Based on standard curing blocks' experimental results,regression compressive strength equation with nondestructive parameter-test block strength is established.According to blocks' test results under the same curing condition and adopted correction factor method,corrected regression compressive strength equation with nondestructive parameter-entity strength that is approximated to actual project is brought forward.Related to project of somewhere buildings,nondestructive check is done on the spot and structural entity compressive strength is concluded by corrected regression equation.Regression conclusion accords with project fact and it brings references to forecast compressive strengths of buildings of somewhere regions.
