Type N Mortar Cement is manufactured to meet the flexural bond strength required by some specifications without having to use Portland-Lime cement mortars. It pairs proportioned convenience with the bond performance engineers look for in code-governed masonry. This cement meets ASTM C1329 specifications.
Mortar cement occupies its own place in the standards for a reason. Lower limits on air content result in higher flexural bond strength. The finished joint grips the unit harder, which matters when a wall has to resist out-of-plane forces. For the mason, it still mixes and lays like a familiar mortar.

Bond and compressive strength figures, plus the standards this cement meets, are laid out in the product data sheet.
The safety data sheet should be reviewed first. It addresses handling, storage, and protective equipment.
