This paper presents the potential use of externally bonded fiber reinforced polymer (FPR) systems to upgrade reinforced concrete slabs deficient in flexural strength. A total of five slabs,
each having 500 mm width, 125 ...
It is in the last five Abstract: years that the stakeholders of concrete paving blocks
(CPBs)areawakening to engineer the CPBs in Sri Lanka. Although large scale production of CPBs has
already flourished in Sri Lanka, ...
In the recent Abstract: past, considerable number of tower failures happened in
telecommunication sector and power transmission sector in Sri Lanka. However, no lessons were
learnt and there is still a vacuum in strength ...
A masonry infill wall is a common cell in a concrete framed building. More importantly the bond between concrete and masonry has considerable effect to the performance of
infill masonry walls and hence to the frame structure ...
The Bridge which is located in Padeniya-Abstract: Anuradhapura road is a steel truss bridge
with three spans of approximately 31m long. It is currently undergoing a development process
which includes constructing a new ...
CFRP (Carbon Fibre Reinforce Polymer) strengthening system has recently emerged as a practical alternative for the flexural strengthening of reinforced concrete structures because of its
efficiency in terms of structural ...
The strength and ductility of the concrete Abstract: can be enhanced by confinement.lt can be achieved in many ways. Using spirals is one of the ways to enhance the strength by confinement. The
confinement effect in ...
Stupas of Sri Lanka stand as proud examples for the engineering excellence of ancient
Sri Lanka. Dematamal Viharaya at Butthala is one of the oldest stupas in Sri Lanka built in the 2nd
Century BC which is a, 19m tall ...
Need for strengthening of civil engineering structures has been growing in recent times due to many reasons such as improper design, increased loading and environmental deterioration. Use of carbon fiber Reinforced Polymers ...
In Sri Lanka, almost all people have either direct or indirect connection to the groundwater resources.
Rapid urbanization, deforestation and land use changes have recently incurred adverse impacts on
groundwater recharge, ...
Construction industry is predominantly project based and quality is one of the main concerns of
customer. Hence achieving quality is one of the major tasks of a contractor. Many contractors in Sri Lanka use
ISO 9001 based ...

Recently, quarry dust has been widely used as a ground improvement technique to replace the
weak, incompetent soil under shallow foundations when there is a high groundwater table or weak soil. Practical
approaches suggest ...
Sri Lankan residual soils are formed by weathering of the metamorphic parent rock. Failure in
slopes made of such residual soils frequently occurs due to excessive rainfall. With the rain water infiltration,
soil will ...

Peat is a problematic geotechnical material, which could cause large settlements when subjected
to loading because of the consolidation effect. Other than the well known factors which can have an impact on
consolidation ...
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 ...
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 ...
The following work is based on a comparison of timber box beams with parallel chorded timber
trusses. Box type built up box beams have been adopted based on past research conducted in the Sri Lankan
context. Two types ...
Use of stone columns is a ground improvement technique that can be applied when high embankments
are to be constructed on thick layers of soft soils. Stone columns installed in an appropriate pattern,
reinforce the soft ...
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 ...
Internal curing is an emerging technology in cement concrete industry to replace the conventional
curing process by supplying excess water throughout the concrete mixture. Internally curing will outperform
in road ...
