Petrographic Analysis Reference Number ISRM Material. Rock. Test Property. Mineralogy and Rock Description. Description of Test. The petrographic analysis of rocks for engineering purposes includes the microscopic examination of a polished thin section of rock.

Petrographic testing

The samples examined may be taken from concrete constructions, that is, all sorts of objects, units, or structures that have been built of hydraulic cement concrete. 2019-04-12 · Testing the integrity of concrete and other concrete products is referred to as petrographic testing. A full petrographic testing procedure is composed of two separate tests: the petrographic analysis and the air void analysis. Petrographic analysis testing is performed on samples of hardened concrete or concrete products from construction sites, or existing concrete that has been exposed to natural elements. Petrographic Analysis of Hardened Concrete - PELCON Petrographic Analysis of Hardened Concrete Pelcon has a long experience in preparing and analyzing fluorescence impregnated thin and plane sections.

The petrographic examination is able to test the alkali-silica reactivity (ASR) of aggregates.

This technique examines and evaluates the optical properties and microstructural characteristics of the materials. Petrographic analysis for concrete begins by accepting an aggregate for use in concrete (ASTM C295). Petrographic Analysis. Petrography is the detailed study and classification of rocks and minerals.

It is the responsibility of the Laboratories to train and maintain competent testing personnel and ensure that all LS-609 client tests are done by certified analysts. Petrographic testing can be used for any type of project, but it is typically used when the client is having some type of issue with their concrete.
