“…The results of fresh concrete tests, including slump flow test, L-box test, and V-funnel test, indicate that the fresh concrete characteristics met the criteria of the European Federation for Specialist Construction Chemicals and Concrete Systems (EFNARC) for self-compacting concrete. Detailed results of the fresh concrete tests can be found in the previous study [14,15]. Table 2 presents the mechanical properties of concrete tested in the laboratory, including compressive strength, split tensile strength, modulus of rupture, and modulus of elasticity.…”

“…This research was conducted to numerically assess the shear performance of reinforced HSSCC beams containing 12.5% metakaolin and different proportions of silica fume. The numerical modeling was accomplished with the RESPONSE 2000 software, which relied on the mechanical parameters of concrete derived from prior investigations undertaken by the author [14,15].…”

High-Strength Self-Consolidating Concrete (HSSCC) is a type of concrete that possesses superior mechanical properties and can self-settle without the need for vibration assistance. Numerous advancements have been implemented to enhance the properties of HSSCC. In prior experimental work, the authors investigated the mechanical characteristics of HSCC with 12.5% metakaolin and 0-15% silica fume as a partial cement substitute. Since metakaolin and silica fume have smaller particle sizes than cement, they can fill voids between aggregate and enhance the concrete’s compactness. Further structural study is necessary to provide a more complete knowledge of the impact of partially substituting cement with metakaolin and silica fume. Using the Response 2000 program, this investigation analyzes the shear behavior of reinforced HSSCC beams. Laboratory-determined material mechanical properties were utilized as simulation input data. In this investigation, the maximum strength, deflection, and crack development of five beam models produced with varying material mechanical properties were investigated and compared.
