Standard Deviation for Concrete Cube Test .
In the design mix of concrete, the target strength should be equal to the characteristic strength plus 1.65 times the standard deviation.. Why is it required for a concrete design mix? The concrete was produced from a certain mixture of different material and those all are having different properties.. In the design mix, the concrete was calculated by weight method so mistakes may happen.
