The question is as follows:-
Q) Design the concrete mixture for the slab
2. A reinforced slab concrete foundation is to be poured for a building. The building is to be constructed near Edmonton. The slab will be in direct contact with the soil, and the soil typically has a sulphate content of 0.3 percent by mass. The minimum rebar spacing in the slab is 100 mm. The contractor is certain that his workers can place a concrete with a...

Q1// Use the ACI method to design a concrete mix which is required to obtain f'c28= 34.5MPa and a slump of 75mm. the fineness modulus of the aggregate is 3.0, the bulk density of coarse aggregate is 1600 kg/m' and the maximum size is 25. Both the specific gravity of fine and coarse aggregate are 2.68. neglect the absorption and total moisture content.
