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.

W hat Is Lightweight Concrete?. Lightweight concrete is a mixture made with lightweight coarse aggregates such as shale, clay, or slate, which give it its characteristic low density. Structural lightweight concrete has an in-place density of 90 to 115 lb/ft³, whereas the density of regular weight concrete ranges from 140 to 150 lb/ft³.
The impact of different types of lightweight aggregate and other influential factors on workability, strength, and durability have been carefully discussed in this study which shows it is possible to develop lightweight self-compacting concrete even below the 1000 kg/m 3 density. In addition, lightweight self-compacting concrete shows excellent ...

Concrete is the most widely used composite artificial construction material in the world. Coarse aggregate constitutes an integral part of concrete for attaining its crushing strength.Even though crushed stones are widely used as coarse aggregate, continuous quarrying of rocks leads to massive environmental issues such as land …
4. Lightweight SCC over normal SCC. Normal or lightweight SCC are new generations of concretes in which the aggregate (lightweight or normal weight aggregate) is encased/enclosed in a very flowable paste [41].. Each can flow under its weight without segregating and bleeding [42], [43].In addition, normal and lightweight SCC include …
BASIC CHARACTERS Lightweight concrete, similar to normal weight concrete, is a mixture of water, Portland cement or Ordinary Portland Cement (OPC), and aggregate. Lightweight aggregate concrete uses a variety of aggregates with lower density than normal weight concrete. The combination of strength, weather resistance, …
Lightweight ConcreteLightweight Aggregate Concrete. Definitions: Lightweight concrete has a maximum density of 1900 kg/m3 and is achieved by using low-density aggregates. Intermediate-density concretes, where part or all the normal-density coarse aggregates are replaced with structural-grade low-density aggregates, have …
