Analysis of the effect of wind on façade fire propagation through computational fluid dynamics modelling

Gunarathne, GKUS; Rathnayaka, S; Weerasinghe, TGPL; Nanayakkara, SMA [Conference-Abstract]

Façade fires are one of the most critical and increasingly frequent hazards in buildings. These fires pose a great risk to the building occupants. The Grenfell Tower fire, which happened in 2017, killing 72 people, is ...
Applicability of rcpt for performance-based durability design of reinforced concrete structures

Abeywickrama, HM; Nanayakkara, SMA [Conference-Abstract]

Concrete is an extensively used composite material in the construction industry, known for its heterogeneous nature. In the context of structural service life predictions, the durability of concrete plays a vital role, ...
Design of rigid pavement joint spacing for rural roads.

Karunarathne, AMAN; Mampearachchi, WK; Nanayakkara, SMA [Conference-Abstract]

When it is compared with the flexible pavements, tensile stresses along the pavement layers are more significant in rigid pavements. Shrinkage stresses and thermal stresses are the dominant contributors to develop the ...
Determination of tensile strain capacity of fresh concrete

Weerasinghe, TGPL; Nanayakkara, SMA [Conference-Full-text]

Measuring physical properties of fresh concrete is important to understand the behavior of the early phase of concrete. The measurement of tensile strain capacity of fresh concrete predicts the risk of cracking due to ...
Development of dry plaster mix with manufactured sand

Vipushnan, R; Dasanayaka, DMDT; Nanayakkara, SMA [Conference-Abstract]

Demand for sand has increased at present due to the rapid infrastructure development in the country. As a result of excessive extraction, natural river sand has been depleted in river basins around the country. Shortage ...
Development of fibre reinforced paving block for outdoor sports surfaces

Gannoruwa, GKBM; Muthurathne, SSK; Nanayakkara, SMA [Conference-Abstract]

Synthetic fibre blended fabric offcuts generated from textile industry are considered as waste and currently incinerated in cement kilns. Utilisation of textile waste in development of cement based product was focused ...
Development of iso standard sand from local silica sand deposits for cement testing

Ellegama, EGHDB; Muthurathne, SSK; Nanayakkara, SMA [Conference-Abstract]

ISO standard sand is a siliceous natural sand used in the testing of cement for the SLSI certification process, material approval in construction projects, and material clearance in importing cement. Testing laboratories ...
Investigation of drying shrinkage behaviour of concrete with composite cements

Weerasinghe, NT; Nanayakkara, SMA [Conference-Abstract]

Understanding and investigating the drying shrinkage behaviour of concrete is of paramount importance for maintaining the overall performance and long-term durability of concrete structures. The occurrence of shrinkage-induced ...
Investigation of utilization of manufactured sand in cement mortar

Padmasiri, DLW; Nanayakkara, SMA [Conference-Full-text]

This paper presents results of an experimental investigation carried out to study the influence of particle shape and fines content of crushed rock fines on workability and strength of cement mortar. Different types of ...
Limiting values for temperature differentials to control early age thermal cracking of concrete

Girihagama, AWRMGWDB; Nanayakkara, SMA [Conference-Full-text]

Early age thermal cracking due to temperature differential is one of the major issues related to mass concrete construction. Temperature differential is created due to heat of hydration of cement and heat loss from the ...
Service life prediction under chloride-induced corrosion based on rapid chloride penetration test

Karunaratne, PT; Weerasinghe, TGPL; Nanayakkara, SMA [Conference-Abstract]

Concrete is a highly heterogeneous composite material that is widely used in the construction industry. At present with the development of new constituent materials, the durability of concrete is the key factor in the ...
Simulation of thermal behavior of ground concrete slab exposed to solar radiation

Karunarathne, AMAN; Mampearachchi, WK; Nanayakkara, SMA [Conference-Abstract]

Rate of heat flux from solar radiation, thermal properties of concrete and heat loss from concrete due to convection parameters of surrounding influence the temperature variation of an exposed concrete slab. Literature ...
Suitability of limestone and red sand in Aruwakkalu to produce paving blocks used in class a and class b roads

Pirashanth, K; Prashanthan, R; Guluwita, SP; Nanayakkara, SMA [Conference-Abstract]

Paving blocks are used as a top layer of road structures to replace asphalt. Concrete paving slabs are usually made by mixing materials such as Portland cement or other bonding materials, water and aggregates. Compared ...
