Objectives

This study will develop an antifreeze admixture conforming to existing industry standards. The proposed work will adapt recently developed knowledge about off-the-shelf admixtures to the specific conditions of highway construction. The admixture will protect concrete to 23°F or lower and allow concrete to gain appreciable strength while at that temperature.

Comments

Ongoing. The testing of various admixtures is moving forward. Please see the above link for progress reports. CRREL contact is Chuck Korhonen (603/646-4438) 2/19/02.

Subjects: Materials and Construction Pavement Design, Management, and Performance
