aggregate concrete equivalent

  • ITEM 421 PORTLAND CEMENT CONCRETE 421.2. Materials.

    Fine aggregate will be subjected to the Sand Equivalent Test (Test Method Tex-203-F). The sand equivalent shall not be less than 80 unless otherwise shown on the plans. For all classes of concrete, except class K, the fineness modulus shall be between 2.30 .

  • Alkali Content of Concrete Mix Water and Aggregates

    a particular concrete mix, the alkali equivalent of each constituent is first converted to alkali weight in kilograms by plying the alkali equivalent by the weight of the constituent per cubic meter of concrete. The alkali weights of all constituents are then added together to give the total alkali content. Appendix C of CCANZ TR3 (2nd edition)

  • Aggregate Testing Equipment - Gilson Co.

    Aggregate Angularity & Elongation equipment determines the shape characteristics fine and coarse aggregates to evaluate their suitability for asphalt and concrete mixtures. Calipers quickly determine percentages of flat and elongated particles in coarse aggregate fractions of 3/8in (9.5mm) or larger.

  • Permissible Levels of Chlorides and Sulfates in Aggregate ...

    Q. We're designing a concrete structure in Egypt, and I received test results for the aggregate to be used in the concrete. The report lists chloride and sulfate content, but I don't know how to evaluate these numbers because ASTM C 33, "Standard Specification for Concrete Aggregates.
