## Calculate the amount sand-aggregate, Mechanical Engineering

Assignment Help:

Calculate the amount of cement, sand, aggregate, and water needed to create a concrete mix with a 28-day compressive strength of 34 MPa for a 10 m x 10 m x 0.25 m structure given the following conditions: allowed slump = 10 cm and only 3.8 cm (1.5 in) aggregate with 2% moisture and coarse sand with 4% moisture are available for this project. Assume no air entrainment in your calculations.
