A trial mix is required for a pavement slab being constructed exposed to freezing and thawing as well as deicing agents . The trial mix design strength is 32 MPa (including overdesign) with a 75 mm slump. For the sand; FM = 2.80 and its absorption is 1.5%. The coarse aggregate has a nominal maximum size of 25 mm with an absorption of 1.6% and a dry rodded density of 1460 kg/m3. Determine the mix design amounts for the concrete if the coarse aggregate contains 6% water. (keep all calculations and answers to one decimal place except where indicated. That is, round to one decimal place) Design Water = kg/m3 Water to Cement (W/CM) ratio = (two decimal places) Cement Content = kg/m3 Volume of coarse aggregate per unit volume of concrete = (two decimal places) Estimated total mass of concrete = kg/m3 Design mass of coarse aggregate = kg/m3 Actual mass of coarse aggregate = kg/m3 Actual mass of fine aggregate = kg/m3 Actual mass of water added = kg/m3
please quickly thanks !!

You are working on a concrete mix design that requires each cubic yard ofconcrete to have 0.45 water–cement ratio, 1165 kg/m3 of dry gravel, 4% air content, and 335 kg/m3 of cement. The available gravel has a specific grav-ity of Ggravel = 2.7, a moisture content of 1.6%, and absorption of 2.4%. The available sand has a specific gravity of Gsand = 2.5, a moisture content of4.8%, and absorption of 1.5%. For each cubic meter of concrete needed onthe job, calculate the mass of cement, moist gravel, moist sand, and waterthat should be added to the batch. Summarize and total the mix design whenfinished (don’t include air entrainer in summary).
Q3/: TILM We require a mix with a mean 28-day compressive strength of 26.5 MPa the size of the member and the spacing of the reinforcement require a slump of 50 mm and a Q maximum size of aggregate of 20 mm. Portland cement type I is used with specific gravity of 3.15, dry-rodded unit weight of coarse aggregate 1700 kg/m³ and bulk specific gravity (SSD) of 2.55. The fineness modulus of fine aggregate is 2.8 and bulk specific gravity (SSD) of 2.5. No air entrainment is required. Neglect water absorption and moisture content of both aggregates. The aggregates conform to the ASTM C33-84 requirements for grading. Estimate the quantity of (cement, fine aggregate, coarse aggregate and water) for 1m³ concrete.
