Main components of the modern bridges are: Abutment – Endpoints of the bridge. They are reinforced so that they can endure intense lateral pressures. Pile (also known as beam, footing, and pier) – Reinforced concrete post that is driven into the ground to serve as the leg or support for the bridge. The distance between piles is calculated so that is can support the rest of the structure that will be laid on top of them.

Technical Notebook CEMENT ADDITIVES FOR VERTICAL MILLS 04 2. VERTICAL MILLS - INTRODUCTION Thanks to the necessity to improve grinding efficiency and reduce operation costs, vertical mills have made their way into the cement industry. At first these new systems were employed for the grinding of solid combustibles and kiln-feeding raw meal.
Apr 25, 2012· · Coarse aggregate makes solid and hard mass of concrete with cement and sand. · It increases the crushing strength of concrete. · It reduces the cost of concrete, since it occupies major volume. Requirements: Coarse aggregate used may be crushed stone, gravel and broken bricks.
Applications of cement. Concrete is a mixture of cement, sand or other fine aggregate, and a coarse aggregate that for most purposes is up to 19 to 25 mm ( 3/4 to 1 inch) in size, but the coarse aggregate may also be as large as 150 mm (6 inches) when concrete is placed in large masses such as dams.
