“M” (Mortar Type)
strongest, below grade, high loads, severe frost, not workable
“S” (Mortar Type)
exterior reinforced masonry, seismic loads
“N” (Mortar Type)
general purpose
“O” (Mortar Type)
low strength, interior or non load bearing walls
“K” (Mortar Type)
very low strength and no longer used
Should mortar be weaker than brick?
Yes
What is the average mortar height?
3/8” (ranges from 1/4” - 1/2”)
FBS (Facing Brick)
- most common appearance grade, some chips, similar dimensions
- fbStandard
FBX (Facing Brick)
- less chips, more uniform
- fbeXactly the same”
FBA (Facing Brick)
-more chipping
SW (brick)
“snow brick”
hardiest
MW (brick)
“Miami brick”
middle range
NW (brick)
“iNterior brick”
weakest
N (hydrated lime)
normal
S (hydrated lime)
special - more water content so more work-ability, more $$
Type I (Portland Cement)
-most commonly used, “normal”
Type IA (Portland Cement)
- air entrained
- most commonly used, “normal”
Type II (Portland Cement)
- concrete with moderate resistance to sulfites
- used at ground where water has sulfites
- generates less hear so good for warm weather climates
Type IIA (Portland Cement)
- air entrained
- concrete with moderate resistance to sulfites
- used at ground where water has sulfites
- generates less hear so good for warm weather climates
Type III (Portland Cement)
- high early strength
- used for pre-cast cold weather construction
Type IIIA (Portland Cement)
- air entrained
- high early strength
- used for pre-cast cold weather construction
Type IV (Portland Cement)
- low heat of hydration
- used for dams and other large structures
Type IVA (Portland Cement)
- air entrained
- low heat of hydration
- used for dams and other large structures
Type V (Portland Cement)
- High sulfite resistance
- There is no Type VA!
