An experimental investigation on strength characteristics of concrete using Wastepaper Sludge Ash (WPSA) (2022)
Conference Proceeding
Umar, T., Tahir, A., Umeokafor, N., Nawarathna, A., Zia, A., & Honnur Vali, M. S. (in press). An experimental investigation on strength characteristics of concrete using Wastepaper Sludge Ash (WPSA).

This study explores an experimental investigation in finding the strength characteristics of the concrete made with the addition of (WPSA) as a cementious material. The WPSA has some sort of pozzolanic properties and is high in silica, magnesium and...

Embodied carbon in commercial office buildings: Lessons learned from Sri Lanka (2021)
Journal Article
Nawarathna, A., Alwan, Z., Gledson, B., & Fernando, N. (2021). Embodied carbon in commercial office buildings: Lessons learned from Sri Lanka. Journal of Building Engineering, 42, Article 102441. https://doi.org/10.1016/j.jobe.2021.102441

Growing concerns over the importance of reducing the embodied carbon (EC) of buildings have led to a greater focus on EC-related research and policymaking. Nevertheless, the Sri Lankan building sector is currently lagging behind on this issue. While... Read More about Embodied carbon in commercial office buildings: Lessons learned from Sri Lanka.

Use of cotton apparel waste as an energy source for biomass boilers: A feasibility study (2021)
Journal Article
Prasanga, W. C., Nawarathna, A., & Rathnasiri, P. (2021). Use of cotton apparel waste as an energy source for biomass boilers: A feasibility study. International Journal of Design and Nature and Ecodynamics, 16(1), 41-51. https://doi.org/10.18280/ijdne.160106

The steady growth of the Sri Lankan apparel manufacturing sector over the last three decades has resulted in generating large amount of solid apparel waste. Currently, it is a massive environmental and financial burden of the sector. As a solution, f...

Embodied carbon as a material selection criterion: Insights from Sri Lankan construction sector (2021)
Journal Article
Nawarathna, A., Siriwardana, M., & Alwan, Z. (2021). Embodied carbon as a material selection criterion: Insights from Sri Lankan construction sector. Sustainability, 13(4), Article 2202. https://doi.org/10.3390/su13042202

The choice of materials is crucial in responding to the increasing embodied carbon (EC) impacts of buildings. Building professionals involved in material selection for construction projects have a vital role to play in this regard. This paper aimed t...
