TENSILE STRENGTH OF NANOFIBROUS CONCRETE

Results of testing nanofi brous-concrete test beams for axial tensile strength, for cleavage tensile strength, and for compressive strength have been given. Concrete matrices covering a broad spectrum of compressive-strength classes of concretes of construction grade were used as a basis. A macrolevel fi ber (steel or polymeric) or a nanolevel fi ber (carbon nanotubes) was made part of a concrete matrix. An increase of 80% in the axial tensile strength and of 145% in the cleavage tensile strength was recorded in the nanofi brous-concrete test pieces. Diagrams of axial tensile straining of the test pieces have been obtained.
