Aggregates for Concrete

concrete. A typical consensus specification for fine and coarse aggregate for concrete is ASTM C 33. Synthetic aggregates may be either byproducts of an industrial process, in the case of blast-furnace slag, or products of processes developed to manufacture aggregates with special properties, as in the case of expanded clay, shale, or slate used for lightweight aggregates. Some lightweight ...

5 Aggregate Specifications and Requirements

Section 904.02 states that fine aggregate shall consist of natural sand or manufactured sand produced by crushing limestone, dolomite, steel furnace slag, air cooled blast furnace slag, or wet bottom boiler slag. At the time of use these materials shall be free from lumps or crusts of hardened or frozen materials. The detection of lumps or crusts of hardened or frozen materials is possible only through visual inspection.

Aggregates for Concrete - Civil Engineering

The 13 standard sieves for coarse aggregate have openings ranging from 1.18 mm to 100 mm (0.046 in. to 4 in.). Tolerances for the dimensions of open-ings in sieves are listed in ASTM E 11 (AASHTO M 92). Size numbers (grading sizes) for coarse aggregates apply to the amounts of aggregate (by mass) in percent-ages that pass through an assortment of sieves (Fig. 5-5). For highway construction ...

Aggregate is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete - aggregate properties are, therefore, critical for quality hot-mix asphalt or concrete. Typically, hot-mix asphalt mixtures consist of 50 percent coarse ...

HOW FINE AGGREGATES AFEECTS CONCRETE MIX DESIGN

Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus, moisture content, specific gravity, and silt content affect the mix proportions of concrete. Fineness modulus specifies how much fine aggregate is required in a given mix design.
