures through several stages of workmanship, such as digging, processing, printing, drying, burning at high temperatures until cooked and discolored, and will hardened like a stone if it cooled down to no longer be destroyed when immersed in water (Ramli, 2007). The process of making bricks through several stages, including excavation of raw materials, materials processing, forming, drying, combustion, cooling, and selection (selection).
