The Problem Isn't You. It's How It Was Explained to You.

You're at the performance exam station. The examiner hands you a thermometer and asks: is this one good enough for the test?

You read about it. But the manual puts it all in one long paragraph: accuracy, range, immersion depth. There's nothing to see, so nothing sticks.

ASTM C1064 thermometer: ±1°F (±0.5°C) over 30–120°F, designed for 3 in (75 mm) immersion.

In the book, the thermometer is a drawing: the 30–120°F range marked on the scale, ±1°F in a box, and a line 3 inches up the stem showing how deep it goes into the concrete.

Every other test works the same way: sampling from the truck, the slump cone, the air meter, the density measure, the cylinder molds. Each one has its own page.

You look, you get it, and you do it in order without going back to the manual.

COMPARE FOR YOURSELF

Same Topic, Two Ways to Study It

THIS
  • The manual: line after line
  • Field tests explained only in words
  • You walk into the exam with doubts
The sample shall be representative of the entire batch. When obtained from a revolving drum truck mixer, two or more portions shall be taken at regularly spaced intervals during discharge of the middle part of the load, and not more than 15 minutes shall elapse between the first and last portions. The portions shall then be carried to the testing location, combined, remixed with a shovel only as needed for uniformity, and shielded from sun, wind and contamination prior to testing.
FOR THIS
  • Each test in one drawing
  • The numbers in a box
  • You see it and you get it
One composite sample feeds slump, air, density and cylinders: get it right first.

One Page, One Topic, All Clear

Think of it this way:

The truck is on site, the chute is running, and you have fifteen minutes to get your sample and five to start the slump.

In the book, you open the sampling clock page and see 15 – 5 – 15 drawn as a timeline, from the first portion to the first cylinder.

C231 for dense aggregate, C173 for lightweight or porous: the choice on one page.

Same with the slump cone, the pressure meter, the density measure and the cylinder molds: each one on its own page, in the order you use it.

Concrete Field Testing Illustrated is 66 illustrated pages in 8 parts, one topic per page, with a review at the end: the clock, the numbers to memorize, the batch ticket and the field data sheet.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if my employer or my state DOT wants me certified in concrete field testing?

Yes, if your certification is built on the standard field tests: sampling (ASTM C172), temperature (C1064), slump (C143), air content (C231 and C173), density/unit weight (C138) and cylinders (C31). That's what the ACI Concrete Field Testing Technician – Grade I exam covers, and most state DOT programs use the same methods. If your DOT uses AASHTO numbers, every page shows the matching T method. Some DOTs add their own rules, so check your program's list of methods: if they're on it, they're in the book.

Where does the content come from?

From the current editions of the ASTM methods C172, C1064, C143, C231, C173, C138 and C31, plus C94 for batch tickets and the matching AASHTO methods. Everything is paraphrased and drawn, not copied.

Is this official material?

No. It's an independent illustrated study guide. It isn't published, approved or endorsed by ACI, ASTM, AASHTO or any state DOT, and it doesn't give you a certificate: certification only comes from passing the written and performance exams of your program.

Does it replace the course or the hands-on training?

No. You still need the program your employer or DOT asks for and hands-on practice with real equipment. What it adds to your course manual: every step drawn in the order you do it, the numbers in a box on each page (layers, strokes, times, measure sizes), every time limit on one page, and checklists to walk through the performance exam step by step.

Are the practice questions the ones on the exam?

No. They're written for this book, in exam style, so you can check what you know. They're not official exam questions.

When and how do I get it?

The book and the 2 bonus books come as PDFs by email, to the address you enter at checkout.

Do I have to pay every month?

No. It's a one-time payment.

Can I have it on paper?

Yes. It's a PDF you can print at home or at a print shop and take to the jobsite.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

Before You Close This Page

No more rereading that doesn't stick.

The slump cone, the air meter, the cylinders: you see them drawn, and that's it.

You walk into the exam knowing where everything is.
