Document Summary
Chap 1 - historical background, materials and structural systems, 187) and factors affecting the compressive strength, flexural tensile strength, shear strength: masonry units: (clay) bricks. Solid masonry if cross sectional area > 75% of gross area (ie cores < Bricks with no cores are usually laid frog up (concrete) blocks. For face shell bedding (common) only the shaded area is mortared. Hollow masonry if cross sectional area < 75% of gross area. Csa a82-06 gives testing (sampling) requirements, tolerances, etc. for brick, 2 common types in canada (type n, type s): **type n is best less strength but better bond. Increase in strength of type s is not really worth decrease in other. Type n with mc is not as good as type n with pc and lime. Desirable properties (cured/hard state): bond (ability to hold units together) without allowing water to penetrate, bond strength (flexural tensile strength) in mpa, compressive strength.
