Hydrophobic cement
In places of high rainfall and humidity normal cement tends to set when stored, due to mositure present in the atmosphere. By grinding the cement clinker with water repellent film forming substance like oleic acid, a water repellent film is formed around cement particle during manufacturing itself. This prevent setting of cement during storage.
During mixing with aggregates this film is broken and cement behave as ordinary cement.
