Weeraseka, IRA; Rowel, WDNP; Dassanayake, CI; Ratnayake, KC; Wickramaratne, PVL [Conference-Extended-Abstract]

A slab on grade is simply a slab constructed on earth or ground. Often these types of slabs are encountered in the industrial practice. There are several types of slabs on grade commonly used such as pavement slabs found ...
Computer aided hazard analysis for mixing operation: case study of an instant string hopper mixture

Wimalasiri, KYD; Gunasekera, MY [Conference-Abstract]

Rapid industrialization and the severe industrial accidents occurred during the past decades have increased the public awareness on the negative impacts of present technologies used and the hazards posed by potential ...
Cracks in masonry walls due to thermal movements of overlying slab

Dilrukshi, KGS; Dias, WPS [Conference-Extended-Abstract]

Concrete slabs exposed to direct sunlight experiences temperature related horizontal movements. In addition, temperatures on the top surface will be higher than those on the underside of the slab, causing an upward movement ...
Critical analysis of banki turbine

Fernando, MARV [Conference-Abstract]

'Banki turbine', named after its inventor professor Banki, is different from other types in that the flow through the turbine is across it. Thus some literature prefers to call it 'crossflow turbine', while some others ...
