Lightweight aggregates As mentioned in the body of this paper lightweight concrete contains aggregate that is natural or synthetic which weighs less than 1100 kg/m lightweight is due to the cellular or high internal porous microstructure which gives this type of aggregate a low bulk specific gravity
· Coarse Aggregates in Construction Types and Uses Aggregates are inert granular materials that provide volume to the concrete In the construction industry they have a different basis for classification One crucial basis is their grain size They are grouped as fine and coarse aggregates as per their particle size This article is a short guide on the coarse
Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage Aggregates occupy 70 to 80 % of total volume of concrete So we can say that one should know definitely about the aggregates in depth to study more about concrete Classification of Aggregates as per Size and Shape Aggregates are classified based on so

· Solid concrete blocks are usually heavier than hollow blocks but they can be less expensive Types of Hollow Concrete Blocks Hollow concrete blocks come in a variety of sizes such as 100 mm x 200 mm x 400 mm 150 mm x 200 mm x 400 mm and 200 mm x 200 mm x 400 mm These blocks are most commonly gray but can also be found in different colors
· 1 Standard exposed aggregate Aggregate is mixed into the concrete batch itself whereas the surface aggregate will be a random placement of any of the type of aggregate that were originally mixed 2 Topping aggregate Another way of having a bit more control over the surface aggregate is by using a topping system
ADVERTISEMENTS In this article we will discuss about the natural and artificial types of light weight aggregates 1 Natural Aggregate They are not of uniform quality and not found in many countries As such they are not used universally for making light weight concrete Out of all the natural light weight aggregate only pumice is []
· Aggregate is a granular material such as sand gravel crushed stone crushed hydraulic cement concrete or iron blast furnace slag used with a hydraulic cementing medium to produce either concrete or mortar Types of aggregates include Coarse aggregate and fine aggregate The aggregate of each type is further sub divided into many types and
The Recycled aggregates properties may be different accordingly types of concrete because the parent concrete was designed for its purposes such as permeable durable and high strength concrete Aggregate recycling is a simple process there is no complex method involved The recycling method includes breaking removing and crushing existing concrete into a material
· Aggregate is a landscaping term that s used to describe coarse to medium grain material The most common types of aggregate that are used in landscaping include crushed stone gravel sand and fill Varying in material and stone size each type can have its own purpose when it comes to landscaping projects
Aggregate in concrete should chemically stable or inert Aggregates in the concrete are responsible for unit weight elastic modulus and thermal properties of the concrete Aggregates can be classified on the basis of their size shape surface moisture surface texture and bulk density of aggregates Lightweight Aggregates The aggregates having a bulk density of
Concrete Aggregates Granular material either natural/processed from deposits of sand gravel or rock Normally sized as coarse aggregate or fine aggregate Coarse Aggregate is normally greater than 5mm Fine Aggregate is aggregate less than 5mm Can be a single sized material typically 20mm 14mm 10mm or 7mm or a graded aggregate consisting
Aggregates are used for a variety of purposes Each purpose requires a specific aggregate type and specific properties of the aggregate In general aggregates are naturally occurring relatively inert materials formed by various geologic processes The geologic process of formation imparts some of the properties to the aggregate that make it more or less useful
Aggregates are mainly used to produce concrete which is produced by mixing a certain amount of cement aggregates coarse fine aggregates and water In this article we will discuss different types of aggregates used in construction and their classification
