how to do mix design of concrete as per is 10262 : 2019 : is 456 : indian code

High strength concrete mix design : M 70 grade concrete design as per 10262 : 2019 Indian code :    • High strength concrete mix design : M 70 g...   in this video we are going to see how to do mix design of concrete as per 10262 2019. we will learn the concept of concrete mix design. how to do the calculation of concrete mix design. steps for concrete mix design are 1. TARGET STRENGTH FOR MIX PROPORTIONING f ’ck = fck + 1.65 S or f ’ck = fck + X whichever is higher. where f ’ck = target average compressive strength at 28 days, fck = characteristic compressive strength at 28 days S = standard deviation, and X = factor based on grade of concrete. 2. APPROXIMATE AIR CONTENT 3. SELECTION OF WATER-CEMENT RATIO 4. SELECTION OF WATER CONTENT 5. CALCULATION OF CEMENT CONTENT 6.
