  • GRADATION OF AGGREGATE FOR CONCRETE BLOCK

    1. Strength—The influence of aggregate gradation on the compressive strength of finished concrete block will determine the necessary cement content to produce block which meet specified strength requirements. Since cement is the most costly ingredient in the concrete mix, the selection of a properly graded aggregate assumes an economic aspect. 2.Gradation Charts New Enterprise Stone & Lime Co., Inc.,Gradation Charts. The charts below show typical gradations of various products based on required specifications from agencies and organizations such as state DOTs, AASHTO, etc. Anti-Skid . Coarse Aggregates.

Aggregate is classified as two different types, coarse and fine.

  • Metrics and Sieve Sizes, Concrete Construction Magazine

    Jan 01, 2002· Aggregate stone numbers refer to aggregates that meet the grading requirements listed in Table 2 of ASTM C 33, "Standard Specification for Concrete Aggregates." The larger the number, the smaller the size of the stone. Stone number is defined by the amount of an aggregate that will pass through specific sieves by mass percent.TABLE 1005-1 Section 2 AGGREGATE GRADATION COARSE,AGGREGATE GRADATION COARSE AGGREGATE A.

    An optimized gradation based on aggregate availability and project requirements will result in an economical concrete with good workability and finishability. The proportions between coarse and fine aggregates will change based on the unique characteristics of each aggregate, the placement method, and the finish desired.Aggregates Portland Cement Association,Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel.
