scope: This specification covers ready-mixed concrete as defined in 3.2.2 (Note 1). Requirements for quality of ready-mixed concrete shall be either as stated in this specification or as ordered by the purchaser. When the purchaser's requirements, as stated in the order, differ from those in this specification, the purchaser's requirements shall govern.
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. Lightweight aggregates are covered in ASTM C330 (for structural concrete), C331 (for masonry units), and C332 (for insulating concrete).
specification. As part of a recent IPRF study, a proposed specification for concrete airfield pavement has been developed for possible adoption by the FAA. The proposed specification places emphasis on the need to produce a durable end product, that is, a durable concrete pavement. The product requirements that are specified are a combination
3) As ingredients in portland cement concrete Aggregates may also be used as special backfill material, ripr ap, mineral filler, and other less significant uses. COMPACTED AGGREGATES Compacted aggregates without the addition of a cementing material may be used as a base or subbase for hot mix asphalt and portland cement concrete pavements.
Recycled concrete and masonry (RCM) which is graded aggregate produced from sorted and clean waste concrete and masonry typically for road sub-base applications. 3. Reclaimed aggregate which is aggregate reclaimed from concrete returned to a batching plant by separating the aggregates from the water-cement slurry. 4.
Note 1: This specification is regarded as adequate to ensure satisfactory materials for most concrete. It is recognized that, for certain work or in certain regions, it may be either more or less restrictive than needed. For example, where aesthetics are important, more restrictive limits may be considered regarding impurities that would stain the concrete surface.

In fact, for most conventional concretes, more than 75% of the volume is aggregate. Aggregates are essential in concrete from the point of view of economy (since cement is expensive), dimensional stability (aggregates do not easily creep or shrink), stiffness, and abrasion resistance.
Properties of Aggregates. Approximately 75% of the volume of concrete is occupied by aggregates, so quality of aggregates plays an important role in determining properties of concrete. Aggregates are chemically inert, solid bodies held together by the cement.
Review precast concrete specification requirements and note any special requirements including specified exceptions to those of general concrete.

Dry mix concrete plant is special and is different from traditional concrete batching plant. Compared with traditional concrete mixing plant, dry batch concrete plant has no concrete mixer. Instead, it uses concrete truck to mix concrete. When aggregates are weighed by batching machine, they will be put into concrete truck.
