Based on his considerable construction experience, Stephen J. Hayde thought this unusable, bloated lightweight material might make a good lightweight aggregate for concrete. Hayde was granted a patent for his method of producing lightweight aggregate in 1918. Processed aggregates today include: rotary kiln expanded shales, clays and slates ...
Expanded Clay Aggregate has been pelletised and fired in a rotary kiln at a very high temperature. As it is fired, the organic compounds in the clay burn off forcing the pellets to expand and become honeycombed while the outside surface of each granule melts and is sintered.
LECA (Lightweight Expanded Clay Aggregate) is an aggregate made by expanding clay at average 1200 C° in rotary kiln. The Yielding gases are expanded by thousands of small bubbles during this temperature and those will provide many voids and honeycombs in this aggregate by shell structure when melted material become cold.
Index Terms: Geopolymer, Light weight, LECA I. INTRODUCTION Light expanded clay aggregate (LECA) is produced in a rotary kiln at the temperature of about 1200 OC. LECA consists of small, lightweight, bloated particles of burnt clay. It is a universally accessible and an environmentfriendly, entirely natural product with a low cost and high porosity .
Light Expanded Clay Aggregate Production Line, When the raw material is clay or slurry, the production flow chart shall be consist of raw material process, mixing, granulating, insert type rotary kiln burning process, cooling process, screening and bag packing.
HANDA major in designing and manufacturing rotary kiln for the industries such as building material, mining, metallurgy, chemical industry,environmental protection, etc., and undertaking the turnkey project (project consultation, designing, equipment manufacture, commissioning and training) for lightweight aggregate system, lime calcining system, cement plant and medical waste disposal.
Lightweight expanded clay aggregate (LECA Production Line) 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.
Lightweight expanded clay aggregate (LECA), also known as expanded clay or even exclay, is a light weight aggregate made by heating clay to around 1,200 °C in a rotary kiln. The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure.

For nearly a century, ESCS (Expanded Shale, Clay and Slate) has been used successfully around the world in more than 50 different types of applications. The most notable among... is ESCS? It is a unique, ceramic, lightweight aggregate prepared by expanding select minerals in a rotary kiln at temperatures over 1000C. The production and raw material selection....
( 1m 3 requires 20packs) Expanded clay granules are made by firing selected clay in a rotary kiln at a very high temperature. As it is fired, the organic compounds in the clay vaporise forcing the pellets to expand and become honeycombed while the outside surface of each granule fuses to give a ceramic shell.
This paper discusses the unique physical characteristics of rotary kiln expanded slate lightweight aggregate for producing high performance and high strength lightweight concrete. The compressive strength, elastic modulus, splitting tensile strength, specific creep, and other properties of lightweight concrete are significantly affected by the ...
