Premium Concrete Tensile strength
Prestressed concrete construction Prestressed concrete Prestressed concrete is a method for overcoming concrete’s natural weakness in tension. It can be used to produce beams‚ floors or bridges with a longer span than is practical with ordinary reinforced concrete. Prestressing tendons (generally of high tensile steel cable or rods) are used to provide a clamping load which produces a compressive stress that balances the tensile stress that the concrete compression member would otherwise

Consolidation of plastic concrete is termed as compaction. In the process of compaction‚ efforts are only directed to reduce the voids in the compacted concrete. Compaction of concrete can be done either manually or mechanically. When it is done manually it is called hand compaction or tamping‚ and in second case it is termed as machine compaction. Hand compaction: Hand compaction is done with the help of steel tamping rods‚ or timber screeds. Marrow and deep members are compacted with tamping

Shrinkage in concrete or mortar depends on a number of factors • Cement concrete: Richer the mix greater is the drying shrinkage. • Water content: More water in mix induces greater shrinkage • Aggregates : Large aggregates with good grading has less shrinkage for same workability as less water

The greatness of Roman architecture is built‚ quite literally‚ upon the foundation of two important items: the discovery of concrete and the adoption of the arch from the Greeks. Concrete was an exceptional development within the Roman world and catapulted Roman construction into new heights of efficiency and stability. According to Kamm (1995)‚ the origin of Roman concrete can be found in a volcanic earth known as pozzolana‚ initially found near the Greek settlement of Puteoli. It would later be
