Use this CSI 3 part SimpleSpecs™ master specification to specify masonry mortaring for use in masonry construction referenced in other masonry sections.
Mortar may be specified in one of two ways:
– Proportion method: The quantities of cement, sand, and lime are specified, typically expressed as a range, that will provide the required mortar attributes.
– Property method: Mortar is specified by the required compressive strength, with proportions left up to the mason.
In general, higher compressive strengths result in less flexible mortar. Flexibility is important in that it allows the masonry construction to move to some degree without damage. This does not preclude the use of properly located and sized control joints in the masonry.
In no case should the mortar be higher in compressive strength than the masonry units. Lower compressive strength mortar allows for the mortar to be damaged under movement; mortar is much more easily replaced than masonry units.
Color additives can be added to the mortar; pre-packaged mortar mixes are often available in multiple colors.
Other additives may be added to mortar to improve certain characteristics, such as decreasing water absorption and increasing the working time of the mortar.

The SimpleSpecs™ master specs concept
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable. In fact, quite the opposite is true. Having shorter, easily understood specifications makes us less likely to have problems in the field.
A belief that having lots of words protects us from a Contactor making mistakes. There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit
SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.
Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.
Hidden Guide Text
Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.
SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually. Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
