May 24, 2017· LWAC is the popular type of lightweight concrete, in which lightweight aggregates are used. The lightweight aggregates are relatively new materials. These have a unit weight up to 12kN/m3. The LWA can be either natural or artificial or manufactured. The natural aggregates include volcanic cinder, dolomite or pumice.
Nov 05, 2010· The Expanded Clay Lightweight Aggregate (LWA) is used to create safer pavement and asphalt with its rough texture, system of non-connected internal voids, and skid resistance.
Usually the density of concrete made from expanded shale and clay aggregate varies from 1400 to 1800 kg/m 3. The strength of concrete made from expanded clay or shale aggregate is higher than concrete made with other light weight aggregates. iv. Perlite: It is a glassy volcanic rock found in America, Italy and Ulster etc.
