The increasing demand for lightweight concrete in the construction industry is anticipated to propel the use of the product. Lightweight concrete is preferred over ordinary concrete owing to many reasons such as improved fire resistance, less thermal expansion, and better sound absorption. Other than concrete, the use of natural zeolites is prevalent in dimension stones, lightweight aggregates, and soil stabilizers under construction materials.
Soil amendment and water treatment applications are gaining importance across the globe on account of increasing environmental concerns. The groundwater contamination caused by soluble nitrogen-based fertilizers is a major environmental concern. Natural zeolites restrict the nitrification of ammonium to nitrate, which results in reduced nitrate leaching. Also, natural zeolites enrich the soil and contribute to the development of a healthy plant.
