We are the leading manufactures, technical suppliers of Nano Silica in Chennai, Tamil Nadu,
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.
