Bearing Reinforcement Experience of Application of Increased Rigidity in Monolithic Lightweight Concrete Slabs

Implementation of projects using advanced structural and technological designs of erection of buildings implying use of the technology of prestressing reinforced concrete allows overcoming the main drawbacks of monolithic construction: high prime cost, labour intensity and duration of construction and installation operations. The article describes the experience of erecting lightweight concrete monolithic slabs with the use of reinforcing bars of increased rigidity. As a result, a reduction in costs of 25 ... 30%, compared with the floors of heavy concrete without pre-stressed reinforcement is reached.
