Comparison should include
- identifying the applications, strengths, and use of the three most used cements: M, S, and N
- describing additives used in masonry cements (e.g., accelerators, retardants, water-repellent agents, colors, air-entraining agents)
- describing the type of cement-and-additive combination that would be best for different jobs
- considering the effects of environmental factors (e.g., temperature).
IRC: Chapters 4 and 7 cover types of cement approved for block and brick installation. Additives are also discussed in these chapters.
