• Aggregates are divided into either ‘coarse’ or ‘fine’ categories Coarse aggregates are particulates that are greater than 475mm The usual range employed is between 95mm and 375mm in diameter Fine aggregates are usually sand or crushed stone that are less than 955mm in diameter • Typically the most common size ofFor concrete of 1:2:4 mix proportion, first four boxes of coarse aggregates, then two boxes of sand and one bag of cement is put into the machine mixer The mixer is then revolved to mix the materials in a dry state and then water is added gradually to the required quantity, ie 25 to 30 liters (5 to 6 gallons) per bag of cement to have the required watercement ratioWork Procedure for Cement Concrete Works For Mixes 1:2:4
