If boards are i-(9OG Date 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.
