Advantages

Mortar with 74 μm rubber powder shows significantly increased pore solution resistance (Rs) and charge transfer resistance (Rct1)

74 μm rubber powder outperforms 180 μm rubber powder

After 30 days of exposure, rubber powder effectively improves mortar performance against stray current and sulfate deterioration
