Any mixture of these things and Some others may possibly lead to a mixture that's way too harsh, i.e., which isn't going to move or spread out easily, is challenging to get into your formwork, and that is tricky to area end.[75]

Polymer concretes are mixtures of combination and any of various polymers and may be reinforced. The cement is costlier than lime-centered cements, but polymer concretes Even so have strengths; they may have considerable tensile energy even without reinforcement, and they are mostly impervious to drinking water.
