Concrete mix made by the batching process is very cohesive. Batching of concrete ingredients also rectify the bulkage correction because excessive water can cause loss of cohesiveness and can also lead to segregation or bleeding in concrete which results in poor quality of concrete. If any batching errors in cement and fine aggregates (sand
Oct 22, 2020 · A concrete batching plant (Бетонная установка) is a vital construction equipment that aids in producing concrete through the mixing of a variety of elements.Some of these include cement, sand, water, air, and aggregates. Concrete is a commonly used material due to its strength and durability, thus applicable in all types of projects.

Concrete: Manufacturing Process . A good quality concrete is essentially a homogeneous mixture of cement, coarse and fine aggregates and water which consolidates into a hard mass due to chemical action between the cement and water. Each of the four constituents has a specific function. The coarser aggregate acts as a filler.
Batching of Concrete. It 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 is as follows
