A project specifies a concrete strength of 24.1 MPa. Materials engineers will design the mix for a strength higher than that to account for variables.
A. Calculate the required average compressive strength of the mix design if the mixing plant has a standard deviation of s = 3.8 MPa.
B. Using the ACI code equation, estimate what would be the modulus of elasticity of this concrete at the required compressive strength.
