PRESTRESSED CONCRETE The development of early cracks in reinforced concrete due to incompatibility in the strains of steel & concrete was perhaps the starting point in the development of new material like “Prestressed Concrete”. Prestressed Concrete is a method for overcoming concrete’s natural weakness in tension. INTRODUCTION Prestressed Concrete is basically concrete in which internal stresses of suitable magnitude & distribution are

multicentered arch An arch having a shape composed of a series of circular arcs with different radii‚ giving an approximation to an ellipse. These arcs are symmetrically disposed about a vertical axis and occur in odd numbers. Construction known as an ‘arch ring’‚ made of truncated wedge-shaped voussoirs that by mutual pressure stay in place‚ set out in a curved form to span an opening and carry a superimposed load. Installation of flashing with other arch types‚ such as segmental and semicircular

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

Foam concrete advantages Foam Concrete is normal concrete with bubbles of air inside. Therefore it has the same characteristics with many additional advantages. CLC (foam concrete) blocks are used for building cottages‚ wall insulation in multistory buildings and internal partitions. Also CLC can be produced and poured for floors and roofs on-site. In roofs it can be used because of very good insulating and lightweight. For floors CLC offers faster installation and a less expensive option because

INTRODUCTION Cement is a binder‚ a substance that sets and hardens independently‚ and can bind other materials together. The word "cement" traces to the Romans‚ who used the term opus caementicium to describe masonry resembling modern concrete that was made from crushed rock with burnt lime as binder. The volcanic ash and pulverized brick additives that were added to the burnt lime to obtain a hydraulic binder were later referred to as cementum‚ cimentum‚ cäment‚ and cement. Cement is made by grinding
