01-10-2019  Table 8 presents the nine optimized mix designs (3 different cements with 3 different additions). Firstly, we can see that the 28-day compressive strength of the concretes was above 38 MPa when silica fume was used (mix designs 7 to 9). Three mix designs gave compressive strengths between 38 and 40 MPa (mix designs 2, 4 and 5).
