Featured Concrete Air Testing Meters: Why You Should Use Them

A concrete air entrainment meter is a device used in concrete testing to determine the amount of air content of fresh concrete. Introducing tiny air bubbles to the concrete mix can improve its durability and workability; you can do this by adding a small amount of air-entraining agent during the mixing process, but you must carefully measure the amount of air entrained.

An air entrainment meter consists of a pressure gauge, stainless steel pressure chamber, calibrated glass vessel, and a measuring cylinder. The process of testing involves filling the glass with a known volume of concrete, subjecting it to a vacuum, then pressurizing it to release the entrapped air. The volume of air released in then measured using the calibration cylinder, and the air content is calculated as a percentage of the total volume of the concrete.

Our concrete air meters are specifically designed for assessing and measuring the air content and entrainment in fresh concrete. With advanced features like a state-of-the-art pressure gauge, pressure chamber and air void spacing evaluation, these air entrainment meters ensure precise and dependable results. Plus, they’re designed to use fewer strokes during testing, making the process more efficient. And we offer all replacement parts, including all parts associated with the air meter cover assembly, and quality service that those in the air meter testing industry need.

All of our air meters comply with ASTM C231 standards and offer calibration adjustments for optimal accuracy. Constructed with high-quality materials like stainless steel and cast aluminum, they guarantee durability and longevity. 

The newest additions are the Concrete Pressure Air Meter Kit, complete with a rugged Gorilla Pressure Gauge, tamping rod, and plastic carrying case for ease of use, and the Super Air Meter, which has a digital gauge. For a quicker and less expensive approach to testing air entrainment in a concrete sample, our Chace Air Indicator Kit is the perfect choice.

Our starter kits also come with a plastic carrying case for easy transport and protection. Whether you’re working wit lightweight aggregates or other types of concrete, our concrete air testing meters provide all the necessary tools for accurate assessment.

Why Use a Type B Concrete Air Meter?

A Type B concrete air entrainment meter is an indispensable tool for accurately measuring the entrained air content of fresh concrete. It measures the air content of freshly-mixed content based on the pressure-to-volume relationship of Boyle's Law. With its specialized design and functionality, it enables precise assessment of air entrainment in various concrete mixes, including those containing materials that require meticulous air content control.

Type B concrete air meters play a vital role in freeze-thaw durability testing, allowing for the determination of entrained air content in concrete samples subjected to freezing and thawing cycles. This is necessary if making a structure that could come in contact with freezing water.

It may seem counterintuitive to boost the concrete air content, but the microscopic air voids are helpful for durability. Crucially, there is a difference between entrained air and entrapped air, which is why air meters are necessary to gauge the durability of fresh concrete.

By using a type B concrete air meter, you can ensure the quality and performance of the concrete. Through reliable results, it’s easy to evaluate the durability of the air-entrained concrete and adjust as necessary. 

Benefits of Entrained Air Tests 

Concrete air meters offer a range of benefits for assessing the air content in concrete. By accurately measuring the air entrainment, these air meters ensure the desired entrainment is achieved, resulting in enhanced durability during freeze-thaw conditions.

These tests also provide valuable insights into the overall quality of the concrete, ensuring it meets the required specifications and standards. Concrete air meters enable precise monitoring of air bubbles and void spacing, contributing to improved workability, finishing, and construction quality.

Non-air-entrained concrete naturally contains some moisture levels; when temperatures drop to freezing, the moisture content expands. Without adequate room, the surface can rupture and crack, resulting in surface scaling. The billions of air bubbles created with entrainment act as reservoirs to maintain the expanding moisture. As a result, having a concrete air meter on hand to check the air content of fresh concrete can be the difference between a stunning building and a crumbling structure.

Importance of Entrainment Measurements

The importance of using concrete air meters to measure entrainment cannot be overstated. They play a crucial role in assessing air voids within fresh concrete, ensuring enhanced durability.

When working with concrete air entrainment meter, it’s vital to use an air entrainment meter or testing equipment to ensure you’re correctly treating the admixture. If not done correctly, problems can arise that compromise the strength of the concrete. When it comes to proper concrete air entrainment meter, the spacing and size of the bubbles are essential. The bubbles must be spaced no more than .01 inches apart throughout the admixture.

Without proper spacing, the durability of the concrete mixture is compromised, which could mean you have to start from scratch. Air entrainment testing equipment gives you the most accurate overview of the air content, and top-quality products are the best way to get precise results. 

Our air meters offer convenience and ease of use, with reliable test pressure gauge for accurate measurements. Whether you need a starter kit  that is supplied complete with the air entrainment meter all the items needed for the air entrainment tests, or replacement parts, we have it all.

Products like our American Cube Mold ACM-6 Concrete Air Entrainment Kit with Rubber Mallet come complete with everything you need to measure your admixture, including an tamping rod. We also carry products like the American Cube Mold ACM-6A Concreate Air Entrainment Meter (Type B), which offers a less expensive option for efficient testing. We also sell the new air entrainment meter digital pressure gauge called the Super Air Meter.
