ZrO2 nanoparticles' effects on split tensile strength of self compacting concrete

Materials Research, 2010
In the present study, split tensile strength of self compacting concrete with different amount of ZrO2 nanoparticles has been investigated. ZrO2 nanoparticles with the average particle size of 15 nm were added partially to cement paste (Portland cement ...
