What is not possible yesterday is possible today


What is not possible yesterday is possible today
By  Dr.V.V.Deshmukh 
We have laid concrete overlay 150mm thick on 150mm thick  GSB with the help of Thane unit of Prime Minister Gram Sadak Yogana at Murbad  The road is in good condition since two years
The road has been accepted widely across the PMGSY official but it could not progress further because of the high initial cost , though it has many advantages and life cycle study has proved it’s economical
It has made us work further on optimisation of mix design. we found that  if  we reduce the cost of admixture we will be able to reduce the concrete cost
We approach BASF  construction chemical company and they have promised us to give the admixture at half the rate.
The surprise:  ONE TIME IMPOSSIBLE IS POSSIBLE TODAY
