Ranking of walling materials using eco-efficiency for tropical climatic conditions: a survey-based approach

Gurupatham, SV; Jayasinghe, C; Perera, P [Conference-Abstract]

Construction is an important sector that consumes a significant amount of resources worldwide and produces a lot of waste. Buildings as a whole share nearly a quarter of total electricity generation in tropical countries, ...
Rapidly deployable structures for the tourism industry in Sri Lanka

Mustapha, MSN; Lewangamage, CS; Thompson, LM [Conference-Full-text]

This research involves the concept of creating rapidly deployable ecofriendly cabanas for the tourism industry in Sri Lanka. The cabanas are to be pre-fabricated; thus could be purchased off the shelf and assembled at ...
Reuse of construction waste as coarse aggregate in concrete

Herath, HMUI; Nanayakkara, DN [Conference-Full-text]

The recycling of construction waste as concrete aggregates is an important way to contribute to sustainable development. However, the use of recycled concrete aggregate (RCA) instead of natural aggregate influences the ...
River discharge – water level relationship at wide floodplains

Herath, HMJH; Herath, TMN [Conference-Abstract]

The relationship of the river discharge and water level of a river flow can be explained by Manning’s equation. However, in case of a flood situation, when overbank flow occurs, the flow cross-section related to the flow ...
Roadsideslope risk assessment in Sri Lanka

Gangani, VGD; Kulathilaka, SAS [Conference-Abstract]

Sri Lanka is experiencing frequent events of slope failures, cutting failures and landslides along the road network throughout the island. Considerably high number of events occurred recently, with the growth in the road ...
Seasonal freshwater outflow variation of gin and Nilwala river basins

Dilrukshi, YDNM; Wijayaratna, TMN [Conference-Abstract]

River discharge is primarily related to water resource management because it is an important event in the global water cycle. The hydrological processes within a catchment are influenced by land usage, land cover, soil ...
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 ...
Shear strength characteristics of unsaturated residual soils

Ganeshalingam, C; Kulathilaka, SAS [Conference-Full-text]

The tropical climate conditions cause the residual soils near ground water level to be in an unsaturated state generally. Matric suction enhance the shear strength of the soil. In tropical countries like Sri Lanka where ...
Soil contamination by direct disposal of reverse osmosis reject water onto the ground in the Chronic Kidney Disease of unknown etiology (CKDu) prevalent areas

Jayathilaka, PAVG; Gunawardana, WB [Conference-Full-text]

Reverse Osmosis (RO) units have been installed in areas where Chronic Kidney Disease of unknown etiology (CKDu) prevails to provide good quality drinking water. At present, RO reject water is directly discharged onto the ...
Structural analysis of ancient stupa in Sri Lanka

Premarathne, SGIM; Mallikarachchi, HMYC [Conference-Abstract]

Ancient stupas in Sri Lanka hold immense historical, archaeological, and religious significance. These monumental structures, dating back to ancient times, serve as tangible links to the country's rich cultural heritage. ...
Study of permeability characteristics of open graded friction courses used in wearing courses

Umasangar, K; Mampearachchi, WK [Conference-Full-text]

Open graded friction course (OGFC) has been used by several countries since 1950. While many countries report good performance, some countries have stopped using OGFC due to unacceptable performance and/or lack of adequate ...
Study of the impact to the traffic flow on arterial roads in Colombo due to close distance access roads

Kaumal, THMM; De Silva, D [Conference-Abstract]

The rapid development of Colombo city has resulted in growth in urban traffic. The arterial roads that provide accessibility to Colombo city are experiencing traffic congestions, especially during peak times. The vehicles ...
Study of the influence of construction sequence on slope rectification projects

Kulathilaka, SAS; Vimukthi, HPJ [Conference-Abstract]

Rain–induced slope failures in residual soil slopes are a common geotechnical hazard in most tropical countries like Sri Lanka. To reduce the risk of failure in slopes with low safety margins, or to rectify the slopes ...
Study of torsional buckling behavior of carbon nanotubes using molecular dynamics simulations

Dodangoda, MT; Dilrukshi, KGS [Conference-Full-text]

An accurate study of mechanical behavior of CNTs is vital to understand their response under mechanical loading in their applications. Much experimental and analytical work has been done to quantify the mechanical ...
A study on axial performance of helical piles on residual soils

Liyanage, CN; De Silva, LIN [Conference-Abstract]

Denser/harder soil layers often found under very shallow depths in Sri Lanka. In such circumstances, helical piles offer an economical alternative to traditional foundation types such as pad footings, rafts or piles while ...
Study on buildings suitable to be constructed in hot, windy coastal regions

Dissanayake, DWTS; Baskaran, K [Conference-Abstract]

As Sri Lanka is a small island located in the Indian Ocean close to the equator, most of the built-up areas are close to the coastal belt and subjected to hot temperatures. Due to the diurnal temperature changes, coastal ...
Study on climate elasticity of runoff in Kalu and Kelani river basins in the wet zone of Sri Lanka

Wijekoon, WMRTY; Rajapakse, RLHL [Conference-Abstract]

It is crucial to assess the impacts due to climate change on the hydrological cycle for the characterization of basin hydrology and water resource management. Climate elasticity can be used as an indicator to quantify ...
Study on economical protective measures against concrete spalling

Senevirathne, WTL; Baskaran, K [Conference-Abstract]

Concrete spalling is a major problem in reinforced concrete structures, especially in public buildings, which were constructed some time ago. In Sri Lanka, many public buildings such as schools and hospitals exhibit this ...
Study on effectiveness of waterproofing in buildings during the design, construction, and maintenance phases of a structure

Priyashan, DMD; Fernando, PLN [Conference-Abstract]

Waterproofing is a critical aspect of building construction, ensuring longevity, durability, and structural integrity. There are several waterproofing methods used for buildings around the world. Among these, integral ...
Study on elastic modulous of carbon nanotubes using molecular dynamic simulations

Perera, LNPT; Dilrushi, KGS [Conference-Full-text]

CNTs are cylindrical nanostructures having a range of potential applications in nanotechnology. Therefore, an accurate study of mechanical behavior of CNTs is vital. Elastic modulus is an important parameter which is ...
