Batching, Mixing, Placing and Compaction of Concrete

Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.When the quantity of cement to be batched exceeds 30% of scale capacity, the measuring accuracy should be within 1% of required mass. If measuring quantity is less than 30%...

Concrete Mix Ratio | What Is Concrete Mix Ratio | Types of ...

This concrete mixture ratio of 1 part cement, 1 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 2500 to 3000 psi.. Mixing water with this cement, sand, and aggregate will form a paste that will bind the materials together until the mix hardens. This strength properties of the concrete are inversely proportional to the water-cement ratio.
