Apr 26, 2018 CDS elevates energy efficiency with steam-based aggregate drying method April 26, 2018 Concrete News Best known in manufactured-concrete production for its Envirocure technology, CDS has unveiled the R-O2 Drying System, whose reduced oxygen, superheated steam atmosphere serves as an energy-wise medium for bringing sand, gravel and stone.
In normal concrete the aggregate weighs 1,520 – 1,680 kg m 3, but occasionally designs require either lightweight or heavyweight concrete. Lightweight concrete contains aggregate that is natural or synthetic which weighs less than 1,100 kg m 3 and heavyweight concrete contains aggregates that are natural or synthetic which weigh than.

Abstract This invention relates to an improved aggregate drying apparatus and method where the dried aggregate is particularly useful for making hot mix asphalt. In accordance with the system, heat typically lost in exhaust gases and moisture evaporated in a heater is recovered to dry and preheat the aggregate.
Essentials of Process Design for Aggregate Crushing Plant. Designed from the perspectives of the stability of production and operation (dry method, wet method and combination of dry and wet), product quality stability (selection of auxiliary equipment such as crushing, screening, sand making equipment, conveying equipment), investment cost.

Aug 23, 2007 The tricky part is that the mix design typically is based on dry aggregate, so any water in the aggregate has to be subtracted from the water to be used in batching the concrete. The concrete producer may adjust the mix design to account for typical aggregate moisture conditions, such as saturated-surface-dry (SSD), but must either continually.
