The Applied Technical Services Family of Companies (ATS FoC) conducts mortar testing in accordance with ASTM C270. This standard defines mortar types for unit masonry, sets proportioning rules, and outlines performance evaluation methods. It specifies mortar types including N, S, M, and O, each with designated uses and minimum strength requirements. Our technicians follow ASTM C270 for mix design review, sampling, and routine testing to ensure mortar meets project specifications and building codes.
What Are the ASTM C270 Requirements for Mortar?
ASTM C270 establishes requirements for mortar used in reinforced and non-reinforced unit masonry. It classifies mortar into Types M, S, N, and O. Compliance is determined using either the Proportion Specification or the Property Specification, as designated by the project requirements. Key requirements include:
- Proper proportions of cementitious materials, lime, and aggregate
- Minimum compressive strength, water retention, and maximum air content when the Property Specification applies
- Verification that specified materials are used and properly proportioned
About Our Capabilities and Credentials
Our concrete testing laboratory conducts petrographic examination, aggregate lithology identification, mineral characterization, and evaluation of potentially deleterious constituents in accordance with ASTM C295. We provide detailed analysis of aggregate composition, texture, weathering, alteration, and other factors affecting concrete performance. Our laboratory uses calibrated equipment and controlled procedures to ensure reliable results. Our quality system includes documented quality-control procedures and laboratory accreditation, including ISO/IEC 17025 within the accredited scope. We deliver clear technical reports and expert interpretations to support informed material selection and quality control decisions.
How Can ASTM C270 Testing Verify Mortar Compliance?
Technicians prepare representative mortar samples from the job site or production batches, cure them under controlled conditions, and test compressive strength using standardized procedures. Results are compared to specified type or property limits. Additional checks verify material proportions, measure consistency, and confirm that constituent materials meet referenced standards. A comprehensive test program identifies nonconforming batches, supports corrective actions such as mix redesign or process adjustments, and provides traceable documentation for project records.
