The basic principle which is generally used for mix design for proportioning mixes is Abram's law for strength development. According to this law, for any given conditions of test the strength of workable concrete mix is dependant only on the water-cement ratio. Lesser the water-cement ratio in a workable mix greater will be its strength.
OR. F'ck = fck + factor based on grade of concrete, whichever is higher For Mix design of M20 grade concrete Factor based on grade of concrete = 5.50. Standard Deviation = 4.00 F'ck= 20 + 1.65 X 4 = 26.60 N/mm2. F'ck = 20 + 5.5 = 25.50 N/mm2. Hence higher value of F'ck = 26.60 N/mm2 is to be used for design calculations. approximate ...
