Fiber-reinforced cementitious composites
TL;DR: In this paper, the use of light, high tensile strength fibers as reinforcing agents was proposed to improve the bonding of a composite reinforcement agent to the cement portion of the composite.

Modelling of fibre pull-out from a cement matrix
TL;DR: In this article, a theoretical model motivated by observations of fiber surface abrasion is developed to predict the pull-out force versus displacement relationship, taking into consideration the variation of the frictional fibre-matrix bond strength with fibre slippage distance.
