SCP Meeting at ASTM Toronto 

Please join us for the Society of Concrete Petrographers meeting on Tuesday evening, June 13, in Toronto in conjunction with the ASTM meeting. The meeting will be held in the Linden Room, located on the mezzanine level of the hotel. Depending on the number of attendees, we will either convene for a review of business matters and a presentation by Laura Powers on Shotcrete and Gunite: Applications and Analysis, or move to the bar for an informal gathering. Laura's presentation will discuss the invention and development of shotcrete / gunite and describe some of the important applications. She will compare the normal features of shotcrete produced by the dry-mix process and wet-mix process and discuss the petrographic approach to assess the performance of the materials.

39th ICMA Conference Toronto, April 10-13, 2017

ICMA will hold its 39th Conference in the beautiful City of Toronto, Ontario, Canada. Toronto is Canada’s largest city with a population of almost 5.6 million and is the fifth largest city in North America. Toronto is the world’s fourth most livable city. Toronto ranks second as the world’s most business competitive global city. Toronto sits on the northwest shore of Lake Ontario. The meeting place is at Crowne Plaza Toronto Airport, 33 Carlson Ct., Toronto, Ontario, Canada scheduled on April 10 – 13, 2017. The technical program includes papers that are good blend of practical applications, new techniques and novel approaches and the latest research efforts in the field of microscopic evaluation of portland cement and related materials. The Workshop Committee will prepare Panel Discussions and Workshops that are timely and interesting to the participants. The Spouse and Guest Committee has programs and tours to the many beautiful and interesting sites of Toronto, Ontario Area for the spouses and guests accompanying the attendees. Please be informed that the deadline date for submission of abstracts will be on or before December 15, 2016. Please visit the ICMA website ( for more information about the conference.

SCP Meeting - Tuesday, June 28 in Chicago 

Please join us for the Society of Concrete Petrographers meeting on Tuesday at 6:30 in Chicago in conjunction with the ASTM meeting. The meeting will be held in the Los Angeles/Miami Room – 5th Flooor at the Chicago Marriott Downtown.

Following a brief business meeting, we will have a discussion on the effect of deicing salts on freeze/thaw damage in concrete with particular emphasis on the formation of Calcium Oxychloride due to the use of Calcium Chloride and Magnesium Chloride deicing salts. In recent years significant amounts of research has been performed on this topic, however, much of this research is based on laboratory studies. Evidence of distress related to calcium oxychloride can be very difficult to confirm in petrographic work performed on cores removed from the field. ACI 201 is currently working on a TechNote on the topic of joint deterioration due to deicing salts and the formation of calcium oxychloride.

Karl Peterson from the University of Toronto will give a brief presentation on his research on distress related to the formation of calcium oxychloride.


Petrographer Job Opening

Experienced Petrographer

Wiss, Janney, Elstner Associates, Inc. (WJE) is seeking an experienced (10 plus years) Petrographer to work out of our Janney Technical Center laboratory in Northbrook, IL. The successful candidate will have responsibility for various types of microscopical examination of construction materials, coordinating testing, interpreting results, consulting with staff scientists, engineers and architects, and interacting with clients.  Materials routinely analyzed in our facility include concrete, dimension stone, stucco, mortar, brick, terra cotta, grout, aggregates, and other materials in modern and historic structures. Candidates must have excellent verbal and written communication skills, and should be self-starters, and able to work with a great team of professionals.

At WJE our history has been built upon the principle that delivering better solutions requires a better understanding of the problem. Our team of recognized petrographers and scientists provide consulting and testing services that are crucial to developing this comprehensive understanding. Our full range of services in petrography, microscopy, analytical chemistry, organic and inorganic chemistry, and physical testing of materials puts our capabilities at the forefront of the profession. The combination of our construction materials knowledge with our engineering and architectural capabilities uniquely positions WJE to deliver innovative yet sound solutions to problems. Using state-of-the-art evaluation methods, many of which were pioneered by WJE, our materials scientists have solved thousands of construction materials problems answering such questions as, why did it fail? how long will it last? and how do I fix it?


  • Degree in Geology, Materials Science/Engineering, Geological Engineering, or a related field with substantial coursework in mineralogy, petrology, and geochemistry. Master’s degree preferred.
  • Ten or more years of petrography experience examining construction materials. 
  • Substantial familiarity with traditional petrographic microscopy: thin section analysis; immersion mount analysis; hand sample analysis with a stereomicroscope; point-count and modal analysis; and preparation of thin sections, polished sections, lapped hand samples, etc. Knowledge of the operation of the polarized-light microscope is essential.
  • Experience in polished and fracture surface analysis with SEM/EDS 
  • Basic knowledge of complementary material characterization techniques such as x-ray diffraction, x-ray fluorescence, and atomic absorption. 
  • Solid skills in material and mineral identification using polarized-light microscopy, and in the description and classification of igneous, metamorphic, and sedimentary rocks, their mineral assemblages, and the common types of alteration
  • Ability to interpret results of such examinations as they apply to materials characterization, degradation mechanisms, potential future performance, specification compliance and construction quality.
  • Ability to write clear, concise, informative reports.
  • Excellent verbal communications and client relationship skills.

Key Competencies:

  • Energy and Enthusiasm - Consistently maintains high levels of activity and productivity.
  • Attention to Detail - Careful and quality oriented.
  • Communication - Clearly conveys information, both verbally and written.
  • Assumes Responsibility - Self-starter, willing to interact as a team player, and take independent initiative. Works proactively in solving problems; makes self available and takes action beyond normal responsibilities.
  • Interest in WJE work - Has strong desire to collaborate with WJE engineers, architects, and scientists to analyze construction materials and solve problems within the construction industry.
