Abstract
The present invention relates to a quantitative evaluation method for concrete workability based on bottom resistance, including the following steps: step 1, carrying out a test for bottom resistance of fresh concrete; step 2, drawing a curve of inserting velocity of steel sheet over time; and step 3, quantitatively evaluating a concrete workability based on conditions of the bottom resistance. This method can quantitatively characterize the sinking condition of aggregate of the fresh concrete by effectively carrying out the test for bottom resistance of fresh concrete, calculating the inserting velocity of concrete and drawing the curves of displacement and velocity over time, so as to achieve the quantitative evaluation for concrete workability and overcome the defects of conventional methods that it is difficult to quantitatively characterize the segregation degree of concrete.
