Abdullahi 2 in his work noted that aggregates of different types are used in the production of concrete to attain good quality and strength concrete needs a standard mix designed go.

Aggregates happen to fall in different shapes ie round angular cubical flaky or elongated it is evident that aggregates with round angular cubical shapes are more durable and sustainable as compared to flaky and elongated ones also read shape wise classification of aggregate size wise classification of aggrega.

Effect of aggregate type on compressive strength of concrete

Any types of concrete having a density less than 1920 kgm 3 is classed as lightweight concrete various types of aggregates that are used in the manufacturing of lightweight concrete include natural materials like pumice and scoria artificial materials like expanded shales and clays and processed materials like perlite and vermiculi.

Classification of lightweight concrete there are three broad classifications of lightweight concrete based on the method employed for production 1 lightweight aggregate concrete in this method a porous lightweight aggregate of low specific gravity instead of normal aggregate of specific gravity 26 is used 2 aerated cellular foamed .

Coarse aggregate consists of either or a combination of gravel crushed gravel crushed stone aircooled blast furnace slag or crushed concrete with particles generally larger than 02 inches the maximum size of the coarse aggregates is generally in the range of 38 to 1 189 inches read more on why we use aggregates in concre.

26 different types of concrete its classification uses

Concrete is characterized by the type of aggregate or cement used by the specific qualities it manifests or by the methods used to produce it in ordinary structural concrete the character of the concrete is largely determined by a watertocement ratio the lower the water content all else being equal the stronger the concre.

Fine aggregates contain particles in the size range 75 181m to 475 mm and coarse aggregates from 475 to about 40 mm except for mass concrete which may contain particles up to 150 mm most natural mineral aggregates such as sand and gravel have a bulk density of 1520 to 1680 kgcum and produce normalweight concrete with approximately 24.

For concrete mix ratio the components are cement sand course aggregates and water different grades of concrete denotes its strength for required construction the m denotes m.
