i need the answer quickly Q: Using the American Method, design a concrete mix for a continuous foundation with a crosssection of 1500 mm x 400 mm. The smallest spacing between reinforeing steel is 150 mm. Theaverage compressive strength required for the concrete at 28 days is 30 MPa and slump to be in therange of 30-50 mm. The foundation is moderately exposed to brackish water in a cold climate and isintended to be watertight. The raw materials used for this concrete have the following properties:• Cement used is Sulphate resistant Portland cement with a specific gravity of 3.15.The available coarse aggregate has a maximum size of 20 mm, a dry-rodded unit weight of1760 kg/m3, a bulk specific gravity (SSĐ) of 2.7, absorption capacity of 0.5%.The fine aggregate has a bulk specific gravity (sSD) of 2.6 and a fineness modulus of 2.6. Theaggregates conform to the ASTM C33-84 requirements for grading.Combined specific gravity of both fine and coarse aggregate = 2.65• NB: Do not Adjust the amount of water in the mix designNote: for calculating the sand:• Use the weight method. Use the concrete density formula to obtain the precise density ofconcrete. Do not use the approximate density obtained from table 3-12.

Compressive stress is the force that deforms the material in a way that reduces the volume of the…
