12 Explanatory Notes NUMBER DESCRIPTION 1 Due to manufacturing process, dimensions may exceed minimum requirements. 2 Equivalent thickness is the net thickness of a unit, other than a solid unit, re-shaped to form a voidless unit having the same height and length dimensions (190mm x 390mm) and is a direct function of percentage solid content. Therefore, the overall width of a non-solid unit multiplied by its percentage solid content will arrive at its equivalent thickness ratio. The percentage solid content equals net volume (as defined in The Supplement to the National Building Code) divided by gross volume. e.g. Calculating Equivalent Thickness: 20cm Hollow Concrete Block Percentage Solid 5% as per CCMPA specification Equivalent Thickness = Equivalent Thickness = Actual Width x Percentage Solid 5 = 190mm x mm 3 Gross, defined by the CSA-A15.1, is the area parallel to the bearing surface of the masonry unit by calculating the actual measured overall dimensions of the unit including the voids. is the net cross-sectional area at mid-depth of the unit. This area can be calculated using actual Gross multiplied by percentage solid of unit. 5 Core is the measurement of the core areas taken at mid-height of unit. Gross, as defined in Supplement to the National Building Code is: Equal to the actual length of the unit multiplied by the actual height of the unit multiplied by the actual thickness of the unit. 7, as defined in Supplement to the National Building Code is: Determined by using a volume displacement method that is not influenced by the porous nature of the unit. 8 Refer to CCMPA Specifications for concrete density (kg/m3). Typical Average Weight of Type A Concrete 2100 kg/m 3 Typical Average Weight of Type C Concrete 1750 kg/m 3 Typical Average Weight of Type D Concrete 150 kg/m 3 9 Fire Ratings are based on the Supplement to the National Building Code. 10 For more detailed information, refer to Section 7 Sound Properties. 11 Refer to Section Thermal Properties, for detailed information. w w w. c c m p a. c a -11
