Abstract:

Appropriate curing is important for concrete to obtain the designed properties. This research was conducted to evaluate the curing ; effects of different curing materials and methods on pavement properties. At present the sprayed curing compound is a common used ; method for pavement and other concrete structure construction. Three curing compounds were selected for testing. Two different ; application rates were employed for the white-pigmented liquid curing compounds. The concrete properties of temperature, moisture ; content, conductivity, and permeability were examined at several test locations. ; It was found, in this project, that the concrete properties varied with the depth. Of the tests conducted (maturity, sorptivity, ; permeability, and conductivity), conductivity appears to be the best method to evaluate the curing effects in the field and bears potential ; for field application. The results indicated that currently approved curing materials in Iowa, when spread uniformly in a single or double ; application, provide adequate curing protection and meet the goals of the Iowa Department of Transportation. Experimental curing ; methods can be compared to this method through the use of conductivity testing to determine their application in the field.
