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

pdf Multi-Level Formwork Load Distribution with Post-Tensioned Slabs By Dr Stephen L Kajewski1 Abstract: Formwork and the associated shoring represent a significant proportion of the costs associated with the construction of multi-level concrete structures. To minimize these costs‚ a limited number of formwork and shoring sets are recycled up the structure as construction progresses‚ eliminating the need for a new set of formwork and shoring with each new slab. When a slab is post-tensioned

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
