  • Determination of Tensile Strain Capacity of Fresh Concrete: A new test method 
    Weerasinghe, TGPL; Nanayakkara, SMA [Conference-Full-text]
    Measuring physical properties of fresh concrete is important to understand the behaviour of the early state of concrete. Plastic shrinkage occurs at the very early stage due to evaporation of water from the concrete surface. ...
  • Early age thermal crack control in mass concrete 
    Girihagama, AWRMGWDB; Nanayakkara, SMA [Conference-Abstract]
    Early age thermal cracking due to temperature differential is one of the major issues related to mass concrete construction. Temperature differential is created due to heat of hydration of cement and heat loss from the ...
  • An Experimental Investigation on Thermal Properties of immature Concrete 
    Mataraarachchi, AIGK; Sayanthan, R; Nanayakkara, SMA [Conference-Full-text]
    Abstract: Since the heat of hydration of cement is highly temperature dependent, variation of thermal properties of concrete at early ages is essential to predict the temperature rise and distribution due to heat of ...
  • Use of waste rubber granules for the production of concrete paving blocks 
    Gamalath, HGP; Weerasinghe, TGPL; Nanayakkara, SMA [Conference-Abstract]
    Worldwide uses of rubber products are increasing every year. A significant proportion of waste rubber is generated during the manufacturing process of rubber products, and the disposal of such waste has been a problem due ...
