We use a microscope to better understand your aggregates and concrete. Beton’s principal staff has more than 60 years combined experience specifying and interpreting concrete petrography for preventing, assessing and solving problems.
Petrographic test for aggregates and concrete
At Beton, we use concrete petrography as a tool to help us evaluate your materials and diagnose the problem.
Our petrographic services include:
- failure analysis of concrete through petrographic examination
- air void analysis of hardened concrete
- aggregate examination
- historic mortar evaluation
- new mortar evaluation.
At Beton, we also use our microscopes to assess mortar, characterize aggregate, and examine concrete. Some of our capabilities include:
- determining whether the concrete was made and placed and cured in accordance with the specification identifying alkali silica reaction (ASR), sulfate attack, acid attack, and other causes of failure [ASTM C856 Standard Practice for Petrographic Examination of Hardened Concrete]
- assessing whether the concrete will be durable with respect to freezing and thawing [ASTM C457 Standard Test Method for Microscopical Determination of Parameters of the Air-Void System in Hardened Concrete]
- evaluating the aggregates for potential performance in concrete [ASTM C295 Standard Guide for Petrographic Examination of Aggregates for Concrete]
- matching a historic mortar, troubleshooting a masonry problem, or designing a tuckpointing mortar compatible with the original material. We have the experience to help. [ASTM C1324 Standard Test Method for Examination and Analysis of Hardened Masonry Mortar]
Sometimes, the problem you need help with requires just petrography. Other times, concrete petrography is a tool to be used to solve your problem.
