UHPRAC mix ratio optimization based on simplex-centroid design method

In the report， aimed at establishing the quantitative relationship between the compressive strength and splitting tensile strength of UHPRAC and the composition of each material with the least experimental amount， the simplex-centroid design method was used to optimize the composition of each material of UHPRAC. According to the requirements of the compressive strength and splitting tensile strength of the mechanical properties of UHPRAC， the optimal UHPRAC mix ratio was determined. At the same time， the method could also be used to predict the compressive strength and splitting tensile strength of UHPRAC prepared with different material composition ratios.
