- Abstract
- An experimental study is carried out on the utilization of epoxy glass powder (EGP) as a percentage replacement of fine aggregate in concrete, which is a by-product of E-waste obtained after removal of metals from it. The specimens of concrete with and without EGP as fine aggregate are cured in a standard condition using the membrane to obtain mechanical properties and to exhibit a good strength. Results show that the weight of concrete is reduced in the range of 3% to 9% when it is replaced by EGP from 10% to 50%, respectively. For the constant water-cement ratio of 0.4, the workability of concrete is increased as the EGP increases. But the compressive strength of concrete is decreased as the EGP increases. The compressive strength of concrete identified with EGP squander more by 10% strength with 10% EGP, and the remaining mix is lesser in examination with control blend solid specimen, but it is in the required range of M20 grade. The Support Vector Machine (SVM) method, which is a unique specific loss function and kernel type, is applied to experimental data. SVM with different kernel functions is performed, among them, erbf kernel function gives higher CC 0.9623 and lower RMSE 1.0939 for test data, respectively, as compared to other functions. The predicted test compressive strengths are closed to observed values.
