Mechanical wear is the damage caused by repeated wear, submergence and impact of cement floors and industrial plant floors. However, the mechanical wear of concrete is when the concrete is subjected to repeated mechanical friction, the first wear is the hardened cement paste layer or cement mortar surface layer. Because the strength and hardness of concrete, especially the strength and hardness of its surface layer is the most important wear resistance of the top concrete, the mechanical wear of concrete will greatly reduce the wear resistance of its surface layer. 因为混凝土是同时具备泌水性和离析性的，水泥浆和细的颗粒容易浮在表面，形成一个比较薄弱的面层，然而，这就是混凝土耐磨损的最薄弱的环节。在混凝土施工之前，我们必须要等到泌水停止后再将浮浆清除，然后抹平表面，以有效减少浮浆层。养护，也是环氧地坪施工的一个重要事项，合理的养护地坪，可大大增加地坪的使用年限，我们也建议可以适当延长养护时间，保证表面层有足够的强度。
Because concrete is both bleeding and segregation, cement slurry and fine particles are easy to float on the surface, forming a relatively weak surface, however, this is the weakest link in the wear resistance of concrete. Before concrete construction, we must wait until the bleeding stops to remove the floating slurry, and then smooth the surface to effectively reduce the floating slurry layer. Maintenance is also an important issue in floor construction. Reasonable maintenance of the floor can greatly increase the service life of the floor. We also suggest that the maintenance time can be properly extended to ensure that the surface layer has sufficient strength.
Reducing water cement ratio, adding superplasticizer and silica fume are all good measures to improve the strength and density of concrete. In order to improve the mechanical strength and wear resistance of cement floors, some wear resistant materials such as diamond and metal aggregate can be added to the surface concrete of airport floors and industrial plant floors which require high wear resistance. The concrete seal curing agent belongs to this type of product.
