Title: Concrete Bridge Decks: Lightweight
Aggregate Concrete Subject to Severe
Author(s): T. A. Holm, T. W. Bremner and J. B. Newman
Publication: Concrete International
Appears on pages(s): 49-54
Keywords: bond (paste to aggregate); bridge decks;
concrete durability; corrosion; cracking (fracturing); ex-posure;
lightweight aggregate concretes; lightweight
aggregates; marine atmospheres; microcracking; mi-crostructure;
permeability; ships; weathering.
Abstract:The influence of the internal structure of lightweight aggregate on the physical and durability characteristics of concretes used in severe weathering applications is examined. Scanning electron microscopy studies on cores from weathered surfaces of mature structures are reported and compared with field experience. Cracking response and other mechanical properties are related to the characteristics of the lightweight aggregate.
