Currently, researchers are paying attention to modelling the behaviour of the bond between the concrete ... -
End-of-life solution prioritization for pre-cast concrete components aligning with circular economy targets
Samarakoon, Mudiyansele Samindi Manjula K; RATNAYAKE MUDIYANSELAGE, Chandima (Peer reviewed; Journal article, 2022)Circular economy (CE) targets provide an economic model to focus on the efficient use of resources by minimization of the waste, reduction of the linear consumption of natural resources, long-term value creation, and making ... -
Engineering properties and microstructure of a sustainable roof tile manufactured with waste rice husk ash and ceramic sludge addition
Subashi De Silva, G. H. M. J.; Aagani, T.H.F; Gebremariam, Kidane Fanta; Samarakoon, Mudiyansele Samindi Manjula K (Peer reviewed; Journal article, 2022)Clay replacement with waste rice husk ash (RHA) and ceramic sludge (CS), helps to reduce the consumption of natural clay and solves the ecological issues created by waste disposal. In this study, properties of waste RHA ... -
Experimental investigation of crack width variation along the concrete cover depth in reinforced concrete specimens with ribbed bars and smooth bars
Guruge, Chavin Nilanga Naotunna Palliy; Samarakoon, Mudiyansele Samindi Manjula K; Fosså, Kjell Tore (Peer reviewed; Journal article, 2021)Crack width variation along the concrete cover depth has been studied from the past for better understanding of the cracking phenomenon in reinforced concrete (RC) structures. Previous studies have highlighted important ... -
