Answer:
Yes, because both design compressive stress is greater than 4000 psi
Explanation:
To design a concrete that satisfy the requirements of ACI code for 4000 psi concrete
<u>Step 1: </u>design the compressive stress, using the two equations below
-------equation 1
where;
is the design compressive stress
is the critical stress = 4780 psi mean strength
s is the standard deviation = 525 psi
= 4076.5 psi
<u>Step 2:</u> design the compressive stress, using the second design equation
-------equation 2
= 4056.75 psi
Therefore, since both compressive stress is greater than 4000 psi, the concrete satisfies the requirements of ACI code for 4000 psi concrete
