The following requirements are specified for designing a concrete mix as per the British Bullding Research Establishment method. Calculate the unit contents (kg/m 3) of cement, water, fine aggregate, and coarse aggregate to make 1 m^3 of concrete. Target mean compressive strength is 30 MPa at 7 days Portland cement class is 42.5 Slump required is 30-60 mm Maximum aggregate size is 20 mm Maximum cement content is 350 kg/m^3 Additional Information: The aggregates to be used are crushed; the bulk density is 2.7 The fine aggregate has 50% passing a 600 um sieve The coarse aggregate is to be a blend of 10 mm and 20 mm stones The following requirements are specified for designing a concrete mix as per the British Bullding Research Establishment method.
