  • Masonry - Wikipedia

    Masonry has high compressive strength under vertical loads but has low tensile strength (against twisting or stretching) unless reinforced. The tensile strength of masonry walls can be increased by thickening the wall, or by building masonry piers (vertical columns or ribs) at intervals.

  • Masonry Mortar Types - archtoolbox.com

    Type O mortar is sometimes used with masonry units that have a low compressive strength (i.e. sandstone or brownstone) so that the mortar allows more flexing, which prevents cracks in the units. Type O Mortar Uses: Interior non-load-bearing applications with very limited exterior use.

  • compressive strength of tiles adhesive - gent1913-1918.be

    Compressive strength is the maximum compressive stress that a sealant can withstand without breaking down or experiencing excessive extrusion from the joint. Compression set is the inability of a sealant to return to its original dimension after being compressed.

  • Aggregates - Portland Cement Association

    In general, if the water-cement ratio is chosen correctly, a wide range in grading can be used without a major effect on strength. When gap-graded aggregate are specified, certain particle sizes of aggregate are omitted from the size continuum. Gap-graded aggregate are used to obtain uniform textures in exposed aggregate concrete. Close control of mix proportions is necessary to avoid segregation.

  • Preservation Brief 2: Repointing Mortar Joints in Historic ...

    A mortar that is stronger in compressive strength than the masonry units will not "give," thus causing stresses to be relieved through the masonry units—resulting in permanent damage to the masonry, such as cracking and spalling, that cannot be repaired easily.
