Concrete Coring for Petrographic Analysis

Petrographic Analysis of Concrete and Aggregates

Petrographic Analysis is an essential technique to examine the mineralogical, chemical, and physical properties of concrete and aggregate materials. At Atlantic Testing Laboratories (ATL), we provide expert petrography services that support construction quality control, material qualification, forensic investigations, and failure analysis. Our evaluations help clients understand the behavior of concrete and aggregates, identify potential issues, and ensure the durability of materials used in construction projects. With more than 50 years of experience in the industry, ATL is trusted by contractors, engineers, and construction teams to provide high-quality petrographic analysis services. Our laboratory utilizes advanced microscopy and imaging tools, including Scanning Electron Microscopes (SEM) and X-ray Diffraction (XRD), to offer detailed insights into the microstructure of concrete and aggregates. This helps us assess material quality, performance, and potential failure mechanisms, making our services indispensable for new construction and forensic analysis of material degradation.

Comprehensive Petrography Services at ATL

ATL’s petrographic analysis follows rigorous industry standards, including ASTM C856, C457, and C295, ensuring the highest level of accuracy and compliance for our clients. Our expert geologists conduct comprehensive evaluations to provide essential data for material assessments and failure investigations.

Our Petrographic Services Include:

ASTM C856 – Petrographic analysis of hardened concrete: Examines the composition, properties, and performance of concrete to assess durability, quality, and causes of material failure.
ASTM C457 – Air-void system analysis: Evaluates the air-void system in hardened concrete, an essential factor for assessing freeze-thaw durability.
ASTM C295 – Petrographic examination of aggregates: Assesses the suitability of aggregates for concrete mixtures and identifies potential issues such as alkali-silica reactivity.
SEM and XRD Analysis – Detailed microstructural analysis using Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) to identify mineral compositions, crystallography, and other material characteristics.
Assay and Trace Element Analysis – Identifies the elemental composition of concrete, rock, and mineral samples to assess their quality and potential impact on performance.

These services are integral to understanding how materials will behave over time, whether you’re evaluating freeze-thaw durability, identifying alkali-silica reactivity (ASR), or conducting forensic investigations into concrete failures.
