Concrete is made up of cement, sand, aggregates, and water. The right proportions of these components are key to a good mix.
The water-cement ratio determines the strength and workability of concrete. Too much water weakens the concrete, while too little makes it hard to work with.
- Nominal mixes, - Standard mixes, - Design mixes. Each serves a specific purpose based on the requirements of the structure.
The mix design process involves:
– Determining the workability. – Selecting the water-cement ratio. – Calculating the cement content. – Estimating the aggregate content. – Adjusting for specific conditions.
