The Applied Technical Services Family of Companies (ATS FoC) offers ASTM C1567 testing to assess potential alkali-silica reactivity (ASR) in aggregate and cementitious mixes. This accelerated mortar-bar method measures expansion to identify combinations that may cause ASR. Engineers and material producers use these results to evaluate mixtures and select effective expansion control strategies.
What Materials Can Be Evaluated With ASTM C1567 Testing?
ASTM C1567 evaluates the interaction between aggregates and cementitious materials, rather than the aggregate alone. It assesses mixtures containing potentially reactive aggregates with Portland cement, supplementary cementitious materials (SCMs), or other pozzolanic materials. Depending on your project, the evaluation may include:
- Fine or coarse aggregate materials with potential ASR reactivity
- Supplementary cementitious materials and pozzolanic materials
- Portland cement and blended cementitious systems
This method measures mortar bar expansion under accelerated conditions. Clients use the results to compare material combinations, identify those prone to excessive expansion, select aggregates, develop mixtures, and mitigate ASR risks.
Our ASTM C1567 Testing Capabilities
The ATS FoC conducts ASTM C1567 testing in a controlled laboratory with experienced staff and advanced equipment. We manage all aspects of the process, including mixing, sample preparation, curing, measurement, and reporting, in accordance with ASTM standards. The ATS FoC performs ASTM C1567 testing in a controlled laboratory with experienced staff and specialized equipment. We oversee all stages of the process, including mixing, sample preparation, curing, measurement, and reporting, in line with ASTM standards. Our services use the accelerated mortar-bar method to quickly assess ASR in aggregates and cementitious blends, including supplementary cementitious materials and blended cements. We provide comprehensive testing, expert analysis, actionable mitigation recommendations, and prompt turnaround to support mix design, quality control, and project compliance.
Can ASTM C1567 Testing Verify the Effectiveness of Supplementary Cementitious Materials?
ASTM C1567 testing shows how supplementary cementitious materials reduce expansion in mixes with potentially reactive aggregates. By comparing mortar bar expansions, technicians can determine if an SCM or blended system limits ASR. If a mixture expands less than a reference sample, it may offer greater ASR resistance. However, ASTM C1567 results should be considered alongside project requirements and additional data. Laboratory results may not always reflect field performance, so careful mixture design, material selection, and supplementary testing are essential for effective ASR mitigation.
