  1. PROCEEDINGS OF THE 2nd MASONRY MINI SYMPOSIUM [Download]

    Title: PROCEEDINGS OF THE 2nd MASONRY MINI SYMPOSIUM
    Creator: Korany, Yasser
    Description: The 2nd Masonry Mini Symposium is part of the graduate level course: Behaviour and Design of Masonry Structures that was taught in the spring of 2010. Course participants were asked to work in groups to write technical papers on topics relevant to masonry systems. They presented their findings to a panel of professional, engineers, architects, contractors, and building official on the evening of March 30th 2010. This year’s theme was underutilized masonry systems. In this report, the reader will find a compilation of the edited manuscripts of all papers presented during this event.

    Title: Proceedings of the 3rd Masonry Mini Symposium
    Creator: Y. Korany
    Description: The 3rd Masonry Mini Symposium is part of the graduate level course: Behaviour and Design of Masonry Structures that was taught in the spring of 2011. Course participants were asked to work in groups to write technical papers on topics relevant to masonry systems. They presented their findings to a panel of professional, engineers, architects, contractors, and building officials on the evening of April 7th 2011. This year’s theme was masonry building envelope systems. In this report, the reader will find a compilation of the edited manuscripts of all papers presented during this event.

  4. CONCRETE MASONRY COMPRESSIVE STRENGTH USING THE UNIT STRENGTH METHOD FOR GROUTED MASONRY [Download]

    Title: CONCRETE MASONRY COMPRESSIVE STRENGTH USING THE UNIT STRENGTH METHOD FOR GROUTED MASONRY
    Creator: M. Ross
    Description: The objective of the analysis summarized in this report is to re-establish the correlation between unit strength and prism strength using more recent test results. These correlations were examined using a large database of available test results of prism testing conducted in North America. The analysis presented in this report is intended to be complementary to a report based on hollow masonry construction, also prepared in the University of Alberta (Gayed, 2011), and parallels a similar research project performed by the National Concrete Masonry Association in the United States (NCMA, 2012).

  6. APPLICATION OF POLY-MOR FOAM AS INSULATION FOR SINGLE WYTHE MASONRY WALLS [Download]

    Title: APPLICATION OF POLY-MOR FOAM AS INSULATION FOR SINGLE WYTHE MASONRY WALLS
    Creator: Ross, Michael
    Description: Unfinished single-wythe concrete masonry walls are commonly used in warehouse and industrial settings to enclose the building. Single-wythe concrete masonry walls are relatively inexpensive to construct while simultaneously providing security and durability due to superior resistance to impact, fire, weather, insects, and corrosion. The main drawback of single-wythe walls is that they provide little thermal resistance. Under the recently superseded Model National Energy Code of Canada for Buildings (MNECB), single-wythe masonry walls meeting certain criteria were exempted from being insulated (NRCC 1997). The new National Energy Code of Canada for Buildings (NECB) has significantly stricter energy efficiency guidelines for building envelope design and provides no exemption for masonry walls (NRCC 2011). This, in addition to growing concerns regarding anthropogenic effects on the environment and increasing energy prices, has given rise to the need for an inexpensive and efficient option to insulate single-wythe masonry walls. The purpose of this investigation was to evaluate the effectiveness of POLY-MOR polyurethane foam as an insulating material and determine the best procedure for applying the foam. Three different application methods were investigated using two different foam densities and three different thicknesses. POLY-MOR foam was applied to unfinished single-wythe concrete masonry walls. The polyurethane foam was applied by spraying, formwork filling, or core grouting. Tests were conducted according to ASTM standards to determine the density and thermal conductivity of the foam in each application. A two-dimensional heat flow simulation was then used to determine the effective RSI-value of masonry walls with the different insulation configurations. Although the test specimens were concrete block walls, the results of the investigation could be relevant for insulating slabs, roofs, and other wall constructions.
