About Expanded Clay Aggregate
We "Apex Green" supply Expanded Clay Aggregate (ECA) OR Leca Clay balls for Hydroponics purpose. We have best quality clay balls available in different sizes.The particles formedare rounded in shape and generally range in size from 0-30mm;these are processed to the required grading, depending on the final use. ECA is an extremely lightweight, strong and thermally insulating material.

Versatile ApplicationsExpanded Clay Aggregate suits a range of applications including hydroponics, horticulture, landscaping, concrete production, and drainage systems. Its lightweight nature and stability make it highly adaptable for both commercial and residential projects, ensuring consistent performance across diverse environments.
Superior Performance CharacteristicsWith a high compressive strength, low thermal conductivity, and excellent fire resistance, ECA stands out as a reliable construction and growing medium. Its neutral pH, high porosity, and chemical inertness provide a healthy and safe solution for plant roots as well as building structures exposed to various stresses.
Environmentally Friendly and DurableManufactured from natural clay, ECA is expanded and kiln-fired, resulting in a recyclable, reusable product. It does not degrade over time, maintaining its shape and properties, which contributes to sustainable construction and gardening practices with minimal environmental impact.
FAQ's of Expanded Clay Aggregate:
Q: How is Expanded Clay Aggregate manufactured?
A: Expanded Clay Aggregate is produced by heating natural clay at high temperatures in a rotary kiln. This process causes the clay to expand into lightweight, porous, and round granules with high strength and durability.
Q: What benefits does ECA provide in hydroponics and horticulture?
A: ECA offers excellent aeration and moisture retention due to its high porosity, supporting healthy root development. Its chemically inert nature ensures a stable pH, preventing nutrient imbalances and promoting robust plant growth.
Q: Where can Expanded Clay Aggregate be used effectively?
A: ECA is versatile and can be used in hydroponics, horticulture, landscaping, drainage systems, and as an aggregate in lightweight concrete. Its lightweight and robust properties make it suitable for both indoor and outdoor uses.
Q: When should I choose ECA over traditional aggregates?
A: Choose ECA when you need a lightweight, fire-resistant, and durable aggregate, especially in environments requiring thermal insulation, high compressive strength, or where root health is important, such as in hydroponics or green roofs.
Q: What is the typical water absorption range for Expanded Clay Aggregate?
A: ECA absorbs water at a rate of 15% to 30%, depending on the grade. This characteristic enhances moisture availability for plants and improves the performance of drainage and concrete applications.
Q: How does the chemical composition of ECA contribute to its properties?
A: Its main components-SiO2, Al2O3, and Fe2O3-provide chemical stability, non-toxicity, and resistance to degradation, ensuring long-term durability and safety across all recommended applications.
Q: What packaging options are available for ECA in India?
A: Expanded Clay Aggregate is available from manufacturers, distributors, exporters, suppliers, and traders in India, and can be delivered either in standard bags or in bulk packaging according to project needs.
