Actual Sizes depends on the Manufacturer MASONRY LECTURE #1 (cont’t)

5. 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)
