Nano silica in the construction industry, extensive research is going on to improve the performance of various building materials and development of durable and sustainable concrete. Among all the nano-materials, nano-silica is the most widely used material in the cement and concrete to improve the performance because of its pozzolanic reactivity besides the pore-filling effect. concrete strength is influenced by lots of factors like concrete ingredients, age, ratio of water to cement materials, etc. Nano-silica incorporation into concrete resulted in higher compressive strength than that of normal concrete to a considerable level. for nano-silica blended concretes up to maximum limit of 2% with average particle size of 15 and 80 nm. Same results were obtained for split tensile and flexural strength.

The building materials industry is the biggest user of Iron Oxide Pigments. Uses include colouring concrete and mortar because of their good dispersability and good tinting strength. They are extensively used in the manufacture of Paving Blocks, Chequered Tiles, Designer Tiles, Stamped Concrete etc.
Paints industry is the second largest user of Iron Oxide Pigments. Most paint applications require use if micronized and dispersible grades of pigments to get optimum colouring effects and maintain paint film strength.
Pigments used in Plastics need high purity, tinting strength, high heat resistance and good dispersibility.
Special applications of Synthetic red Iron oxide include that in Ceramic Colours, Drugs, Cosmetics, Rubber, Brake Linings, Wood Polish, Cork Sheets, Fertilizers and Cattle Feed. New applications include catalysts in petroleum industry, in oil drilling rigs, in compound pigments, copy machine powder, and magnetic differentiate materials.
