Abstract

The carbon nanotubes were synthetized directly on the surface of Portland cement particles. Mixing this new carbon/cement material with ordinary cement creates a modified cementitious substance, where carbon is perfectly dispersed in the volume. In presented work, the fracture energy and compressive strength of cement paste/mortar created from this new material was measured. The composites with weight fractions of carbon nanotubes/paste in the ranges 0-0.038 were prepared and mechanically tested. Slight increase in fracture energy and compressive strength was observed even in the low carbon weigh fraction 0.019.
