Eden Innovations(ASX:EDE) said trial results with its EdenCrete products in multiple Indian concrete applications for the Delhi area have been encouraging, with recent trials comparing its carbon nanotube-enriched EdenCrete concrete to standard concrete mixes showing encouraging results for concrete performance and cost reduction, according to a Monday Australian bourse filing.

The company said special focus has been on flexural strength and abrasion resistance for road application at low-cost dosages, and the addition of strength buffer in high-strength mixes from 50 megapascals and above for high-rise applications, allowing cost reduction from reduced ordinary Portland cement and expensive micro silica additions.

Eden intends to expand trials in the Delhi area and other Indian areas with significant high-rise activity, and to increase staff count to accommodate the increased interest, it added.

The company's shares fell past 10% in recent Monday trade.
