Chen et al. [29] have carried out a detailed study of the methods for the prediction of the long-term behavior of rods of glass fiber-reinforced vinyl ester resin nsed to reinforce concrete building structure. As a measure of durability, tensile strengths are reported for bars of this material before and after exposure to alkaline solutions. In a typical example, the tensile strength of the exposure of glass fiber-reinforced vinyl ester resin changes from 100% to 80% after 400 days exposure and from 100% to 60% after 800 days of exposure to concrete. 

When the coloring of latex-modified mortar and concrete is required, alkali-resistant, weatherproof pigments are used. Furthermore, it is important that the pigments do not obstruct the stability of polymer latexes and the hydration of cements. Alkali-resistant glass, steel, polyamide, polypropylene, polyvinyl alcohol (poval), aramid and carbon fibers are employed as mixable reinforcements. Reinforcing bars for ordinary cement concrete are also used for the reinforcement of the latex-modified concrete.
