Volvanic ash benefits discovered

Iceland-based engineering company 1849 Mannvit has revealed that ash from the eruption of the Eyjafjallajökull volcano could be used to improve concrete design. According to the company, the ash contains silicates and glass similar to ash from coal sources that is frequently used as reinforcement in concrete mixes.

Mannvit has said that addition of 5% volcanic ash improves the quality of the concrete but only 60% of the ash from the eruption is of sufficient quality for the application.
