Trinseo (NYSE: TSE), a specialty material solutions provider, announced the release of its Report on Low Temperature Curing of Latex Modified Concrete to better understand the performance of Latex Modified Concrete (LMC) based on Trinseo’s Modifier A™ / NA Latex Binder when poured at temperatures below current specifications of 50° - 85° Fahrenheit.
The technical report includes strong evidence that LMC can be poured at lower temperatures without compromising performance. This new data provides support for state Departments of Transportation (DOTs) and LMC installers to re-examine temperature specifications and consider expanding the pouring season into the early spring and late fall, when temperatures may fall below 50°F.
“The excellent work of this study originated from conversations with our customers, said Arthas Yang, CASE Global Business Director. “Those conversations revealed a gap and industry need that Trinseo, as an experienced and dedicated supplier to the market for over 50 years, could help to solve.”
The study was executed in partnership with Concrete Strategies, who developed the LMC mix design, and GTS Consulting, who prepared the test specimens and performed the testing, which examines the testing of compressive strength, bond strength by slant shear, and ability to resist chloride ion penetration. All tests were performed in accordance with the American Society for Testing and Materials (ASTM) and American Association of State Highway and Transportation Officials (AASHTO) test designations.
To complement the full technical report, Trinseo also published a Fast Fact sheet, providing a one-page summary of the test data on compressive strength, slant shear bond strength, and chloride ion penetration resistance.
The new report builds on previous research conducted by Trinseo that focused on the extended wet cure of LMC to simulate using insulated blankets to maintain curing temperatures above the minimum DOT requirement of 50°F.
