    Abstract: This paper focuses on methodological issues relevant to corrosion risk prediction models. A model was developed for the prediction of corrosion rates associated with hot-dip galvanised reinforcement bar material in concrete exposed to carbonation and chlorides in outdoor environment. One-year follow-up experiments, over five years, were conducted at various carbonation depths and chloride contents. The... More

    Abstract: Energy consumed by buildings accounts for approximately one-third of the total energy consumption of the society. Moreover, energy systems employed in buildings emit hazardous pollutants, such as, NOx, PM2.5 and CO2, into the environment. Consequently, increasing the energy efficiency of buildings constitutes an important problem concerning the field of building-energy and environment conservation. Thermal resistance... More

  • Effects of the Addition of Sawdust Ash and Iron Ore Tailings on the Characteristics of Clay Soil

    Abstract: An evaluation of the effects of additives and firing temperatures on clay bricks characteristics was studied. The two (2) additives used were sawdust ash (SDA) and iron ore tailing wastes (IOTW), and the five (5) firing temperatures of 400o C to 1200o C at intervals of 200o C were applied. The fired bricks were tested... More

  • Physio-Chemical Characteristics and Acid-Sulphate Reactions of Moringa Oleifera Seed Powder Cement Paste and Concrete

    Abstract: The evaluation of the effect of using moringa oleifera seed powder (MOSP) to partially replace cement by wt. % has been carried out. A mix parameter of 1: 1.7: 2.5, with designed strength of 20 kN-m2 , and a cement content of 420 kg-m3 , water-cementitious ratio of 0.5, to produce concrete specimens to which... More

  • Photon and Fast Neutron Transmission Parameters of Metakaolin Doped Concrete

    Radiation-shielding properties of metakaolin doped concrete samples were
    investigated in this report. The gamma photon mass attenuation coefficients
    and exposure buildup factor of the samples were determined theoretically
    using WinXcom and EXABCal software respectively for the energy
    range of 15 keV - 15 MeV and fast neutron removal cross section for the
    concrete sample was evaluated. Results indicated that, oxides... More


  • Hemp Concrete: A Sustainable Green Material for Conventional Concrete

    Concrete is one of the most important building material and day by day the
    utilization of concrete is increasing to meet the infrastructure development
    requirement. On one hand it is unavoidable but some alternative to be
    explored to reduce the global environmental impact caused by the concrete.
    To overcome this from the last decade the world is looking towards... More

  • Partial Replacement of Cement by Solid Wastes as New Materials for Green Sustainable Construction Applications

    Abstract: The manufacturing of ordinary Portland cement is an energy-intensive process that results in pollution and CO2 emissions, among other issues. There is a need for an environmentally friendly green concrete substitute. Waste products from a variety of sectors can be recycled and used as a green concrete substitute. This decreases the environmental effects of concrete... More
