MAKING AND CURING OF CONCRETE TEST SPECIMENS what is the volume of concrete?
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
