 | The benefit of combining several commercial admixtures into a formulation to protect fresh concrete against freezing and promote significant strength development while the internal temperature of the concrete is below freezing was investigated. Laboratory studies developed eight potential admixture combinations for use at low temperatures. Each combination was shown in the laboratory to produce concrete that had reasonable workability; that could be entrained with air, that did not freeze until ... |

| This project was conducted to assist in predicting the effects of freeze-thaw cycling on stabilized hazardous waste material during the 1996-97 freezing season. The Raymark Superfund site in Stratford, Connecticut, is under remediation with the intent of using the area for commercial development. The site was classified as a Superfund site in 1995. The on-site soil contains asbestos, lead, PCBs, volatile organic compounds (VOCs), semi-VOCs, and solvents. These contaminants are ... |

| This project was conducted to assist in predicting the effects of freeze and thaw cycling on Tilcon common granular fill during the freezing season. This material is being used as the subbase material in the proposed pavement structure at the Raymark Superfund site in Stratford, Connecticut. Based on the initial laboratory results of the Tilcon material performed at CRREL, the amount of fines passing the no. 200 sieve was found ... |
