Estimating the Strength of Concrete Using Surface Rebound Value and Design Parameters of Concrete Material
並列摘要
This study estimates the strength of concrete, an attempt is also made to increase the accuracy of Calculating the strength, using the nondestructive test (NDT) surface hardness rebound value, material design parameters and regression analysis. The strength of the concrete specimens was 130-480 kgf/cm^2, and their ages were 7-38 days. In total, 166 standard specimens of concrete were grouped into 146 training examples and 20 test examples to estimate concrete compressive strength. Regression analysis was performed to establish a mathematical formula. Study results indicate that the correlation coefficient may reach 0.9622, indicating that the proposed method has referential value. Therefore, engineers may use this comprehensive approach to develop NDTs to determine concrete strength.
