Jeknavorian Consulting Services - Chemical Admixtures for Concrete 
Hello Sir,
I have a construction chemical company in india based out of mumbai and am interested in manufacturing of pc based admixture for m60 concrete i tried a lot of permutation and combinations but somehow not being able to get the desired results if you could help me out it would be great
Awaiting your positive response
Marmik,
I will be glad to assist you for the manufacture of PC based admixture to achieve 60 mPA concrete. The admixture product that is desired will likely be comprised of a combination of the PCE having the appropriate polymer architecture and formulated with various other additives. I can give direction on the desired polymer architecture with limited advice on synthetic procedures. I have significant experience with formulation for high strength concrete admixtures. When working with companies, I normally proceed under a consulting contract which assures confidential exchange of information as well as my consulting fee. Please advise if you wish to proceed, and I will be glad to send my consulting contract.
