Findings from a new technical study released by Trinseo last fall have recently been published in the January issue of Roads & Bridges Magazine. The article titled “Low Temperature Curing, Can we Extend the Pour Season for Latex Modified Concrete?” was authored by Chuck Fifelski, Senior Technical Service Specialist, Trinseo.
The article discusses the data revealed by the study showing strong evidence that Latex Modified Concrete (LMC) can be poured and cured at lower temperatures than current Departments of Transportation (DOTS) specifications without compromising performance. With all tests performed following the American Society for Testing and Materials (ASTM) and American Association of State Highway and Transportation Officials (AASHTO) test designations, the new report provides strong support for DOTs and installers to re-examine temperature specifications and consider expanding the pouring season into the early spring and late fall when ambient temperatures may fall below 50°F.
“Study results showed that LMC cured under low temperature conditions and developed exceptional mechanical properties as shown in compressive strength and bond strength performance. Additionally, chloride ion penetration resistance improved over time and is not impacted by low temperature curing.
Knowing that LMX can be poured at lower temperatures without compromising performance, installers and DOTs alike should consider extending their pour season, and DOTs could benefit from an extended installation window to complete infrastructure projects.”
