Not just compressive strength it also enhance durability in design period rather than just OPC. India has an advantage of having 100 Million Tonne of fly ash but should use wisely. QC at source is very important. it is much greener concrete with FA. it is not just using 30% of industrial waste ...it is about saving 30% of precious portland cement that too with a quality advantage.
