Ready Mixed Concrete, or RMC as it is popularly called, refers to concrete that is specifically manufactured for delivery to the customer’s construction site in a freshly mixed and plastic or unhardened state. Ready Mixed Concrete is bought and sold by volume – usually expressed in cubic meters. RMC can be custom-made to suit different applications. We produce concrete of grade of M7.5, M10, M15, M20, M25, M30 & above.
- Concrete available in large volumes at short notice, factory made with supervised mixing of concrete. Better quality.
- Storage of aggregates, sand and cement in large quantities at construction site is not required. Less wastage.
- Noise and dust pollution at site is reduced.
Mix design is largely different from conventional systems. More or less it is based on the experience of the engineer who is designing. General Considerations are written below
- Fluidity and viscosity have to be controlled. Fluidity is required, but there should be limits as it will start affecting viscosity. Limitation of water/powder ratio and the addition of viscosity enhancing modifiers give optimal performance
- Paste act as a vehicle for aggregate grains so paste volume has to be greater than the volume of voids in aggregates. Aggregates should be covered with paste so that lubrication is there and fluidity is enhanced.
- In order to control shrinkage, a significant amount of mineral additions is made which not only control shrinkage but enhance final strength.
- Lower coarse aggregate with the size of about half an inch is used to enhance flowability and passing ability.
- Increased quantity of superplasticizers is used.
- Increased quantity of Viscosity Enhancing Agents is used.
