    Electrical resistivity of steel fiber reinforced concrete (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-12-16
    Description: Electrical resistivity is one of the key electro-physical characteristics describing the steel fiber reinforced concrete’s ability to conduct electric current. The experiments were carried out to test the hypothesis for the occurrence of a short-circuit effect in steel-fiber concrete structures for the method of electrode heating. Further studies were made to determine the electrical resistivity for various compositions of steel fiber reinforced concrete. The mathematical regularity was found to determine the change of specific electrical resistance subject to the water-cement ratio, the percentage of fiber, the modulus of the fiber surface, and the size of the aggregates. Graphic nomograms (a group of line charts) were made to determine the value of the electrical resistivity for steel fiber reinforced concrete and choose the parameters of electrical heating and the appropriate operating mode of technological equipment.

    Cost Effectiveness of Precast Reinforced Concrete Roof Slabs (2017)
    Institute of Physics (IOP)
    Details
    Publication Date: 2017-11-29
    Description: Engineers always seek to free interior space from intermediate supporting elements. Nowadays plants, being at the forefront of technology, produce a new generation of exclusive patented prefabricated reinforced concrete elements with a high load-bearing capacity, excellent heat resistance characteristics combined with the aesthetics and beauty. It is a system of Seagull Gabbiano prestressed roof slabs for the spans of 12m - 40m. The article shows the advantages of the Seagull slabs over conventional precast reinforced concrete and metal roof trusses. It also gives the analysis of the technical and economic indices of design and construction of a building with the Seagull slabs depending on the size of spans to cover. The use of structural systems with increased spans allows for the modern buildings and structures of prefabricated reinforced concrete with enhanced functionality and aesthetics alongside with a wide range of planning solutions.
