Title:

Internally Sealed Concrete for Bridge Deck Protection: Final Report

Authors:

H. Celik Ozyildirim

Year:	1983

VTRC No.:	84-R4
Abstract:	This study investigated the characteristics of internally sealed concrete through tests on specimens fabricated in the laboratory to determine its properties and an installation in a bridge deck to assess the controls needed during construction and its performance over five years, the last four under traffic. Air-entrained samples prepared in the laboratory and obtained from the field during construction provided satisfactory strength and adequate freeze-thaw durability, and prevented or minimized the penetration of chlorides. However, the heat treatment of the deck led to numerous cracks which have facilitated penetration of chlorides to the level of the reinforcing steel and reduced the effectiveness of this protective system.
