Methods to Increase Durability of Reactive ("D" Cracking) Coarse

The coarse aggregates used for Portland Cement concrete in southwest Iowa have exhibited a poor serviceability. This early failure is attributed to a characteristic commonly referred as "D" cracking. "D" line cracking is a discolored area of concrete caused by many fine parallel hairline cracks. "D" line cracking is primarily caused by the movement of water in and through coarse aggregate

Aggregates for Concrete University of Memphis

The fine and coarse aggregates generally occupy 60 to 75 of the concrete volume (70 to 85 by mass) and strongly influ ence the concrete s freshly mixed and hardened proper ties mixture proportions and economy. Fine aggregates (Fig. 51) generally consist of natural sand or crushed stone with most particles smaller than 5 mm ( in.).

FineAggregate Concrete Article about FineAggregate Concrete by The

FineAggregate Concrete. (or finegrained concrete) concrete produced from a mixture of fine aggregate (sand) a binder (cement) and water. Fineaggregate concrete is similar to building mortars in its composition and certain properties. It is used mainly for making thinwalled and conventional reinforcedconcrete structural components and

Concrete Mix Design for Completely Recycled Fine Aggregate by Modified

Since concrete is made of natural coarse aggregate natural fine aggregate and cementitious material recycled concrete waste is usually classified as recycled aggregate (RA) recycled coarse aggregate (RCA) or recycled fine aggregate (RFA) and recycled powder. Recycled aggregate consists of original aggregate and the adhered mortar.

Aggregate in Concrete Concrete Network

Fine aggregate should fall within gradation limits provided in ASTM C 33 Section 6. If there is a deficiency in a locally available fine aggregate concrete may benefit from the addition of air entrainment additional cement or a supplemental cementitious material (SCM) to address these shortcomings.


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.
