Shape Wise Classification of Aggregates - GharPedia

Size Wise Classification of Aggregate. The shape of aggregates is an important characteristic since it affects the workability of concrete. So we should take care about the shape of aggregate. Here we discuss the shape wise classifications of aggregates. Following are the Shape wise Classification of Aggregates: 01. Rounded Shaped Aggregate:

New Methodology for Shape Classification of Aggregates - TRID

These characteristics are form (three dimensions of coarse aggregates), angularity, and surface texture. The methodology was developed by measuring the distribution of the shape characteristics of aggregates from a wide range of sources and varying sizes. The limits for the classification groups were determined with the use of a cluster analysis.

Classification of Aggregates Based on Size

Aggregates are the most widely used products during the construction. Aggregates are the granular materials used as ingredients to make up the proportion of concrete.These materials include gravel, sand, or crushed stone mixed with water which is all added to the cement mixture to create concrete.

Particle Shape and Surface Texture - Pavement Interactive

There are several common tests used to identify and quantify aggregate particle shape and surface texture. Among the most popular are: Particle index. Percent fractured face (or coarse aggregate angularity) Fine aggregate angularity. Flat and Elongated Particles.

Aggregates - SlideShare

Jan 14, 2015 · Classification of aggregates Based on size: classified into 2 categories: • fine aggregates - those aggregates which pass through 4.75 mm sieve or aggregates with size less than 5 mm. • Coarse aggregates – those aggregates Passing through 75 mm sieve and entirely retained on 4.75 mm sieve OR those aggregates with size greater than 5 mm.


is given according to the geological classification based on mineral content, texture, mineral size and origin (sedimentary, igneous, metamorphic). For various other purposes, including those for engineering usage, rocks have been classified on the basis of their properties, such as strength, void index, degree of weathering, etc.

The Effect of Aggregate Properties on Concrete

The most common classification of aggregates on the basis of bulk specific gravity is lightweight, normal-weight, and heavyweight aggregates. In normal concrete the aggregate weighs 1,520 – 1,680 kg/m 3, but occasionally designs require either lightweight or heavyweight concrete.

What is Soil Texture? Classification System of Soil Texture ...

Textural Classification System. The US Bureau of Public Roads recommends triangular classification system for soil which is commonly called as the textural classification system. The figure- 1 below shows the textural classification system, where the three sides of the equilateral triangle represent the percentage of sand, silt and clay.

Grading of Aggregates - Aggregate Grading | The Construction ...

In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate. Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement. Mix that occupies the least volume is the densest and will produce the best results.

Effects of Aggregate Size, Shape, and Surface Texture on the ...

Aggregate size is considered to include maximum size, size range, and gradation. The earliest bituminous mixtures used the finer aggregate sizes and are generally re-ferred to as sheet mixtures. When small amounts of coarser aggregates were added to the fine aggregate -bitumen mixture, the mixtures were known as stone-filled sheet mixtures.

AGGREGATES Types Classification - Civil Engineers PK

Nov 12, 2016 · AGGREGATES Types Classification AGGREGATES. Aggregates are the inert materials mixed with binding material like cement, lime or mud in the preparation of mortar or concrete. NECESSITY OF AGGREGATES. To avoid cracking, shrinkage and to improve work-ability. To reduce the cost factor, being cheaper than the cement. To reduce heat of hydration.

5 Aggregate Specifications and Requirements

Coarse aggregates are divided into classes based on quality requirements as noted on the Classification of Aggregates table. Class AP is the highest class and is assigned to aggregates which meet the requirements for all INDOT uses. Some INDOT contracts specify type AP aggregates for use in on-grade application of portland cement concrete ...
