Research on the Technology of Adding Fly Ash to Expressway Concrete
Concrete is the main engineering material in engineering construction and plays an indispensable role in engineering construction.Moreover,the concrete mix ratio directly affects the construction quality and cost of concrete engineering.After replacing cement with fly ash in the same proportion,the water consumption can be reduced while achieving the same workability(slump or flowability),which is commonly referred to as the"water reducing effect".It can accelerate the release rate of water in the cement flocculation structure,optimize the rheological properties of the mixture,and thus improve the lubrication effect of the slurry.Based on the actual situation of the project,a large number of experimental studies have been carried out.Through experimental research,it has been found that adding an appropriate amount of fly ash will not significantly reduce the strength of concrete,and the various performance indicators of concrete can still meet the requirements of relevant specifications.
