Portland cement is used for making mortar and concrete which has been a popular construction material in the world for the past century or more. However, some trouble of cement mortar and concrete such as low tensile strength, low chemical resistance, large drying shrinkage, and delayed hardening. To minimize these troubles, many attempts to use polymers have been made. One such attempt is use of polymer as the binder in concrete, which is made by the innovating ordinary cement mortar or concrete with polymer additives such as water-soluble polymers, liquid resins, latexes, redispersible polymer powders and monomers.
