| Abstract: | Large error exists when using Bowromi formula to speculate 28 d compressive strength of lightweight aggregate concrete.By measuring 28 d compressive strength of lightweight aggregate concrete with various mixing ratios and the corresponding compressive strength of cement block,the Bowromi formula was perfected using multiple linear regression method.The amended formula can forecast 28 d compressive strength of lightweight aggregate concrete more accurately to provide meaningful guidance for practice. |
