Abstract: Cement-based materials are known as having high compressive strength and low tensile strength. Therefore, the use of these materials in practice involves their combination with reinforcements. Next to conventional steel reinforcements, especially types of fibers can be used for cement reinforcements.It was found that fabrics of adequate fibers and geometry could improve the mechanical performance of cement composites to a greater extent than that obtained with straight yarns not in a fabric form, due to increased fabric-cement bond by mechanical anchoring. Three dimensional fabrics allow the increased production and also provide reinforcement in the plane normal to the panel of the cement composite. The object of this paper is to present a new development of warp knitted fabric structures for reinforcing cement products. Two dimensional knitted fabrics as well as three dimensional fabrics will be discussed and evaluated from a production point of view as well as from the focus of concrete strengthening.
