Concrete Strength Vs Time Graph
Compressive Strength The main measure of the structural quality of concrete is its compressive strength This property of concrete is commonly considered in structural design Depending on the mix (especially the watercement ratio) and time and quality of the curing compressive strength of concrete can be obtained up to 14 000 psi or more

Non destructive testing for determining the strength of
Similarly to obtain a relation for determining the compressive strength of concrete through UPV a graph shown in fig 6 has been plotted between the Velocity (V) from UPV (m/s) and the Actual Compressive Strength (f) – Relation obtained between the UPV (V) and the actual Crushing strength (f) of concrete is shown in eqn 2

How to Calculate Water
To calculate watercement ratio for mix design we need to collect some data like Target mean strength of concrete We can calculate it from ft = fck + 1 65 S where fck – The characteristic compressive strength of concrete (Grade of concrete which you want to design) S – The standard deviation obtained from the below table
