Type K mortar
This uses a 1 / 3 / 10 mix and results in a mortar with but a
75 psi compressive strength. Type K is useful only in historic
preservation situations where load-bearing strength is not of
importance and the porous qualities of this mortar allows very
little movement due to temperature and moisture fluctuations.
This aids in prolonging the integrity of the old or even ancient
bricks in historic structures.
To get 1 cu yd of K mortar, you need 27 cubic feet of the
components in a 1 to 3 to 10 proportion.
Portland cement
1.93 cu ft
Hydrated lime
5.79 cu ft
Sand
19.29 cu ft
Total
27 cu ft
Based on the ASTM densities, this gives you 181.42 lbs of
Portland cement, 231.6 lbs of hydrated lime and 1,543.2 lbs of
sand.
To put together a single cubic yard of type K mortar, you
need to buy:
1.93 bags of Portland cement
4.632 bags of hydrated lime
0.7716 tons of sand
Straight lime mortar
This uses a 0 / 1 / 3 mix and is used now only to recreate
the construction and review the methods of times past or
maybe for purely visual purposes. This mortar was made
before Portland cement was available in many areas and so this
is what was used. Sometimes you'll see straight lime mortar
called "L" mortar (for lime) but this is not designating it as
"type L" mortar as in the MSNOK types. There is no "type L"
mortar.
To get 1 cu yd of lime mortar, you need 27 cubic feet of the
components in a 0 to 1 to 3 proportion.
Portland cement
none
Hydrated lime
6.75 cu ft
Sand
20.25 cu ft
Total
27 cu ft
Based on the ASTM densities, this gives you no Portland
cement, 270 lbs of hydrated lime and 1,620 lbs of sand.
To put together a single cubic yard of lime mortar, you
need to buy:
No bags of Portland cement
5.4 bags of hydrated lime (50 lb bags)
0.81 tons of sand
