Smart concrete using nano particles

Nano concrete Addition of nano particles gives significant improvement to concrete than conventional concrete. Addition of nano particles improves the bulk properties of materials by controlling or manipulating at the atomic scale due to nanoscale attack by alkali silicate reaction. It is possible to obtain thinner final products and faster setting time besides lower levels of environmental contamination. Nano concrete is a concrete made with Portland cement particles that are less than 500nm as a cementing agent as against normally used cement particle which range in size from a few nano-meters to a maximum of about100 micro meters. The benefits are cessation of contamination caused by micro silica solid particles, lower cost per building site, high initial and final compressive and tensile strengths, good workability, cessation of super plasticizing utilization and cessation of silicosis risk of concrete. Nanomaterials used are nano-silica (nano-SiO2), nano-titanium oxide (nano-TiO2)
