Large-slump road pump concrete mix proportion design method based on cohesiveness
The invention discloses a cohesiveness-based large-slump road pump concrete mix proportion design method, and relates to the field of road construction. The invention discloses a cohesiveness-based large-slump road pump concrete mix proportion design method. The method comprises the following steps: determining a pressure bleeding rate allowable value of concrete; according to the design parameters of the concrete pavement, carrying out design and trial matching work of the concrete pavement mix proportion, and calculating to obtain a pressure bleeding rate standard value of concrete; calculating a temperature correction coefficient and a transportation time correction coefficient; adjusting a pressure bleeding rate standard value of the concrete based on the temperature correction coefficient and the transportation time correction coefficient to calculate a pressure bleeding rate design value of the concrete; and determining whether the design value of the pressure bleeding rate of the concrete meets the allowable value of the pressure bleeding rate of the concrete or not. The cohesiveness-based large-slump road pump concrete mix proportion design method can predict and ensure that the cohesiveness of the prepared concrete meets the construction requirement in the concrete mix proportion design stage, so that the concrete quality is ensured.
