A fire brick is a special type of brick made using fire clay and has a good resistance against high temperatures which are used in kilns, lining furnaces, fireplaces and fireboxes. These bricks are manufactured in a way similar to that of normal bricks, except during the burning process- Fire bricks are exposed to very high temperatures.

2020年7月31日 · Fire clay :- Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick. The United States Environmental Protection Agency defines fire clay very generally as a “mineral aggregate composed of hydrous silicates of aluminium (Al2O3·2SiO2·2H2O) with or without free silica.” Properties of fire clay :-

Refractory mortar is a specially engineered mixture of sand, calcium aluminate, cement, and fireclay. It is used to lay firebrick in places that are exposed to extremely high temperature. The refractory mortar is utilized only to build fire places and shall not be applied on hot faces.

Table-2: Fire Resistance of Clay Masonry Wall. Single Layer Concrete Walls, Floors and Roofs The fire resistance rating of reinforced and plain concrete walls, floors, and roofs depend on equivalent thickness of the element and can be found out using Table-3. The equivalent thickness of different types of concrete masonry is provided in the ...

2020年7月10日 · Comp strength of fire clay bricks varies from 3.5 N/mm 2 to 48.26 N/mm 2. The water absorption % of fire bricks varies from 4 – 10%. These bricks are generally used in lining furnaces kilns, fire boxes and fireplaces. Principal types. Acid Refractory bricks. Silica bricks: 95 – 97% silica, 1 – 2% lime

Similarly, ASTM standard specify that, brick shall be of clay, shale, fire clay, or mixtures thereof, and burned properly to meet good quality brick requirements. If the bricks are burnt excessively or under burnt, they lose equality of color on the surface and strength.

Example: fire clay is high refractory material. Mechanical Properties of Building Materials Mechanical properties of the materials are find out by applying external forces on them. These are very important properties which are responsible for behavior of a material in its job. The mechanical properties are, Strength; Hardness; Elasticity ...

This cement is then mixed with sand, fire clay, and water in the required ratio, and hence, fire-resistant mortar is formed. Fire clay is a type of ceramic clay having resistivity to extremely high temperatures. For this reason, they are used in fire-resistant linings and mortar in buildings, furnaces, and professional kitchens.

The porotherm clay bricks are easy to use, economical, environmentally friendly, and it can be used for the construction of both non-load bearing walls and load bearing walls. The porotherm bricks are low weight, durable, strong, and possess a satisfactory fire resistance. It can be used with dry mortar which eliminate the need for curing time.

The lead glaze formed is smooth and of better quality. Unlike the other glazing methods, the layer formed in this method does not penetrate into the body of clay product. It can be separated easily from the object surface if required. Fire-clay products, terra-cotta products are glazed by …
