  3. You should actually learn what RACC is made from before flapping your gums and plasterboard is not load bearing. RACC contains cement, sand, lime power, and aluminium powder and no aggregate which is why it's so weak. Aggregate is crucial to concretes strength because aggregates work to arrest cracks when concrete is subjected to flexural loads..

  4. Breeze blocks contain cement sand and gravel (aggregate). The aggregate gives it extra strength. RACC contains cement, sand, lime power, and aluminium powder and no aggregate which is why it's so weak.
