  • Finite element analysis of lightweight composite sandwich panels exposed to fire 
    Upasiri, IR; Konthesigha, KMC; Nanayakkara, SMA; Poologanathan, K; Gatheeshgar, P; Nuwanthika, D [Article-Full-text]
    Composite Sandwich Panels (CSP) are a novel type of wall panels, which has gained immense attraction in the construction industry due to its better mechanical performance with lighter weight. Finite Element Model (FEM) was ...
  • Fire performance of cold, warm and hybrid LSF wall panels using numerical studies 
    Perera, D; Poologanathan, K; Gillie, M; Gatheeshgar, P; Sherlock, P; Nanayakkara, SMA; Konthesingha, KMC [Article-Full-text]
    Robust and pre-fabrication construction techniques are the cutting edge practice in the building industry. Cold-frame, warm-frame and hybrid-frame are three common Light-gauge Steel Frame (LSF) wall constructions applied ...
  • Fire performance of lightweight concrete-filled LSF wall panels 
    Upasiri, I.R.; Konthesigha, K.M.C.; Nanayakkara, SMA; Poologanathan, K.; Gatheeshgar, P.; Perera, D. [Article-Full-text]
    Light Gauge Steel Frame (LSF) wall panels with cold-formed thin-walled steel-Lipped Channel Sections (LCS) and plasterboard linings are increasingly used in the construction industry due to their lightweight and constructability ...
  • Metamorphic rocks for manufactured sand and coarse aggregate for concrete and mortar 
    Arulmolya, B; Konthesinghaa, KMC; Nanayakkara, SMA; H.M.R. Premasiriс, HMR [Article-Full-text]
    The present study determined the most applicable high-grade metamorphic rocks as the sources for manufactured sand and coarse aggregates production to apply in the construction industry. As the first stage of this study, ...
  • Offshore sand for reinforced concrete 
    Dias, WPS; Seneviratne, GAPSN; Nanayakkara, SMA [Article-Full-text]
    A figure of 0.075% by weight of sand was arrived at as a safe limit for allowable Cl ion content in offshore sand for OPC based reinforced concrete. A 2 m high sand column was fabricated for checking the effects of natural ...
  • Performance of concrete mixes with OPC-PFA blends 
    Dias, WPA; Nanayakkara, SMA; Ekneligoda, TC [Article-Full-text]
    This paper describes a comprehensive programme of testing for strength, durability (sorptivity, carbonation, drying shrinkage, sulphate attack and chloride ingress) and fresh-state properties (slump, slump loss, setting ...
