The Influences Of Cement Particle Shape On The Ability Of Superplasticizer

Studies have shown that when the cement particle shape is a crushed stone shape, the added superplasticizer has a significantly stronger effect than when the cement particle shape is a pebble shape. It can be understood that when the cement particles in the state are mixed, it is easier to form a flocculation structure, the formed flocculation structure is more stable and the structure is more continuous, which is conducive to the superplasticizer to exert its own effectiveness. The flocculation structure composed of pebble-shaped cement particles is prone to collapse. Even if the superplasticizer is not added, a part of the free water will radiate and join the mixing of cement slurry. In this way, the effect of the superplasticizer is reduced. Can't fully play out.
