PUBLICATIONS AND WORKING PAPERS
Developing a National Education Strategy for the National Guide to
Sustainable Municipal Infrastructure (the Guide)
S. Easa, L. Amleh
A first for Canada, the Guide provides a road map for municipal officials and
others to the best available solutions to today's municipal infrastructure
challenges. This six-month research contract is will develop a national
education strategy that is expected to achieve the Guide's vision of becoming a
dynamic source of leading/relevant municipal infrastructure practices. The
strategy will also help educate practitioners and decision-makers on the Guide's
use and content. (Funding Agencies: Federation of Canadian Municipalities, 2003
- 2004)
Corrosion and Deterioration of Bond at the Steel-Concrete Interface
L. Amleh, A. Ghosh
The influence of some of the significant parameters influencing the behavior of
corroded bars, such as the concrete strength, crack width, extent of rebar
corrosion (measured by the mass loss), concrete cover thickness, bar diameter
and the loss of the rebar lugs is studied. Based on consideration of the various
trends observed, a framework for design of structural concrete for durability
against deterioration of bond at the steel-concrete interface due to corrosion
of rebars will be developed. (Funding Agency: NSERC, 2003 - 2004)
Bond Deterioration of Different Types of Reinforcing Bars in Concrete Due to
Corrosion
L. Amleh, A. Hassan
The aim of this research is to study the effect of corrosion on bond strength
using four different types of concrete (Sundance fly ash concrete mix, Silica
fume concrete mix, normal concrete mixture with 0.32 water/cement ratio, and
high water/cement ratio concrete mixture with 0.52). Each type of these
concretes has three different steel types embedded (regular carbon steel,
stainless steel and pre-damaged epoxy coated steel bars). (Funding Agencies:
NSERC, 2001 - 2003)
Finite Element Analysis of Corrosion and Bond-Slip
L. Amleh, Y. Lan
An analytical study based on fracture mechanics was carried out to investigate
the behavior of three different types of reinforced concrete specimens. The
nonlinear finite element program ATENA with the nonlinear material models for
concrete, reinforcement bar and bond-slip is used to analyze cracking
propagation and bond failure process. The influence between corrosion and bond
slip in RC structure is also studied. (Funding Agencies: NSERC, 2001 - 2003)
The Effect of Water Cement Ratio on the Ingress of Sodium Chloride in Concrete
Structure
L. Amleh, U. Mehta
The primary purpose of this investigation is to understand how water cement
ratio affects the ingress of sodium chloride in concrete structures. (Funding
Agencies: NSERC, 2001 - 2002)
Bond Deterioration of Reinforcing Steel in Concrete Due to Corrosion
L. Amleh
The basic objectives of this research program are to study the influence of
increasing levels of corrosion on the progressive deterioration of bond between
the steel and the concrete and to determine the extent to which the various
cements and mix proportions influence the corrosion of the reinforcement as a
function of the chloride ion penetration phenomenon. (Funding Agencies: NSERC,
2000)
Evaluation of Corrosion Response of a Decommissioned Deteriorated Bridge Deck
L. Amleh
This research program consists of laboratory studies of the corrosion phenomenon
and field study of the deterioration due to corrosion of the Dickson Bridge,
Montreal. This research program was a part of a detailed strategic program to
determine why the Dickson Bridge in Montreal deteriorated so prematurely and to
create a data bank from many electrochemical, chemical, physical and mechanical
tests on the various bridge components. (Funding Agencies: NSERC, 2000)
