FAQ's of Leca Application LLP:


Q: How is LECA typically used in construction and horticulture?

A: LECA is used in construction as a lightweight aggregate in concrete, enhancing insulation and reducing structural weight. In horticulture, it functions as a soil conditioner and drainage layer, promoting root aeration and moisture retention for healthy plant growth.

Q: What benefits does LECA offer compared to traditional aggregates?

A: LECA offers significant advantages, including excellent fire resistance, high durability, lightweight properties, and superior thermal insulation. Its eco-friendly composition makes it safer for the environment, and it won't decompose or leach toxins over time.

Q: Where can LECA be applied outside of building projects?

A: Beyond construction, LECA suits water filtration, geotechnical fills, hydroponic systems, and landscaping. Its ability to maintain structural integrity and filter contaminants makes it valuable in civil engineering and environmental projects.

Q: What is the process behind manufacturing LECA?

A: LECA is produced by heating natural clay to 1200-1250C in a rotary kiln, causing it to expand and form hard, round pellets with a porous core. This process grants LECA its unique lightweight and insulating properties.

Q: When should one choose custom particle sizes for LECA applications?

A: Custom particle sizes are recommended when specific engineering needs demand precise aggregate gradation, such as in specialized gardening systems, narrow filtration layers, or in concrete with unconventional strength or insulation requirements.

Q: Is LECA safe and environmentally friendly for all applications?

A: Yes, LECA is classified as non-toxic, eco-friendly, and odorless with a neutral pH. It does not decompose, dissolve in water, or release harmful substances, making it safe for a variety of uses, including those involving food crops and potable water.
