A collaborative effort between Auburn University and construction professionals will allow visitors to the Southeastern Raptor Center to have better and safer viewing of birds of prey from an environmentally friendly walkway. Students in a Structures III class taught by Michael Hein, a professor in the McWhorter School of Building Science, working with Auburn Facilities Division and private contractors, prepared the site and placed the more than 300 linear feet of pervious concrete — a material that supports load while it allows water to pass through and reduces

TECHNICAL REVIEW

LABORATORY VS. FIELD TESTING OF MORTAR BILL GOODLOE

Technical Services Manager, CEMEX

When

project

specifications

require

mortar to be tested at the jobsite, it often becomes an issue because the proper procedures for field testing of mortar are commonly misunderstood. Consequently, improper methods are used and failing tests are often reported. ASTM C270, “Standard Specification for Mortar for Unit Masonry”, has requirements for compressive strength, however, it is a laboratory test, not a field test. What many people do not realize, is that there is not a field test for compressive strength that can, or should be, used for acceptance. ASTM C270 provides specifications for mortars for use in the construction of nonreinforced and reinforced unit masonry structures. The mortar may be specified by either the proportion specification or the property specification. There are no strength requirements for the proportion specification. The property specification outlines 28 day strengths for Types M, S, N, and O mortar. The strengths are tested in the laboratory. The water content of the mortar made in the laboratory is much less than the water content of the mortar that is mixed in the field. The reason that it contains less water is to try and simulate the mortar after it has been subjected to the “wicking” action of the masonry units, which draw water out of the mortar. Mortar that is tested in the field is not subject to the strength
