Use of fly ash (FA) in concrete started in United States in early 1930’s. Standardized FA (SFA) by Canadian Standard Association (CSA) is frequently used as partial replacement of cement in manufacturing binary or ternary concrete mixtures. In addition to economic and ecological benefits, use of FA in concrete (a) improves workability (due to increased […]

Kruger Energy has built and commissioned a 23-MW biomass cogeneration plant at Kruger paper mill in Brompton (Québec) in 2007. The plant includes a hog boiler which burns papermill sludge, bark, and other wood residue (were firstly disposed in earth), as well as a steam turbine which generates electrical energy and provides steam required to […]

Building structures with asymmetric setbacks possess both vertical and in-plan irregularities. The former is due to the abrupt changes in the plan dimension at the level of the setback while the latter results from the asymmetry between the upper tower portion and the lower base portion. An asymmetric setback introduces mass, stiffness and resistance eccentricities […]

In 2000, road traffic congestion in USA alone caused 3.6 billon vehicle-hours of delay, 21.6 billion liters of wasted fuel, and US$67.5 billion in lost productivity. Yearly estimates on economic, health, and environmental cost of traffic congestion in New Zealand is in excess of NZ$1 billion [Hazelton, 2010]. Traditionally, traffic modelling has concentrated on simulating […]

The Champlain Sea, an inland sea, invaded the Saint Lawrence River valley in Southern Quebec at the end of the last glaciation, from 12 000 to 10 000 years ago. During this marine transgression, thick clay deposits were emplaced in Southern Quebec. The thickness of these Champlain clay deposits can reach 100 m at the […]

With the increasing scarcity of water resources throughout the globe, many jurisdictions have turned their attention to the protection, remediation and enhancement of existing freshwater sources. The primary aim of this research will be to develop and assess a novel roadside treatment system which has the capacity to capture, detain, and infiltrate the suite of […]

The research project is to model the Ontario power grid and its constituent zones in order to determine the best locations for wind turbine farms and distributed power sources. A basic model of the Niagara Zone has been constructed, involving the location of the power generation stations, major demand centres, and transmission systems. The model […]

This project is designed to verify the performance of a wireless Smart-Rock™ sensor that is embedded in concrete during construction for non-destructive quality control at low temperatures. Various laboratory experiments will be conducted using the smart sensor at Queen’s University on different concrete mixtures at low temperatures. The data from these sensors are analyzed using […]

The proposed research project is on asphalt rehabilitation materials called cold in-place recycling (CIR) and full depth reclamation (FDR). Those pavement rehabilitation techniques are gaining popularity because of their lower cost and their lower environmental footprint than conventional pavement reconstruction. In both case, asphalt pavement, and a part of the granular base for FDR, are […]

The St. Lawrence River harbours a complex ecosystem whose physical properties vary from upstream to downstream. It includes lakes and freshwater reaches, a long estuary, and a gulf with marine features. The area is home to richly diverse habitats and an equally rich diversity of flora and fauna. It is a natural resource to be […]

The two last years, the emergence of car mobile applications (Uber for example) has disturbed the taxi industry. This new market is becoming more predominant and no solution has been found to reach an objective equilibrium with the older modes of transport. This problem is appearing all around the world with different companies depending on […]

Considering the unique properties of CO2 under supercritical condition, CO2 is proposed to be used in huff-and-puff treatments to enhance shale gas recovery from shale gas formations. This research project will look at the fundamental pore-scale mechanisms when CO2 huff-and-puff is used for enhancing methane recovery from shale formations. In order to obtain pore-scale mechanisms […]
