Fine Aggregate: Definition, Size, Density and Properties

12/11/2017 Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone. The quality and fine aggregate density strongly influence the hardened properties of the concrete.. The concrete or mortar mixture can be made more durable, stronger and cheaper if you made the selection of fine aggregate on basis of grading zone, particle

HOW FINE AGGREGATES AFEECTS CONCRETE MIX DESIGN

Fine aggregate can be found in four different moisture conditions namely: oven-dry (OD), air-dry (AD), saturated-surface dry (SSD) and wet. Only OD and SSD correspond to a specific moisture state and can be used as reference states for calculating moisture content. Frequently, fine aggregate is in wet condition with surface moisture up to five percent. This is known as

SHAPE ANALYSIS OF FINE AGGREGATES USED FOR CONCRETE

Fine aggregate is one of the essential components in concrete and significantly influences the material properties. As parts of natures, physical characteristics of fine aggregate are highly relevant to its behaviors in concrete. The most of previous studies are mainly focused on the physical properties of coarse aggregate due to the equipment limitations. In this paper, two

A Study of Concrete Made with Fine and Coarse Aggregates

This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete. An experimental program based on two variables (proportion of fine aggregates replacement and proportion of coarse aggregates replacement) was implemented. The proportions of replacement were 0%, 50%, and 100% by mass of aggregates.

Fine aggregates consisting of natural sand and stone are classified into Zone 1 to Zone 4 on their ability to move through 600 microns. From Zone-1 to Zone-4, the zones gradually become finer. 90 to 100 percent of the fine aggregate passes 4.75 mm of IS sieve according to areas, and 0 to 15 percent passes 150 microns of IS sieve.
