“…Hence, an appropriate hybridization design of the used steel fibres in the production of UHPFRC can be treated as a potential method to enhance the fibre efficiency. In recent years, the research focusing on the application of hybrid fibres in UHPFRC or influence of hybrid fibres on the UHPFRC properties can also be found in the literature [29,44,46]. However, the research focusing on the application of three different types of steel fibres simultaneously (e.g.…”

“…The relationship between experimental factors (deposition temperature and hydrogen flow) and responses (wear rate and friction coefficient) was analyzed by Design Expert software. Fitting an appropriate model and verifying the efficiency of the selected model are two main steps in the process of modeling [22].…”

Box-Wilson experimental design method, known as central composite design, is the design of any information-gathering exercises where variation is present. This method was devised to gather as much data as possible in spite of the low design cost. This method was employed to model the effect of mixing factors on several performances of 60 MPa high strength self compacting concrete and to numerically calculate the optimal mix proportion. The nonlinear relations between factors and responses of HSSCC were approximated in the form of second order polynomial equation. In order to characterize five performances like compressive strength, passing ability, segregation resistance, manufacturing cost and density depending on five factors like water-binder ratio, cement content, fine aggregate percentage, fly ash content and superplasticizer content, the experiments were made at the total 52 experimental points composed of 32 factorial points, 10 axial points and 10 center points. The study results showed that Box-Wilson experimental design was really effective in designing the experiments and analyzing the relation between factor and response.
