Sustainable decentralized waste management in urban residential areas

Philip, L; Makkar, S; Ramprasad, C [Conference-Abstract]

Proper management of wastewater is a major challenge for a developing country like India. The scarcity of water in urban areas has given rise to the requirement of reuse of treated wastewater for secondary uses. Large ...
Application of lean concepts in the construction industry

Madushan, STK; Hathurusinghe, HDDC; Dissanayake, PBG [Conference-Abstract]

Sri Lanka is a developing country experiencing a huge construction boom. All construction use various types of resources and waste of resources occur at all construction sites. These wastes include not only material resources ...
Economies of off-site concrete construction with BIM

Jayasena, HAEC; Yoosuff, MYAIM; Jayasena, HS [Conference-Abstract]

Off-site concrete construction (OSC) and Building Information Modelling (BIM) are certainly not new to the construction industry. However, current construction trends, increasing awareness in efficient construction, the ...
Load testing of bridges for load rating

Peiris, A; Harik, I [Conference-Abstract]

The AASHTO load rating method, which is the standard for determining the live load carrying capacity of bridges in the United States, is based primarily on the as-built material and section properties of a bridge. This ...
Investigation on neutralizing agents for palm oil mill effluent (POME)

Kalansuriya, MH; Mowjood, MIM; Dharmasena, DAN [Conference-Abstract]

Proper treatment of palm oil mill effluent (POME) is necessary to sustain the progress of palm oil industry in Sri Lanka. A case study was conducted to improve existing wastewater treatment system in a palm oil factory ...
Application of a process-based, distributed, hydrological and material transport model to assess water resources and pollute transport in malwathu oya basin, sri lanka

Dahanayake, AC; Rajapakse, RLHL [Conference-Abstract]

The Water and Energy transfer Processes Model – WEP Model is a distributed, physically based hydrologic model that has been coupled with a material transport component. The model uses meteorological, geographical, hydrological ...
Production of lab scale limestone calcined clay cements using low grade limestone

Medepalli, S; Shah, V; Bishnoi, S [Conference-Abstract]

In developing countries, such as India, cement production is expected to rise exponentially in the coming decades with the increasing infrastructure demand. Sustainable alternatives are being looked into to account for the ...
Comparison of design, cost and duration of LGS and SCIP construction with conventional RC construction

Qureshi, LA; Nosheen, H; Amir, MT; Hussain, S; Raza, H [Conference-Abstract]

The research work presented in this paper was planned to have a comparison between “Cold Roll Light Gauged Steel (LGS)”, “Structural Concrete Insulating Panel (SCIP)” and conventional “Reinforced Concrete (RC)” constructions. ...
Performance characteristic of sustainable ternary cements

Shah, V; Mishra, G; Bishnoi, S [Conference-Abstract]

Cement production leads to an emission of approximately 0.87 ton of CO2 for each ton of cement produced, which accounts for 7-8% of global CO2 emissions. To minimize these emissions, various alternative materials or waste ...
Studies on reactivity of limestone-calcined clay cement for sustainable infrastructures

Mishra, G; Parashar, A; Bishnoi, S [Conference-Abstract]

In the present scenario, urbanisation is accelerating at an exponential rate all around the world and approximately 70% population is expected to be living in urban areas by 2030. This rapid urbanization has created a ...
Inverse modelling for estimating an interface element properties in soil-pipe interaction an optimization approach

Kathirgamanathan, P; McLachlan, R [Conference-Abstract]

The development of transmitted stresses onto a pipe from the backfill or in-situ soil is not well known for both static and dynamic load cases. This study was aimed at investigating the application of an inverse modelling ...
Reactivity of blended SCMC for sustainable ternary cements

Parashar, A; Shah, V; Bishnoi, C [Conference-Abstract]

The Cement industry is responsible for huge CO2 emission; still, numerous efforts are being applied to increase the efficiency of cement plants. The CO2 emissions from cement production can also be reduced by replacing ...
Preparation of extension of time (EOT) claims and delay analysis techniques used in the construction industry

Maduranga, JAM; Palamakumbura, APWMGM; Dissanayake, PBG [Conference-Abstract]

Delays are one of the most common issues faced by construction projects in Sri Lanka. Most of the cases are complex and difficult to analyse. Various delay analysis methods have been developed and used in the construction ...
Compressibility behaviour of peat stabilized with low calcium fly ash an experimental study

Mathiluxsan, S; Venuja, S; Nasvi, MCM [Conference-Abstract]

Peat is a kind of soft organic soil having partially disintegrated plant remains hence it is not good for constructions. Chemical stabilization is the commonly used ground improvement technique by adding chemical admixtures ...
Effect of low calcium fly ash (ASTM class f) on the stabilization behaviour of expansive soil

Dissanayake, TBCH; Senanayake, SMCU; Nasvi, MCM [Conference-Abstract]

Expansive soil experiences swelling with the addition of water and then shrink after the removal of water. These alternate wetting and drying impose lot of problems to the structures built on expansive soils. Ground ...
Numerical simulation of settlement behaviour of axially loaded piles used for high-rise building

Gowthaman, S; Nasvi, MCM; Krishnya, S [Conference-Abstract]

The reliable prediction settlement of pile foundation at typical working load remains one of the major geotechnical engineering problems. In this research, settlement behaviour of a pile foundation located in sandy-silt, ...
Impacts of non revenue water on the national water supply and drainage board and methods to minimize it

Malithi, WPP [Conference-Abstract]

Non-Revenue Water (NRW) could be known as the gap between the volume of water which is put into a water supply system and the volume of water which is billed as authorized consumption. NRW is a major encounter to all the ...
Experimental investigation on shear capacity of lipped channel beams with non-circular web openings

Wanniarachchi, KS; Priyadarshani, WAP; Piratheep, P [Conference-Abstract]

Cold-formed steel members are increasingly used around the world due to the availability of thin and high strength steel and advanced steel technologies. Sri Lanka as a fast growing economy in Asia requires new technologies ...
Environmentally responsible selection and management of construction materials in disaster reconstruction

Fonseka, C; Hettiarachchi, M; Van Breda, A; Elwood, JP [Conference-Abstract]

Disaster reconstruction has become an important component in built environment planning in recent decades as the frequency, scale and intensity of both natural and manmade disasters are increasing globally. Despite the ...
Contextualized enhancement of vocabulary in the context of ESL learning

Muthulingam, A [Conference-Abstract]

Learning is an active and dynamic process in which individuals can perceive a variety of information and strategic modes of processing. Learning strategies are made as procedures undertaken by the learners in order to make ...
