High-Strength Lightweight Concrete Using Leca, Silica

18/04/2012  The results obtained showed that by using Leca, a lightweight structural concrete (LWSC) can be achieved, with dry density in the range of 1,610–1,965 kg/m3 and compressive strength in the range of 34–67 MPa, based on cube specimens with 100 mm side length. Limestone significantly improved the mechanical properties of concrete whenever mixed with lightweight aggregates. This

Expanded clay aggregate - Wikipedia

Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a lightweight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln.The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure. LECA has an approximately round or potato shape due to circular movement in the kiln and is available in ...
