Title: Qualifications of Different Kinds of Natural Stone for Concrete Aggregate
Author(s): G.F. Loughlin
Publication: Journal Proceedings
Appears on pages(s): 319-351
Abstract:Concrete has not always given complete satisfaction and its imperfections have been attributed to different causes. Accumulation of evidence has given the impression that one of the causes that has not been fully appreciated is the poor quality of aggregate that has too often been used in concrete. The usual physical tests are adequate for the determination of some of the qualities of aggregate, but do not indicate certain other qualities, particularly resistance to prolonged weathering. It is the object of this paper, therefore, to supplement the usual test data by calling attention to the fundamental physical and chemical properties of natural stone and to the consequent behavior of different kinds of stone when used as concrete aggregate. The writer's viewpoint is that of the geologist interested in the correct use of stone but inexperienced in the mixing and handling of concrete. A through appreciation of the use of natural stone in concrete obviously calls for close co-operation of the geologist with construction engineers.
