Lightweight ceiling system made of carbon reinforced concrete

Research output: Contribution to journalResearch articleContributedpeer-review


At the Institute of Concrete Structures, Technische Universität Dresden, a new precast ceiling system comprised of an arch and a beam at each longitudinal edge was investigated. The innovative composite material carbon reinforced concrete allows thereby a fresh way of thinking for civil engineering with lightweight constructions but still high bearing capacity. This variation of a beam has only straight rebars as main reinforcement. Four prototypes with a length of 4.50 m were produced and tested at Otto–Mohr-Laboratory of TU Dresden. Except of the supports, the structure has a thickness between 40 and 45 mm, so a reduction of the dead load up to 70.0% compared to a usual rectangular cross section made of common steel reinforcement and the same concrete could be achieved. The experimental ultimate loads of the first three tested elements were thereby higher than the calculated ultimate load of the common reinforced concrete structure.
