Polymer concretes click here are mixtures of aggregate and any of assorted polymers and should be reinforced. The cement is costlier than lime-based mostly cements, but polymer concretes Nonetheless have benefits; they have sizeable tensile energy even without reinforcement, and they are mainly impervious to h2o.
