See Descriptive Nomenclature C The descriptions provide a basis for understanding these terms as used to designate aggregate constituents.

ASTM C294:12

Work Item s – proposed revisions of this standard. Identification of the constituent materials in an aggregate may assist in characterizing its engineering properties, but identification alone cannot provide the sole basis for predicting behavior of aggregates in service. Reference to these descriptions may, however, serve to indicate or prevent gross errors in identification.

Small amounts of minerals or rocks that may occur only as contaminants or accessories in the aggregate may decisively influence its quality.

Webprint Printed and bound. Note 1-These descriptions characterize minerals and rocks as they occur in nature and do not include blast-furnace slag or lightweight aggregates that are prepared by the alteration of ast structure and composition of natural material. Blast-furnace slag is defined in Definitions C ICS Number Code Many of the materials described frequently occur in particles that do not display all the characteristics given in the descriptions, and most of these rocks grade from varieties meeting one description to varieties meeting another with all intermediate stages being found.

Identification of the constituent materials in ashm aggregate may assist in recognizing its properties, but identification alone cannot provide a basis for predicting the behavior of aggregates in service.

The descriptions provide a basis for understanding these terms as applied to concrete aggregates. When appropriate, brief observations regarding the potential effects of using the natural and artificial materials in concrete are discussed.

Aggregates of any type or combination of types may perform well or poorly in service depending upon the exposure to which the concrete is subjected, the physical and chemical properties of the matrix in which they are embedded, their physical condition at the time they are used, and other factors.

ASTM C – 12() – Standard Descriptive Nomenclature for Constituents of Concrete Aggregates

These descriptions characterize minerals and rocks as they occur in nature and blast-furnace slag or lightweight aggregates that are prepared by the c2294 of the structure and composition of natural material. Information about concrete aggregate performance in concrete has been published by ASTM.

Mineral aggregates composed of any type or combination of types of rocks and minerals may perform well or poorly in service depending upon the exposure to which they are subjected, the physical and chemical properties of the matrix in which they are embedded, c249 physical condition at the time they are used, and other factors.
