Concrete should not be deposited more rapidly than it can be spread, struck off, consolidated, and bullfloated and deposited continuously as near as possible to its final position. In slab construction, placing should be started along the perimeter at one end of the work with each batch placed against previously dispatched concrete.
The Fusion™ concrete batch plant is the next step in the evolution of concrete plant technology. By weighing each aggregate and adjusting moisture content in real time, it allows for precisely blended aggregates and optimized mix performance while minimizing material, operational and life cycle costs.

Batch Plant Control Office Concrete Batch Plant Control Office Concrete batch plant offices are a necessity for any portable concrete batch plant. Every concrete batch plant, central mix or transit mix, should come with a climate-controlled office to ensure computer automation controls longevity.
A: Curing is a very delicate part of producing precast concrete. However, the ability to cure properly and consistently at the plant offers a distinct advantage over cast-in-place concrete products, which must be cured at whatever ambient conditions exist on the day of pour. Proper curing ensures that water is not allowed to escape the product.
Mix Designs and Air Quality Emissions Tests of Crumb Rubber Modified Asphalt Concrete ROBE.RT F.

Cementitious Waterproofing products from W. R. Meadows are designed to protect reinforced concrete structures in two ways: against chemical attack and as a structural waterproofing.
This is because a volumetric mixer is a concrete plant, producing a stream of concrete rather than a batch. The modern volumetric mixer was developed in the early 1960’s. Harold Zimmerman took the concept of proportioning by volume, and designed a machine that could carry the ingredients needed to make concrete and produce it on site, rather than delivering concrete …

The minimum overlay thickness was 1-1/2 in. Superplasticizer was added to the mix. The concrete was mixed in a conventional batch plant, with the technical representative from the microsilica supplier providing assistance. The microsilica modified concrete overlay was finished and cured as prescribed by WSDOT's specification for LMC overlays.
To maintain or increase the efficiency of a precast concrete production, the production can be improved, the plant can be modified or the existing machines can be upgraded. Quite often it is enough to identify the problems and solve them.
