crushed concrete as coarse aggregate, and perhaps fine aggregate, in the 3000 psi (21 MPa) concrete specified for a project we’re building. Does aggregate produced by crushing returned concrete meet the requirements for aggregates in building codes and commonly used specifications? A. Section 3.3.1 of ACI 318-08, “Building Code Require-

Volume of dry-rodded coarse aggregate per unit volume of concrete for different coarse aggregates and fineness moduli of fine aggregates ACI Mix Design 8. Estimation of fine aggregate content-- There are two standard methods to establish the fine aggregate content, the mass method and the volume method. We will use the "volume" method.
The American Concrete Institute (ACI) has released the 2018 ACI Collection of Concrete Codes, Specifications, and Practices to provide a comprehensive a source of information on concrete design, construction, and materials, with nearly 50 codes and specifications and over 200 practices. The solution, formerly known as the Manual of Concrete Practice, also includes all guides and reports.

meeting a particular specification should be based upon specific information obtained from tests used to measure the aggregate’s quality or, more importantly, its service record, or both. More performance tests are also used to test aggregates in concrete. A typical consensus specification for fine and coarse aggregate for concrete is ASTM C 33.
ACI method of concrete mix design is based on the estimated weight of the concrete per unit volume. This method takes into consideration the requirements for consistency, workability, strength and durability. This article presents ACI method of concrete mix design.
