MASONRY LECTURE

MASONRY LECTURE • Overview of Masonry Terminology • Brick Joints in the wall (Chapt 15 -Nunnally) • Flush • Struck • Weather • Concave • Vee • Raked • Brick Sizes • Standard Modular (nominal, actual, joint thickness) (4 x 2 -2/3 x 8) (3 -5/8 x 2 -1/4 x 7 -5/8) (3/8”) “” (3 -1/2 x 2 -1/4 x 7 -1/2) (1/2”) • Economy • Utility Note: Holes are there to keep bricks light and cost effective. Actual Sizes depends on the Manufacturer

MASONRY LECTURE • Mortar/Bond Strength • Masonry Cement Mortar is a combination of Portland Cement, hydrated lime, & sand • Masonry Cement Mortar is used for Workability(admixture is used for air-entrainment -give mortar its fluffiness) • Bond strength is not an issue for reinforced masonry • Bond Strength is a function of water mix (the wetter the better), depends on how mortar and units are placed(better suction) • Proportioning the mortar is done empirically (cook book method) • Blocks/bricks will normally fail first because they are taller • Prisms and Mock ups are tested before construction

MASONRY LECTURE #1 (cont’t) • Mortar/Bond Strength(refer to Chapter 15 -P. 427) M A S O N W O R K - only used now for tuck pointing PM and PL used in reinforced masonry
