Masonry in IBC Code
Masonry in IBC Code
(OP)
In the IBC 2003 Code there is a table that summarizes properties of types of mortar. What is the difference and where would I find/use these different types (cement-lime, mortar-cement, and masonry-cement) What is normally used? Thanks.

As you are aware, the main design referenced standard IBC chapter 21 is based on is the MSJC Code and Specs (ACI 530/530.1). MSJC Code Section 1.13 SEISMIC DESIGN REQUIREMENTS provides the information you seek....and is consistent with the info JAE provided above. Refer to MSJC Code Sections 1.13.6.6 (SDCD), and 1.13.7.1 (SDC E and F).
For SDC A thru C it would then appear that Types M, S, and N cement-lime, mortar-cement, and masonry-cement mortars are permissible for structural masonry depending on amongst other factors, the level of design stresses involved. In the UBC, masonry-cement mortars are not permitted in SZ 2, 3 and 4..and I wonder why this is allowed by the MSJC Code for SDC C. Perhaps the cement industry folks had more clout with MSJC than the lime industry folks.
