Study the bond strength of adhered manufactured stone/thin brick veneer units and setting bed mortar at different temperatures and different cycles of freeze-thaw (Part 2)

The bond between adhered manufactured stone masonry veneer units and the setting bed mortar will be studied. It will involve testing shear, and tensile bond on small samples. Samples will consist of 2 types of adhered manufactured stones; two types of setting bed mortar (Type S, and modified dry-set cement mortar); and two types of substrates (simulated scratch coat and metal lath, and exterior grade cement board). Samples will be tested at 3 different temperatures (-40, 0 and 20°C), and 2 different numbers of freeze-thaw cycles. Three samples will be cast and tested for each combination.

Improving hygrothermal modeling as design tools using field measurements to achieve durable and energy efficient wood structures

Computer-based simulation software, called hygrothermal modeling has become increasingly popular and useful to predict and evaluate heat, air, vapour, and water-related performance of buildings. This research project aims to improve such modelling for wood construction through validation using specifically measured property data and field/lab performance data. The goal is to make modelling a more reliable design tool and to subsequently improve the design and construction of both mass timber construction and light wood-frame construction.

Develop a reliability-based robust shoring design system using Excel

The project is to develop a robust shoring design system using Excel software. A shoring system is a group of structural elements used to support/retain earth pressure during the construction of underground structures. Its design is influenced by many variables, such as the intended use of systems, earth pressure selection, performance of different systems, ground conditions, soil strength, and loading effects. Many of these variables cannot be easily interpreted, for example, accurate characterization of the highly variable glacial deposits covering the GTA.

Structural and Hygrothermal Performance of Masonry Walls with Large Cavities

A veneer wythe protects the indoor environment and other building components against adverse outdoor effects, such as rain and physical impacts. Veneer walls are connected to a structural substrate (e.g. wood frame or masonry units) by ties. These are usually made of steel and therefore high in thermal conductance. The ties penetrate the thermal insulation layer between the veneer and structural substrate and hence act as uniformly distributed point thermal bridges. In conventional thermal analysis, their presence is usually neglected.

Integrating Digital Design + Prefabrication Processes into Calgary-based Architecture and Design Firms (continued)

Many architecture and design firms in Calgary have a strong desire to incorporate parametric software (BIM) and digital manufacturing (CAD-CAM) technologies into their design processes in order to meet evolving client demands, regulatory requirements, and sustainability performance targets. These are necessary criteria that constitute high-quality built environments capable of meeting the needs of multiple stakeholders including clients as well as the general public.

Technical and Economic Assessment of Implementing UV Treatment in Potable Reuse Process Trains - Year two

Driven by climate change induced water scarcity, further enhanced by rapid urbanization and population growth, potable water reuse initiatives are gaining interest. Potable reuse involves the indirect or direct use of highly treated municipal wastewater as a municipal drinking water source. Historically, the most commonly installed potable reuse train consisted of microfiltration, reverse osmosis (RO), and ultraviolet (UV) as treatment stages.

Development of a New Test Method to Evaluate the Impact of Curing on the Near-surface Chloride Penetration Resistance of Concrete

The rate at which chlorides from deicer salts penetrate into concrete towards the reinforcing steel has a strong influence on the time-to-corrosion and service life of concrete structures. Thus, the permeability of the concrete cover layer protecting the reinforcement has to be minimized especially in severe exposure conditions. In addition to the type of concrete, the permeability of the concrete cover is influenced by early-age curing (keeping the concrete warm and wet to maintain cement hydration that fills in pores).

An Integrated Multi-Case Study Approach to Advancing Business-to-Business (B2B) Online Marketing Strategies

With the growth of the internet, online and social media marketing have replaced tv and print advertising. Many companies have become extremely savvy in the use of online marketing tools to reach consumers. But how should online marketing be used when a company is working within a business-to-business context? Online marketing techniques often do not apply in this context. Developing appropriate strategies for business-to-business companies are important as they will drive brand recognition, acquire new customers and create significant financial returns for the company.

Towards Automation of 3D Visualization & Analysis of Workspace Collisions on Construction Jobsites

Workspace Interferences/Collisions happen on construction jobsites when multiple resources (labor, equipment, material, etc.) don’t have enough space to coexist at the same time and will interfere with each other’s operations. These interferences affect performance, delaying the project, impacting cost, and may jeopardize the buildings’ integrity and people’s safety on site. Most of existing models simulate resources as being deterministic. However, the behavior of the crew interfering is more chaotic.

Volume Change Behaviour of Problematic Geomaterials

The proposed research consists of two tiers to understand the volume change behaviour of problematic geomaterials. Engineered structures have been distressed by expansive soils because of heaving and subsidence. Likewise, mine waste tailings from mineral beneficiation process must be contained in-pit storage facilities to minimize environmental impacts.
