thanks, i need this for my oral defense, but i cant find what particular property
It wouldn't be bulk (solid) plastics that would used in cement modification, it is more likely to be polymer latex dispersions - colloidal dispersions of small spheres of polymer, the material resembling a white milky liquid. The dispersion is water based, as is cement mix, so the two can easily be combined, and then when the cement dries and sets off, the interior of the porous structure of the cement block will contain a monolayer of the polymer. They are often used for imparting moisture resistance to the concrete, and also a degree of flexibility which reduces environmental degredation.
