Title:

Evaluation of Shield–Forming Curing for Concrete Pavement

Accession Number:

01373781

Record Type:

Component

Abstract:

The main cause of early shrinkage is the loss of moisture which produces a reduction in the absolute volume of solids and liquids in paste resulting from cement hydration in fresh concrete. Additional early shrinkage in fresh concrete takes place due to the macroscopic volume reduction associated with the loss of water from the capillary pores resulting from the cement hydration. Shield forming curing method used in this study provided an adequate approach to uniformly cover the entire concrete surface. The shield forming curing consists of lithium silicate (Lithium Cure) and Sodium Silicate Cure. The film layers produced by the silicate solutions prevented the loss of mixing water from the surface of concrete, and minimized the non-uniform concrete shrinkage in concrete slabs.
