Here Is Everything One Has To Know About Expanded Clay Aggregate


The term expanded clay aggregate is known to a few professionals that strive to use it for the creation of better buildings. They are even effective for the construction of roads and highways. When one heats the clay at about 1,200 °C, they will get the lightweight expandable aggregate clay.

The heated aggregate releases various gases that further ends up making a unique structure similar to a honeycomb created by bubbles. This process enables the aggregate to turn into round potato-like shapes. The expandable clay can have different sizes depending on the utilisation of it.

The expandable clay, however, isn’t just used for construction purposes. The aquaponics and hydroponics also use these materials for retaining water and recuring roots. Moreover, due to the neutral pH level, the householders would find that the clay has less possibility to produce fungus and moulds.

The historical importance of lightweight expandable clay aggregate

The primary production of the product happened way back in Kansas City, Missouri, 1917. The manufacturers back then used the Haydite named expanded aggregate for USS Selma’s construction. It was a ship that was set to launch further in 1919. After that, the series of construction using expandable clay aggregate took place in USA and Europe both. Other countries that followed the tradition include the Middle East, Netherlands, Germany, and Denmark.

Technical specifications of the expanded clay

The surface alkalinity of the product is around 7 to 9 pH, while the Dry Thermal conductivity is around 0.09 to 0.10 W/mk. The individual manufacturers can get water absorption quality of about 18 to 20% of Sixe. Bulk density is also greater, which is around 300 to 750 kg.m3. Other factors such as compressive strength and particle size are also appropriate enough to give one high-quality clay for construction purposes.

Physical properties

Expanded clay has multiple features that can be used to select high-quality material while purchasing them in bulk. One would see that the high-quality expanded clay has the property of lower density and excellent fire resistance. It can be available in varied sizes and shapes depending on individual needs.

With high compressive strength, the product can give one the facility to be earthquake resistant. It has the ultimate level of decomposing quality, which makes it environment-friendly. It is highly resistant to water absorption. It gives effective insulation property against aspects such as thermal and sound.

Uses of expanded clay aggregate

The special clay can be used in multiple areas to provide satisfaction to all kind of clients. The first aspect is the construction of helping the individual concerning backfill, flooring, plastering, wall panel, block, insulation, PCC, and RCC, respectively. It ensures to make the house better as compared to the red bricks.

Other than that, people use this expanded clay for geotechnical purpose. It can help in aspects such as bridge applications. Fill behind retaining walls, water filtration, drainage construction, road construction, landfill, port construction, pipelines and underground conduits, railway construction, and fill on tall structures.

Surprisingly, the expanded clay can also be used for gardening purposes. One can use this particular aspect for flower beds, green roofs, landscaping, and even the flower pots. Similarly, the utilisation of expanded clay aggregate is quite effective in the agricultural community. It is quite effective with plants and ensures the farmers concerning better crops.


Expanded clay aggregate is one of the popular aspects that has helped the individuals in varieties of fields such as agriculture, gardening, construction, and geotechnology. The product leca aggregate provided by Rivashaa Eco Design Solutions Private Limited is high in demand because of the efficient physical properties, giving stronger and durable buildings.
