Activity Improvement of Sticky Portland Cements by Methods of Mechanical Activation

Abstract:

Article Preview

The article presents experimental data on the improvement of physical and mechanical properties and structure of fine-grained concrete by mechanical activation of sticky cement in various apparatuses. It is established that the use of mechanoactivation technologies allows controlling the surface characteristics of cement in a wide range, its granulometric composition, as well as the physical and mechanical characteristics of concrete products. It is revealed that the efficiency of grinding machines that realize various mechanisms of disperse action is not the same. The highest indexes belong to the concrete containing cement, which is mechanically activated on the planetary ball mill AGO-2.
