Aggregates for Use In Concrete

Fine Aggregate Gradation • Fineness Modulus (FM) should be between 2.3 and 3.1 • FM is empirical # determined by dividing the sum of percent retained on a standard series of sieves by 100 (No. 4, 8, 16, 30, 50, 100) • Coarser fine aggregate has a higher FM Sieve Percent Passing 3/8 in 100 No. 4 95-100 No. 8 80-100 No. 16 50-85

Crushed Stone Aggregates

Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for

Concrete Basics

In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
