Effects of natural zeolite and sulfate ions on the mechanical properties and microstructure of plastic concrete
文献摘要：
One of the strategic materials used in earth-fill embankment dams and in modifying and preventing groundwater flow is plastic concrete (PlC).P1C is comprised of aggregates,water,cement,and bentonite.Natural zeolite(NZ) is a relatively abundant mineral resource and in this research,the microstructure,unconfined strength,triaxial behavior,and permeability of P1C made with 0％,10％,15％,20％,and 25％ replacement of cement by NZ were studied.Specimens of PIC-NZ were subjected to confined conditions and three different confining pressures of 200,350,and 500 kPa were used to investigate their mechanical behavior and permeability.To study the effect of sulfate ions on the properties of PlC-NZ specimens,the specimens were cured in one of two different environments:normal condition and in the presence of sulfate ions.Results showed that increasing the zeolite content decreases the unconfined strength,elastic modulus,and peak strength of PlC-NZ specimens at the early ages of curing.However,at the later ages,increasing the zeolite content increases unconfined strength as well as the peak strength and elastic modulus.Specimens cured in the presence of sulfate ions indicated lower permeability,higher unconfined strength,elastic modulus,and peak strength due to having lower porosity.
