  • Provides for “full” bearing MASONRY UNITS IRREGULAR “ CUSHIONS” FULL BEARING Seals between masonry units WATER WIND Adheres / bonds masonry units STRUCTURAL BOND Aesthetics USUALLY 20% OF SURFACE IMPORTANT CONSIDERATION GENERALY “ MOCKUP” ARCHITECT / OWNER APP’L PRIOR TO THE START OF MASONRY
  • Portland Cement SAME AS THE INGREDIANT IN CONCRETE BONDING AGENT Hydrated Lime ENHANCES WORKABLITY Sand CLEAN GRADED Water CLEAN (POTABLE) Admixtures (optional) WORKABILITY COMMON IN PRE-PACKAGED
  • REFER TO PAGE 269 Course HORIZONTAL LAYER OF MASONRY UNITS Head & Bed Joints Wythe VERTICAL LAYER OF UNITS - ONE UNIT THICK Stretcher FACE PARALLEL TO WALL LONG DIMENSION HORIZONTAL Header LAID TO BOND TWO WYTHES TOGETHER Soldier LAID ON ITS END FACE PARALLEL TO WALL USES- VISUAL EFFECT Rowlock LAID ON ITS FACE END VISIBLE USES - CAPS, SILLS SLIDE 4280-3
  • Molding process EXTRUSION PRESSED MOLDED (HAND OR MACHINE) Color BASED ON CLAY COMPOSITION ADDITIVES / CHEMICALS FIRING PROCESS Size APPEARANCE, COST TO INSTALL Grade RESISTANCE TO WEATHERING THREE GRADES Type BASED ON THE DEGREE OF UNIFORMITY OF SHAPE DIMENSION TEXTURE COLOR HIGH UNIFORMITY TO NON-UNIFORM
  • No “standard” size SOME “COMMON” BRICK SIZES “Normal” coursing - 3 bricks = 8” MATCH CMU COURSING Larger sizes MORE ECONOMICAL TO LAY HIGHER STRENGTH BUT - CHANGE WALL APPEARANCE Custom Shapes & Colors AVAILABLE - BUT LEAD TIME COST
  • Structural Bonds USE “HEADER” TO TIE WALL TOGETHER Cavity (Veneer) Walls BRICK DOES NOT PROVIDE STUCTURAL SUPPORT BRICK IS FOR Appearance & EXTERIOR Barrier DON’T NEED HEADERS - INFACT WOULD BE IN THE WAY OF CAVITY HEREFORE Commonly USE - Running bond Stacked bond
  • Layout & Leads ESTABLISH “LINE” & “ELEVATION” LEADS - ESTABLISH WALL PLANE & COURSE HEIGHT OFTEN - CORNERS Line LITERALLY - STRETCH A LINE & LAY BRICK / BLOCK TO IT Staging HEAVY MATERIAL Difficult to USE LADDERS - NEED STAGING ESTABLISHING A WORK PLATFORM” SCAFOLD BUILT IN PLACE, ADJUSTABLE SCAFOLD, AUTOMATED SCAFOLDING Cutting Masonry HAMMER, DIAMOND BLADE (H2O COOLED) EXPENSIVE, - DESIGN ATTEMPTS TO Minimize Cleaning Masonry BRUSHED & ACID CLEANED (PROTECTION OF OTHER SURFACES)
  • PURPOSE - PROVIDE SUPPORT AT OPENINGS Lintels Reinforced Concrete OFTEN PRECAST & SET IN PLACE Reinforced Brick RARELY USED Steel Angles ECONOMICAL ALMOST INVISIBLE MOST COMMON - SINGLE W/VENEER Arches BUILD OUT OF MASONRY NEEDS TEMPORARY SUPPORT MORE LABOR INTENSIVE (MORE $) ALSO - WINDOW/DOOR MORE EXPENSIVE ASTHETICS

    • 1.  
    • 2. Definitions & History Mortar Brick Masonry Concrete Masonry Stone Masonry Brick Masonary That’s Masonry not Mason a ry….dummy! University of Virginia Library Thomas Jefferson – Architect Third President of the United States.
    • 3.  
    • 4.  
    • 5.  
    • 6. Very very very brief History
      • Native field stones piled upon one another without mortar
      • Sod or dried mud
      • Clay & silt
      • 1000 A.D. The Romans: perfected arch and vault, built forum buildings, theaters, baths, aqueducts & homes – temples like the Parthanon!
      • Mud joints
        • Kept out wind & rain
        • Gave a level building surface
    • 7. Mortar Functions
      • Provides for full bearing
      • Seals between masonry units
      • Adheres / bonds masonry units
      • Aesthetics
      • 20%± of wall area
      • Affects the color and texture of masonry wall
      • Mortar specified in testing standard ASTM C-270
    • 8. Mortar Ingredients
      • Portland Cement
      • Hydrated Lime
      • Sand
      • Water
      • Admixtures (optional)
    • 9.
      • TYPES OF MORTAR: “MSNOK”
      • Type "M" (High): Strength (2500 psi)
      • High lateral and compressive loads & below grade uses
      • Type "S" (Medium-High): Strength (1800 psi)
      • High flexural and normal compressive loads (most common)
      • Type "N" (Medium): Strength (750 psi)
      • General above grade uses (almost useless)
      • Type "O" (Medium-Low): Strength (350 psi)
      • Non-Load bearing walls (pretty useless)
      • Type "K" (Low): Strength (75 psi)
      • Non-Load bearing where permitted (fairly useless)
    • 10.
      • Brick Positions:
        • Stretcher
        • Header
        • Soldier
        • Shiner
        • Rowlock
        • Sailor
    • 11.
      • Course: Continuous layer
      • Wythe: Continuous vertical section
    • 12. Basic Brickwork Terminology Bed Joint Head Joint Course - horizontal layer of brick
    • 13. Basic Brickwork Terminology Header - Bonds two wythes together Wythe: vertical layer 1 unit thick Soldier - Laid on its end, face parallel Rowlock - laid on face, end visible Stretcher - long dimension horizontal & face parallel to the wall
    • 14.
      • Corbel Shelf or ledge formed by projecting successive courses of masonry out from the face of a wall
    • 15.
      • Quions Stone blocks used to form strong corners.
    • 16. Considerations in Choosing Brick
      • Molding process
      • Color
      • Size
      • Grade
      • Type
    • 17.
        • “ Molded” or “Handmade”
        • solid units
        • pressed into fiberglass, wood or steel molds
        • used to be by hand, now machines
        • sand or water coated molds to release bricks
        • usually rougher surface and edges
    • 18.
      • EXTRUDED pushed through a dye & then cut by wire “kinda’ like square toothpaste”
        • hollow core
        • formed into a column and cut to size with wires
        • usually smoother surface and finer edges
      However, most brick is……….

    • 20.
      • Firing Process:
        • PERIODIC KILN
        • TUNNEL KILN
    • 21. Brick Masonry - Sizes and Shapes
      • No standard size
      • Normal coursing - 3 bricks h = 8” (including mortar joints so it aligns with 8” block (CMU)
      • Larger sizes mostly for economy
      • Custom Shapes & Colors ($$$$$)
    • 22.
      • Sizes:
        • MODULAR 8”
        • STANDARD 7 5/8”
        • THREE-INCH
        • OVERSIZE
        • ROMAN
        • NORMAN
        • SIX-INCH JUMBO
        • JUMBO
    • 23. Brick Masonry Important Qualities
      • Grade:
        • Weatherability: evaluates how the bricks will hold up to weather exposure (freeze/thaw, rain, etc.)
    • 24.
      • Grades:
        • Facing Bricks: evaluates the uniformity of shape, dimension, texture & color
    • 25. Brick Bonds
        • Running bond
        • Stacked bond
    • 26.
      • Brick Joints
