The influence of post-curing periods on polymer-mortar composites in corrosive media
Besma M. Fahad1, Mais A. Abdulkarem2.
Petroleum tanks and pipes made of steel or concrete suffer from the interaction between
the petroleum products and the materials of the tank or pipe. This work aims to overcome
this problem by adding polymer to the cement mortar and post cure it at the proper
period to modify its behavior when encountering petroleum products. Unsaturated
polyester was selected to prepare polymer cement composites. Four sets of polymer
cement composites were prepared. Two sets were cured at room temperature, but one was
kept without immersing in any solution. The other sets were post-cured at 50ºC for two
and four hours. Six groups of polymer cement composite specimens were immersed in a
solution. The solutions were water, 1N and 2N NaCl, kerosene, benzene, and oil engine. The
hardness and compressive strength were evaluated after 30 days. The hardness of the
specimens was altered according to the solution immersed. The best water absorption and
compressive strength results were obtained two hours post-curing specimens, whatever
the solution was immersed in. The corrosion rate for all specimens in every solution was
low. Again, the lowest corrosion rate was obtained after two hours of post-curing
specimens, which indicates that the addition of polymer and proper post curing will
improve the chemical resistance of the cement-sand mixture
