Expanded clay aggregate - Wikipedia. Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a light weight 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.
Manufacturing Process Of Leca Lightweight Aggregate. Types of lightweight concrete using lightweight aggregates this type is produced using lightweight aggregate such as volcanic rock or expanded clay can be produced with the use of naturally mined lightweight aggregates bulk density in the range of 880 kgm 3 or manmade lightweight aggregates like aardelite or lytag bulk density 800 …
1.1 Lightweight aggregate concrete (LWAC) There are a variety of lightweight aggregates that can be used in the production of LWAC, such as natural materials, like volcanic pumice, and the thermal-treated natural raw materials like expanded glass, clay, shale, etc. LECA is an example of expanded clay and Poraver is an example of expanded glass aggregates.

Publisher Summary. The production of lightweight aggregate concrete has been expanding to include all types ranging from no-fines concrete of low density, mainly for block production, to structural concrete with densities from 1000 to 2000 kg/m 3 and compressive strengths up to 80 MPa. This chapter explains several techniques employed for the production of lightweight aggregate concrete.
13.1. Introduction. Weight is the bane of most construction materials and this is particularly true for concrete (density ~2400 kg/m 3).Fortunately, lower density concrete can be made using lightweight aggregates that have within their mass an array of vesicules or air voids that render these aggregates of significantly lower density than normalweight aggregates.
