1 part cement for M20 Concrete Ratio: This is typically measured in weight or volume. Cement acts as the binding agent in the concrete mix, providing strength and cohesion. 1.5 parts fine aggregate for M20 Concrete Ratio: Fine aggregate, usually sand, is responsible for filling the voids between the coarse aggregates. It contributes to the ...

Types of Grading of Aggregates. Dense- or well-graded aggregate – Has gradation close to the FWHA maximum density grading curve. Gap-graded aggregate – Has only a small percentage of particles in the mid-size range. Uniformly graded aggregate – Composed mostly of particles of the same size. Open-graded aggregate – Contains …
