MAPEI Corporation announces the launch of Mapeair 154, a multi-component, air-entraining admixture developed to provide a stable, consistent air-void system throughout all phases of concrete production—from initial mixing to haul time to final discharge. Stabilized to meet industry requirements and standards, Mapeair 154 is engineered specifically for ready-mix and precast concrete applications where predictable air content is critical to long-term durability and performance.
“Maintaining a stable air-void system from the plant to the point of placement has long been a challenge for producers, especially when variables such as temperature, haul time, and materials come into play,” said Andrew Fulkerson, MAPEI Corporation’s Product Line Manager for Admixtures for Concrete. “Mapeair 154 was formulated using multiple chemistries, including natural rosin, to deliver consistent air-void percentages through every stage of the process, helping producers improve quality control and predictable performance in the field.”
Mapeair 154 is compatible with traditional Portland cements as well as Type 1L alternatives and blended systems, making it a versatile solution for today’s evolving concrete formulations. It meets or exceeds the requirements of ASTM C260 and AASHTO M154, ensuring compliance with widely recognized standards for air-entraining admixtures.
By creating uniform bubble size and spacing in hardened concrete, Mapeair 154 enhances performance in freeze/thaw environments, supporting improved durability in exposed applications. In addition, the admixture helps increase resistance to salt scaling and sulfate-related deterioration, while reducing bleeding and segregation in the concrete mix. Contractors and finishers can also benefit from improved workability, fewer surface imperfections such as “bug holes,” and smoother, more uniform finished surfaces.
“Mapeair 154 is an important addition to our admixtures portfolio, particularly as the industry continues to adopt more sustainable and alternative binder systems,” said Gerald LaPier, MAPEI Corporation’s Director of Construction Chemicals. “Its reliable performance with low-alkali cements, fly ash, and supplementary cementitious materials helps producers balance durability, workability, and long-term performance without compromising on consistency.”
Mapeair 154 also supports improved placement and finishing in challenging applications. It aids in the pumping of lean concrete mixes and is especially effective in low-slump concrete applications such as paving, making it a practical solution for a wide range of infrastructure and commercial projects.
“With Mapeair 154, MAPEI reinforces its commitment to providing advanced, performance-driven solutions for modern concrete construction,” LaPier added. “It offers the reliability our customers need to meet demanding specifications while supporting more sustainable mix designs.”
