Advanced Coatings to Improve the Durability in Continuous Glass-Fibre Reinforced Concrete

“…This leads to the filaments inside the roving being only partially surrounded by crystallised material, while the filaments on the outside of the roving are in contact with the undisturbed matrix. Thus, the inner filaments contribute less to the load bearing capacity than the outer ones, and macroscopically the roving fails at loads far below its nominal tensile strength [2][3]. To circumvent this situation, we have recently developed reactive cement-in-polymer dispersions, which have the ability to dissolve in neutral or alkaline aqueous media, leading to the formation of a cementitious matrix [4][5].…”
