Development of thermally comfortable paving block arrangement for pedestrian walkways

Hettiarachchi, HACK; Mampearachchi, WK [Conference-Abstract]

Interlocking concrete block pavements are used to pave walkways, parking lots, roadside pavements, open spaces, religious places etc. where people used to walk. The pavements are subjected to heavy thermal loads during day ...
Effect of surface texture, size ratio and large particle volume fraction on packing density of binary spherical mixtures

Hettiarachchi, HACK; Mampearachchi, WK [Article-Full-text]

The packing density of a particulate mixture is an important aspect of materials sciences and engineering. The packing density of a mixture depends on several parameters. This study considers the combined effect of vibration ...
Modified 3 parameter model incorporating particle shape, texture and vibration to predict packing density of binary particulate mixtures

Hettiarachchi, HACK; Mampearachchi, WK [Conference-Abstract]

Particle packing density is one of the most important parameters in materials engineering. Ultra-high-performance concrete (UHPC), lightweight concrete, porous concrete, advanced ceramic materials, porous asphalt, filter ...
Sustainable concrete mix design for interlocking concrete block pavers (ICBP)

Hettiarachchi, HACK; Mampearachchi, WK [Conference-Abstract]

Heavy usage of cement in modern construction industry has led to numerous environmental problems. The cement industry is one of the main industries which release carbon dioxide, a major greenhouse gas. Raw material extraction ...
Validity of aggregate packing models in mixture design of interlocking concrete block pavers (ICBP)

Hettiarachchi, HACK; Mampearachchi, WK [Article-Full-text]

Interlocking concrete block pavers (ICBP) are manufactured using a semi dry concrete mix and vibration and compression are applied by electrical or hydraulic machines to cast the blocks. Hence the concrete mixture ...
