A concrete mix was designed for thin core walls in a tall building. A 28-day strength of 32 MPa is required. The exposure classification for durability purposes is for B2 and C. One hundred laboratory test results on the controlling mix show a standard deviation of 5.3 MPa (k=1.65). The density of uncrushed coarse aggregate is 2850 kg/m3 and its dry rodded density is 1600 kg/m3 and the maximum size to be used is 10 mm. The density of fine...
