A concrete mix was designed for a concrete road pavement (i.e.heavy mass concrete). A 28-day strength of 26 MPa is required. Theexposure classification for durability purposes is C. One hundredlaboratory test results on the controlling mix show a standarddeviation of 5.3 MPa (k=1.65). The density of crushed coarseaggregate is 2850 kg/m3 and its dry rodded density is1600 kg/m3 and the maximum size to be used is 10 mm. Thespecific gravity of fine aggregate is 2750 kg/m3 and itsfineness modulus is 3.0. The high early strength cement used has adensity of 3150 kg/m3.
Find the weight (in kg) of cement, water, fine and coarseaggregate for this mix, required to make a 0.25 m high x 3.6 m widex 12 m long concrete pavement using the ACI Method.
