Lecture 4. Aggregates

The variability in aggregates' density can be used to classify aggregates of widely different unit weights, shown in Table 1. The most common classification of aggregates on the basis of bulk specific gravity is lightweight, normal-weight, and heavyweight aggregates. Table 1. Unit weight classification of aggregates Category Bulk specific gravity

WHAT YOU SHOULD KNOW ABOUT AGGREGATES

Normal-weight aggregates So-called norm a l - w eight aggregates produce concre t e that weighs around 150 pounds per cubic foot, or 2 tons per cubic yard. The rocks which comprise most norm a l - weight aggregates are limestone, quartz, quart z i t e, sand-s t o n e, dolomite, trap rock, and gra n i t e, or combinations t h e r eof.

Normal-Weight Aggregates

Used in most concrete construction, normal-weight aggregates are obtained by draining riverbeds or mining and crunching formational material. Concrete made with normal-weight fine and coarse aggregates generally weights about 144 lb / ft3.
