Mobile Concrete Batching Plant

A In general batching is the process of measuring and combining the ingredients of concrete (cement, water, sand, aggregates) as per the mix design.Traditionally batching is done by volume. Batching accuracy is important. It is however recommended to do weigh batching rather than volume batching.

How to Calculate Lightweight Concrete Mixes

Standard concrete mixtures consist of four elements: Portland cement, sand, gravel aggregate and water. In many instances, a lightweight concrete is used to achieve a specific weight-per-square-foot. Lightweight concrete is achieved by substituting a lighter weight material for the gravel aggregate.

Ready mixed concrete is batched by weight and sold on a volumetric basis, either as a cubic yard or a cubic meter. If the mixture proportions for concrete mixtures are not

Classification of Aggregates

The most important aspect of lightweight aggregate is the porosity. They have high absorption values, which requires a modified approach to concrete proportioning. For instance, slump loss in lightweight concrete due to absorption can be an acute problem, which can be alleviated by prewetting (but not saturating) the aggregate before batching.

Batching Dry Aggregates in Concrete

For normal-weight concrete, batching dry aggregates shouldn't cause any problems. Most air-dry aggregates don't absorb more water than a percent or so by weight of the aggregate. The batch plant operator can correct for the amount of water absorbed by adding more water at the plant.
