• Reinforced concrete

    Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and is usually embedded passively in the concrete before the concrete ...

  • Types of Building Materials Used in Construction

     · Concrete is a composite material made from mixing cement, aggregates such as sand and crushed stone and water. The properties of concrete depend on the ratios used in the mix design. Therefore, it's a standard practice for concrete suppliers to provide material properties and test results for each concrete patch. Fresh concrete can be poured into form .

    Plane: A plane can be thought of as a line in motion and of having 2 dimensions length and width. In order to create a plane the line moves in a direction that is other than its primary direction. A plane in 2d graphic terms is a shape. It is a surface with length and width that encloses an area. When shapes have 3 dimensions they are called forms. In 2d graphic design forms are .

     · Some types of concrete hold billions of microscopic air cells in every cubic foot. These tiny air pockets relieve the internal pressure on the concrete. They provide tiny chambers where water can expand when it freezes. The air is entrained in the concrete by adding various ing agents such as alcohols, resins or fatty acids during the mixing process. This must be done under careful ...
