Test MethodsPoint Load Test W(width) = (W1 + W2)/2

Diametral core test - Length / Diameter ratio >1

Axial core test - Length / Diameter ratio = 0.3 - 1.0 (Length = D(depth)and Diameter = W(width))

Block test D(depth)/W(width) ratio = 0.3 - 1.0 and L . 0.5W

P = load at failure in MNIs = uncorrected point load strength index in MPa

F = size correction factor

Is(50) = corrected point load strength index in MPa
