What we have learnt
- Ready-Mix Concrete is manufactured at a central location and delivered to construction sites, enhancing quality control and reducing wastage.
- There are multiple types of RMC, each suited for different construction requirements and emphasizing the importance of quality control and efficient transportation.
- Modern RMC technology includes innovations like Self-Compacting Concrete and Green Concrete, aimed at improving performance and reducing environmental impact.
Key Concepts
- -- ReadyMix Concrete (RMC)
- A type of concrete produced in a batching plant and delivered in a fresh state, known for its uniform quality and efficiency.
- -- Quality Control
- Methods used to ensure the uniformity and desired performance of concrete, including various tests such as slump and cube compression tests.
- -- SelfCompacting Concrete (SCC)
- Concrete that can flow under its own weight without the need for vibration, ideal for complex formwork.
- -- Green Concrete
- Concrete that incorporates recycled materials, reducing its environmental impact.
