EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON CONCRETE .

+

increase in aggregate size results in a decrease in the compressive strength of concrete. Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi), smaller sized coarse aggregate produces higher strengths for a given watertocement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used to make highstrength concrete, it is easier ...

P i = 100 (d i /D), where P i = % passing sieve size d i, and D = maximum size of aggregate. In the 1960s, the Federal Highway Administration (FHWA) came up with the ' power' gradation chart for aggregates in concrete mix design. This was designed to give straight lines for maximum density gradations. Modern advances in mix design methods have built upon the necessity of maximum ...

The grain sizes were confined to the range from mm to mm. The fine aggregate comprised barite powder only and was made from barite ore by grinding. The fineness was consistent with a material retained between the 300 to 400 meshes. Highquality natural resin, dissolved in 95% medical alcohol, was used as the blender in this preparation process.

The grading or size distribution of aggregate is an important characteristic because it determines the paste requirement for workable concrete. This paste requirement is the factor controlling the cost, since cement is the most expensive component. It is therefore desirable to minimize the amount of paste consistent with the production of concrete that can be handled, compacted, .
