of aggregate are expanded clay, shale, perlite, vermiculite and slate. The third type is industrial by-product such as expanded slag, fly ash, and cinder[1]. Expanded clay is a powdery building material with good thermal insulation properties and resistance to the external impacts. It is obtained by feeding clay .

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.

Expanded or expandable clay aggregate is a commonly used hydroponic grow medium. It is a lightweight aggregate that is heated in a kiln oven to a temperature of 2,910 degrees Fahrenheit (1,200 degrees Celsius). Once the aggregate is heated, it releases gases, which create small bubbles that make a honeycomb-like structure inside of the aggregate.

The main substance of ECA block is Expanded Clay Aggregate which is formed at 1200C. Read More. High Resistance to Water Absorption.

Benefits of expanded clay balls. The expanded clay aggregate balls are made of clay heated at one specific high degree temperature in a rotary kiln. The reason for this process is to make it durable for the use of it in construction as well as several other fields.

While feedstock preparation is essential in producing expanded clay aggregates, the key process behind expanded clay aggregates is a thermal treatment. This thermal treatment is where the expanded clay aggregate name is derived from, as it is used to physically expand the clay particles.

Lightweight expanded clay aggregates (LECA) were used to produce LWSCC. • Methodology set by Nepomuceno et al. for self-compacting concrete (SCC) was tested. • Methodology for SCC mix design successfully produced LWSCC using proper correlations. • Correlations to support application of the mix design method for LWSCC were presented.

Expanded clay is a lightweight aggregate manufactured from naturally occurring clay. It is non-toxic, disease free, chemically inert and has a neutral pH. It is used for a variety of applications including; a construction aggregate in lightweight concrete castings, floors and panels and as a loose lightweight fill. It is also used extensively ...

While Leca® lightweight aggregate is a simple product, our solutions are innovative. Alone, it is one single expanded clay pellet, but combining the pellets into an aggregate, possibilities become numerous – whether it is laying the foundation for construction, building roads and .

Expanded Clay Aggregate (ECA) material in blocks and panels is significantly lighter than its available alternatives which subsequently allows the building works to progress faster than some alternatives. Fire Resistance. Expanded Clay Aggregate (ECA) is a round pellet structure produced by firing natural clay at temperature of 1200°C.

Internal Curing (IC) for cement is a practical way of supplying additional water throughout the concrete mixture. In other words, achieving better hydration and less waste of valuable cement. This is done by consuming absorbed water in Light Expanded Clay Aggregate (LECA) which is replacing some of the conventional aggregates in the mixture.

Canna Aqua Clay Pebbles consist of different components that together form an optimum, heterogeneous structure that is ideal for root development. Canna Aqua Clay Pebbles are also known as "Hydroton", "LECA" (Light Expanded Clay Aggregate), or "Clay Pellets".

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.

Using pre-wetted expanded clay aggregate with same cement mortar resulted in the density of 1900 kg/m3 with a compressive strength up to 70.2 MPa. x Although having similar mechanical properties as the waste plastic aggregate, higher porosity pre-wetted expanded clay aggregate creates optimal conditions for cement hydration, which results two ...

Expanded clay aggregates are porous ceramic products with a uniform pore structure of fine, closed cells and with a densely sintered, firm external skin. It is manufactured in rotary kilns from raw materials containing clay minerals.
