A mass concrete placement needs a thermal control plan. We’ll help you meet the requirements—usually without cooling tubes.
We know the science behind your concrete. Whether you need a thermal control plan, a concrete specification, or an expert witness, we can help.More About Us
If your concrete fails, we investigate what went wrong, who’s responsible, and how to remedy it.
We’ll help you achieve the required concrete service life in its exposure conditions.
We can help you turn waste glass and other byproducts into concrete with a lower carbon footprint.
Petrography can tell you a lot about your concrete, aggregate, or masonry—whether its current condition or future performance.
Beton performs concrete testing in the lab and the field.
What are concrete exposure classes?
The service environment for a concrete structure or pavement may pose challenges to its durability. ACI 318 categorizes them as freeze-thaw (F), sulfate (S), water (W), and corrosion (C). Each category has numerical rankings for severity. For example, an exposure class of S3 indicates the severest exposure to sulfates, such as for a concrete foundation in soil with a high sulfate concentration. The concrete may be subjected to more than one type of exposure. For example, a parking garage slab may experience freezing and thawing in the presence of water and deicing salts. This is both an F3 and a C3 exposure, so you need to design for both conditions.
