Air Plus

Air content in concrete presents a unique challenge to ready-mix operators and concrete producers across the industry. Many factors impact the amount of entrained air in a load of concrete once it leaves the plant, making incorrect air the number one reason for concrete rejection at the job site. Fritz-Pak’s air entrainer Air Plus provides drivers the ability to make small adjustments at the job site. When added to a full load of concrete, Air Plus can increase entrained air by up to 1%, making it the perfect admixture to keep on hand for standard concrete mixes. Harsh or complex concrete mixes may require a more significant adjustment, in which case Super Air Plus can provide the result you need. Both Air Plus and Super Air Plus come packaged in our signature water-soluble bags for easy use.

How Does Air Plus Improve the Concrete?

When placing concrete in colder climates, proper air content is vital for the durability of the concrete once it sets. As the concrete experiences freezing temperatures, the water the concrete absorbs freezes and expands. The air pockets created by air-entraining admixtures create adequate space for the water to expand without cracking the concrete. Without these air pockets, the concrete is likely to crack and scale. Mixes with the wrong air content will be significantly less durable than those designed with an air entrainer such as Air Plus.
