Abstract

Traditionally, the first cracking strain of plain matrix is used as the material property in the fiber reinforced cement based composites. It is used to indicate the tensile strength, and thus termination of the contribution of the matrix phase. In the presence of high volume fraction of fibers, formation of the first crack does not necessarily lead to the fracture instability, thus matrix is able to carry increasing loads. The strength of the matrix is thus dependant on the type, volume fraction, bond, and strength of the fibers. This paper investigates the tensile stress strain response of cement paste in the presence glass fibers. A test procedure is described which can characterize the toughening effect of various fiber types on the matrix properties.
