Rheological Property and Durability of High Strength Concrete Using Zeolite Powder and Microsphere

Abstract:

The rheological property of fresh high-strength concrete (HSC) and mechanical properties, self-shrinkage and resistance to chloride ion permeability of hydrated HSC were studied on the basis of the closest packing theory. Results showed that the packing density of composite powder was the highest when the content of microsphere was 30.0%; when the content of zeolite powder added to concrete varied from 0.0% to 4.0%, the rheological and discontinuous property of concrete would be improved and its viscosity would be increased; meanwhile, compared to the standard concrete, the self-shrinkage of concrete with 2.0% zeolite powder at 1d, 3d, 7d and 28d was decreased by 77.1%, 49.6%, 44.0% and 38.1% respectively; finally, the resistance to chloride ion permeability of hydrated HSC with zeolite powder was improved with a result of 18.5% reduction of electric flux at 28d.
