Investigation into the Causes of the Deflexion of Heated Concrete Floors, including Shrinkage

The paper describes large deflexions found in electrically floor heated reinforced concrete slabs in a considerable number of Scottish flats and gives the basic reasons why such deflexions occur. It goes on to describe a number of laboratory tests to ascertain the shrinkage of the aggregates used for constructing the floors and the influence on concrete made with such aggregates and similar sands. The results of E tests are given. An investigation into the temperature and deflexion characteristics with or without live load of a typical flat is described and the results are given, together with examples of deflexion readings from other flats and core crushing results.
