    Effect of waste ceramic tiles as a partial replacement of aggregates in concrete
    (Elsevier Ltd, 2019) Bommisetty, J.; Sai Keertan, T.S.; Ravitheja, A.; Mahendra, K.
    In recent constructions, the consumption of ceramic materials is increasing day by day in the form of tiles, sanitary fittings, electrical insulators etc. But a large quantity of ceramic materials changes into wastage during processing, transporting and fixing due to its brittle nature. Therefore, using these wastes in concrete production could be an effective measure in maintaining the environment and improving the properties of concrete. Hence, the crushed waste ceramic tiles were used in concrete as a replacement for natural coarse aggregates with 0%, 5%, 10%, 15% 20% and 25% of substitution. After analyzing results, the optimum value of waste ceramic tile to be used within the concrete mix with a water/cement ratio of 0.5 was determined as about 20%. The findings revealed that using waste ceramic tile lead to enhancing the properties of concrete. © 2019 Elsevier Ltd. All rights reserved.

    Engineering Properties of Heavyweight Concrete—A Review
    (Springer Science and Business Media Deutschland GmbH info@springer-sbm.com, 2021) Sharath, B.P.; Das, B.B.
    Heavyweight concrete which differs from normal weight concrete by having a higher density and special compositions to improve its attenuation properties, the density and cost of the material are really important in order to absorb gamma rays. If the main aim of developing heavyweight concrete is focussed to attenuate neutrons, then the material with less atomic weight should be embodied in the concrete mix which can in turn produce hydrogen. It is used in counterweights of bascule and lift bridges, but its general application includes in radiation shielding structures, offshore, ballasting of pipelines etc. The evolution of nuclear power into peaceful applications has given rise to an expanding use of heavy weight concrete in construction industries nowadays. Heavyweight concrete employs bulky conventional aggregates such as barites or magnetite or artificial aggregates such as Fe ore or Pb shots. This paper states a review on impact on engineering properties of Heavyweight concrete such as compressive, split tensile and flexural strength with different heavyweight aggregates as per the investigations conducted by researchers. © 2021, Springer Nature Singapore Pte Ltd.
