Abstract:
This article provides a description of the fracture energy characteristics analysis of Portland pozzolanic cement concrete containing cassava flour with different percentages (1, 2, 3, 4, and 5%) at 90 days of curing. For notch-beamed structures, three-point bending examinations are conducted of Portland pozzolanic concrete blended cassava flour to get the force-crack mouth open movement (CMOM) graphs. Additionally, the behaviour of the slope of force movement, elements influencing the fracture energy, and the specimen breaking way are described. Finite numerical simulation analysis is the approach used to execute an inverse analysis process to determine the fracture energy evolution's trend. A nonlinear inverse analysis algorithm is implemented, and a model for minimizing damages is used to characterize the softening behaviour. Because the softened deformation mode that was used didn't take bounding impacts into account, most of the force-CMOM charts had to be changed. As a result, a reliable estimate of size-independent fracture energy of the Portland pozzolanic cement concrete containing cassava flour is achieved. The empirical observations test and the inverse analysis show that he fracture energy and further attributes of the Portland pozzolanic cement concrete incorporating cassava flour for cracking have been going up.
