Classification of Aggregates
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 3. The lightweight is due to the cellular or high internal porous microstructure, which gives this type of aggregate a low bulk specific gravity. The most important aspect of ...

Effect of Different Gradings of Lightweight Aggregates on the
Lightweight aggregate concrete is a material with very low density and good thermal insulation, and several types of lightweight aggregates have been used for lightweight concrete. Since the characteristics of lightweight aggregates strongly affect the properties of lightweight concrete, a proper consideration for the use of lightweight aggregate is …
Properties of lightweight aggregates produced with cold-bonding
Pelletization is a worldwide process used in producing artificial aggregates although its usage is not common in Turkey. In this study, lightweight aggregates (LWAs) were manufactured through cold-bonding pelletization of ground granulated blast furnace slag (G) and two types of fly ash with different finenesses (Fly ash A and B). Ordinary …
The Influence of Expanded Glass and Expanded Clay on Lightweight
By using lightweight aggregates and by incorporating a water reducer with cement supplementary materials (ground glass waste and silica fume), it is possible to reach 19.8 MPa of compressive strength after 28 days of hydration. This strength was influenced by a compact transition zone between the expanded glass and the hardened cement …
Lightweight Aggregate Soil Mechanics: Properties and …
The representative light weight aggregate with a dry specific gravity of l.38 will de velop a 54 percent fraction of enclosed aggregate particle ceramic solids and a remaining 46 percent pore volume (Figure 2). This leads to the illustration of the overall porosity in a bulk loose lightweight aggregate sample as shown in Figure 3.

Lightweight self-compacting concrete: A review
The strength of lightweight self-compacting concrete generally depends on the concrete mix design, type of lightweight aggregate, and its characteristics. Other factors like water/binder ratio, inclusion of pozzolan, fiber, and nanomaterials have almost similar behaviors that can be observed in conventional concrete.
Lightweight Aggregate Concrete
The less weight of light weight concrete is due to the usage of fine and course lightweight aggregate. When the complete aggregate is replaced with lightweight aggregate, the weight decreases the concrete density of by approx. 10 kilogram per cubic meter. For Example, 1 square foot of 1.5-inch thick normal concrete weighs about 18 pounds.
