Design of a concrete mix showed that 1 m3 of the mix contains 320 kg cement, 540 kg sand. A trial mix having the same proportions as the designed mix, enough for 6 standard cubes, containing 3.5 liters water was made. It is required to calculate the quantities by weight and volume for the construction of a concrete road having 25 m width, 1000 m long, and 0.25 m thick, given that the trial mix gave slump and compressive strength as designed.Specific density of cement = 3.15Specific density of aggregate (coarse or fine) = 2.7Unit weight of cement = 1440 kg/m3Unit weight of sand = 1600 kg/m3Unit weight of gravel = 1760 kg/m3 Using BSI Method Only

Note: Read the question carefully and give me right solution according to the question. I want clear solution with clear steps. A water contains 38.50 mg/L as CaCO3 of carbon dioxide, 288.00 mg/L as CaCO3 of Ca2+ and 53.00 mg/L as CaCO3 of Mg2+. All of the hardness is carbonate hardness. Using the stoichiometry of the lime soda ash softening equations, what is the daily sludge production (in dry weight, kg/day) if the plant treats water at a rate of 56.00 MGD? Assume that the effluent water contains no carbon dioxide, 30.0 mg/L as CaCO3 of Ca2+ and 10.0 mg/L as CaCO3 of Mg2+. Be sure to calculate the mass of CaCO3 and Mg(OH)2 sludge produced each day.
I) Two aggregates (Al and A2) were obtained from the field. A sieve analysis was performed on each sample, and the samples (originally 500g in mass) were brought to the oven dry condition (OD) and weighed.
