If testing of hardened concrete is to be used to deter-mine compliance with codes or contract documents, ASTM C 823 states that not less than five samples should be taken from each category of concrete for each test. Thus conclusions based on a sample size of less than five don’t meet that criterion.

One of the largest and most qualified petrographic analysis teams in the world An in-house laboratory that can test material failures and resolve them using a variety of engineering solutions Proven knowledge with Fourier Transform Infrared Spectrometry (FTIR), X-ray Fluorescence (XRF) and X-ray diffraction for identifying components in cementitious materials and admixtures Petrographic analysis is carried out first based on core data, geochemical analysis, and thin section information. This is followed by the identification and classification of volcanic rocks using the “component + texture + genesis” scheme. PETROGRAPHIC ANALYSIS Advance Testing leads the industry through innovation and excellence, often at the forefront of developments and new procedures. Our state-of-the-art petrographic laboratory is one such example of this; capable of analyzing carefully prepared specimens of concrete and/or aggregate to determine its characteristics. Petrography is also the only accepted method to determine if concrete is undergoing progressive deterioration from mechanisms such as alkali-silica reaction, sulfate attack, chemical attack, corrosion, early freezing, freeze-thaw damage, and more.

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. For example, Fenagh once had a case with a precast panel that required Petrographic Testing. A precast panel is a slab that is poured somewhere else then is moved onto the site and positioned in place.

Petrography is the detailed study and classification of rocks and minerals. Analysis is undertaken by the macroscopic description of hand specimen size samples, followed by a detailed microscopic examination of a thin section of the material in question.

Petrography is a branch of geology that is applied to concrete and concrete raw materials. This technique examines and evaluates the optical properties and microstructural characteristics of the materials.

Petrographic analysis collects data In order to establish the 'natural' origin of pyramid stones, CMC provided detailed petrographic examinations of casing stones from the Great Pyramid of Giza. Description of Test. The petrographic analysis of rocks for engineering purposes includes the microscopic examination of a polished thin section of rock. It is used American Petrographic Services provides Forensic analysis on concrete, concrete constituents and other building Link to American Engineering Testing, Inc. At C3S Inc, petrographic examination is a quick and relatively inexpensive test which can determine numerous characteristics of hardened concrete in order to Examination of rock and mineral samples in the pursuit of mineralogy and geological knowledge is an extremely common but nuanced discipline.

This combination of techniques affords an opportunity to determine the composition of the type of mortar (M, N, S and O) as described in ASTM C270, Specification for Mortar for Unit Masonry.

Petrographic testing is the use of microscopes to examine samples of rock or concrete to determine their mineralogical and chemical characteristics. Samples for petrographic examination can be taken from lump samples or cores. They are impregnated with resin.

A petrographic based Weathering Index Analysis (WIA), as developed by Wagner (1998), can be used to quantify and qualify the degree of weathering (oxidation) in coals and coal blends. In a case study reported by Wagner (2002), a link was determined between inertinite-rich coals with unusually high inherent moisture content and an increase in fine particulate carryover into the raw syngas stream.
