Effects of Cement–Polymer Interface Properties on ...
Polymer fibers are widely added to concrete to enhance tensile properties and ductility. Although there is a large body of data on this subject, the nanostructure and nanomechanical properties of the polymer fiber cement interface, which is pivotal in the design of robust polymer reinforced concrete, are still not completely known.

2018-2-7 The electric permittivity is a material property that relates to the dielectric and electromagnetic behaviors. This work reports the effect of polymer admixtures on the permittivity (2 kHz) of cement paste. The permittivity is increased significantly by the addition of either methylcellulose (dissolved) or latex (styrene–butadiene, not dissolved), due to the capacitance of the interface ...
