Dear Mr Sahu

I am just starting. But I have done testings to examine the influence of some minor and surface-active substances ?n cement and concrete properties. Simultaniously I'm trying to generate nanoparticles with attrition&milling in liquid phase and after that stabilization of the colloid solution, using  very fine natural minerals of different types. I'm also studying all of the processes for generating nanoparticles and also all informations regarding nano science.

With best regards
