The following requirements are specified for the mix design as follows; Make a trial mix of 0.25 m' conerete for a mass concrete conditions. Show your results in a table. Minimum specified compressive strength = 35 MPa at 28 days; Standard Deviation=5 MPa (risk probability is 1 in 4 and the number of tests is 25 tests); Cement type I; Max. Aggregate size = 50 mm; Maximum allowable free - water/cement ratio = 0.6; Minimum allowable cement content = 500 kg/m'. * use volume method in your calculations. * No plasticizer, air-entrainment, or additives are used. * make the required assumptions if needed.
