IS:383-2016 IS:2386 IS:4031 IS:269-2015 IS:456-2000 IS:9103 IS:1199 IS:516 Some Important Points during Trial Combined grading and other property of CA & FA must be within limit as per IS 383 Cement not more then 2 month old for batter results. Concrete Temp. within  (-5) °C to 40 °C **** Note: In this trial I used OPC 43 CEMENT and achieved the target strength for M45 and almost near to M50 target strength. If we replace the OPC 43 cement with OPC 53 cement then the target strength of M50 can be achieved.
