What Is the Half-Cell Potential Test?

Sarah De Carufel June 20, 2023

Corrosion is a natural process that occurs when a structure is exposed to elements like CO2 or chloride, which can penetrate the concrete all the way to the steel reinforcement. This can have serious durability and safety consequences, which is why it is important to monitor corrosion using an accurate and trusted method. The half-cell potential test is the only corrosion monitoring technique standardized in ASTM C876 – 15: Standard Test Method for Corrosion Potentials of Uncoated Reinforcing Steel in Concrete. It is used to determine the probability of corrosion within the rebar in reinforced concrete structures. This blog dives into the specifics of concrete corrosion, the half-cell potential measurement for testing concrete corrosion, and the ways in which the data from a half-cell potential device can be interpreted.

Detect the Rate of Corrosion in Reinforced Concrete Structures in Seconds

Sarah De Carufel July 17, 2020

Corrosion is a natural process that begins when the steel rebar within reinforced concrete starts to rust. According to ACI, “corrosion occurs when the protective layer in concrete steel reinforcement is destroyed. Steel in concrete is usually protected against corrosion by the high pH of the surrounding portland-cement paste.” However, there are chemicals that can destroy the protective layer, making it susceptible to corrosion. Corrosion is very destructive to the lifespan and durability of your concrete structure. This is why it is crucial to regularly check for corrosion, which can be done with a corrosion detection sensor or a concrete corrosion test.

Field-Cured vs. Standard-Cured Cylinders: How They Affect Concrete Performance

Sarah De Carufel June 2, 2020

How do Curing Methods Affect Concrete Field Performance?ASTM C31 is the standard that defines two different concrete curing conditions, standard curing and field curing. This standard dictates the procedures for making and curing test cylinders. At the same time, it can become a problem when an engineer or purchaser argues that field-cured test cylinders must be the basis of acceptance for a project and concrete field performance.

Download Now ASTM C31 section 10.1 defines standard curing as a condition that “involves subjecting the specimens to standard temperature and humidity conditions.” According to ASTM C511, these test specimens are generally stored in curing tanks or rooms at 23.0 ± 2°C and at a relative humidity (RH) greater than 95%. The results from standard-cured concrete break tests are…

Practical Installation Locations of Wireless Concrete Maturity Sensors

Sarah De Carufel April 27, 2020

The traditional way to determine whether a concrete element is strong enough for critical construction operation is to monitor concrete strength using field cured cylinders. Once the specimens have reached the desired strength, usually 75% of the mix design strength, the project can then move forward and it becomes safe to remove forms, post tension, open roads to traffic, etc. Explore 12 Futuristic Technology Trends Solving Concrete’s Biggest Challenges.

One cylinder break result is meant to represent the entire pour and provide the decision maker with the required information to move forward and proceed with critical operations. However, this method doesn’t…

Never Have a Low Break AgainOne of the most frustrating setbacks that occurs on jobsites is low concrete breaks. It seems like they always happen at the worst time, when your schedule is already delayed and you are trying to move your project along as fast as possible. When testing your concrete for early-age strength, if the lab comes back to you with a psi/MPa that is lower than what is expected from your mix, you have very limited options moving forward, all of which require more time and money.

Importance of Initial Curing Conditions of Test Cylinders

Sarah De Carufel November 9, 2018

Why Curing Conditions for Test Cylinders is ImportantAcceptance testing for specified concrete strength is, and always has been, a necessary step in the construction industry. Nowadays, this process includes making cylinders or beams on site and bringing them to the lab for strength testing, followed by a step procedure which is outlined in ASTM C31/C31M.

Use Maturity to Determine the Allowable Variation in Temperature

Sarah De Carufel December 7, 2017

Determining the Allowable Variation in Concrete Temperature with the Maturity Method Measuring the temperature differential in mass concrete elements is essential. Because of the mass effect, the concrete core can have a really high temperature while the surface, which is greatly affected by environmental conditions, tends to be cooler. If the difference in temperature between the core and the surface is too large, it can cause internal thermal stress. If the tensile strength of the concrete is not high enough to withstand the thermal stress it can create significant cracking.
