Concepts of specifications for ready mixed concrete addressed in industry standards published by ACI or ASTM International. Provisions of ACIBuilding Code for Structural Concrete, as it relates to requirements concrete ingredient materials and mixtures, production and delivery are incorporated.

This standard is issued under the fixed designation C 94/C 94M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the. This specification covers ready-mixed concrete as defined in (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. {Answer} A big change occurred in ASTM C94, the standard specification for ready-mix concrete found in almost all commercial specifications.

That change requires the purchaser to inform the producer of the specification. It seems obvious to me that this should be a normal part of the course of business.

The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like.
