Standared deviation for Cube Strength
Standard deviation for every grade of concrete shall be calculate separately. Because the value of standard deviation various based on the material used and batch mix. Based on the number of trials and based on the Indian standards. Calculation sheet some fillup data as Grade of mix design, no. of Cube strength sat, Indiviusal cube strength, Find out standared deviation & Coefficient of variation etc
