Question_30_Table_A_Concrete_Mix_Types.pdf

The document is a specification table for Concrete Mix Type C5, detailing the technical requirements for a specific concrete mix design. The table provides comprehensive specifications for a concrete mix, including minimum 28-day compressive strength of 3000 psi, minimum quantity of cementitious material at 470 lbs/cu yd, and minimum Portland cement quantity of 235 lbs/cu yd. The maximum water-cementitious ratio is set at 0.5, and the mix includes Ground Granulated Blast Furnace Slag (Slag Cement) as the "Other" additive. The slump range is specified as 7-9 inches, with no specified air content range.

The specification sheet does not provide additional context about the project, funding, or procurement process. The table appears to be a technical specification extract, likely part of a larger construction or engineering document, focusing solely on the precise requirements for the C5 concrete mix type. The detailed parameters suggest this is a technical specification for a specific construction project or standard, with precise requirements for concrete composition and performance characteristics.
