BUILDING STONES

Image
A building stone is obtained from the rocks in the earth- crust. It is considered to the king of engineering materials. And where durability any permanency of a structure are required it continues to enjoy its superiority over all other rival materials of engineering construction. Stones were used in early days for structural works. Important historic examples of the uses of stones are the TajMahal, Buddhist Temple and Kutub Minar in India. The Pyramids of Egypt, the remains of Greecian and Roman structures and many other massive and beautiful structures found practically throughout the world. The main censer of extensive use of stone is that selected properly. It has less wear and tear and does not involve much maintenance cost. Therefore, engineers must have through understanding of the characteristic properties of different types of stones available in their own country to ensure their proper and most beneficial application leading to the successful design and construction of struct...

Bricks

Image
Definition : A brick is an artificial kind of stone made of clay whose chief characteristics are a plasticity when wet and stone like hardness after being heated to hight temperature. Factors that Affect the Quality if Bricks: The following are the factors on which the quality of bricks depends:                           1. Chemical properties of the clay used.                                                                                                                      2. Preparation of the clay.                                    ...

Properties of Engineering Material

Image
A quality that defines a specific characteristic of material is termed as a property. The properties of a material provide a basis for predicting its behavior under various conditions. They are the tools the engineer uses to solve his material problems. Some of the most important properties of engineering material are:                                                                                                                                                                                     1  .       Physical Prop...

General Consideration

Image
  Any material which has got application in engineering   constructions is termed engineering material. In all branches of engineering, and understanding of nature of engineering materials is becoming increasingly vital. Not only are requirements for materials for engineering applications growing more complex, but there are more materials to choose from every day. The engineer can longer be satisfied with a superficial knowledge of a fees standard properties of a few commonly used materials. So many variation in properties are available that the behavior of materials. This understanding can be developed only through a knowledge of properties of materials. A bridge or a dam or a building or a road is to be built, and the choice of materials is up with the engineer, shall steel or concrete be selected, or are there newer materials that might prove superior? The choice must be based on several factors; availability of materials ,economy ease of handling and fabrication, durabilit...
