2020-7-1 From table 1 of IS 10262 assumed Standard Deviation, s = 4 N/N/mm². Therefore, target strength of concrete = 25 + 1.65 x 4 = 31.6 N/mm². But as per MORTH 5th revision Table 1700.5 required target mean compressive strength = 25 + 11 = 36.00 N/mm² where 11 is the current margin. 4 SELECTION OF WATER•CEMENT RATIO

190 L. To find the design mix ratio, divide the calculated value of all materials by the weight of cement. Therefore Mix Design Ratio of M25 Grade concrete by weight is Cement: F.A: C.A: Water = 1: 1.9 :3.1 : 0.50. Note: This is a Design mix ratio by weight which is different from the Nominal volumetric mix ratio.

From Table 4 of IS 10262:2019, maximum water content for 20 mm aggregate = 186 liter (for 25 to 50 mm slump range) but for an increase by about 3 percent for every additional 25 mm slump so here estimated water content for 125 mm slump = 186+ (9/100) x 186 = 202 liter.
