Effects of Aggregate Grading on Drying Shrinkage of ...Concrete specifications for slabsonground often require the use of a 11/2 in. (38 mm) nominalmaximumsize aggregate plus a combined aggregate grading (both coarse and fine) that meets the "818 rule." This rule requires 8 to 18% of the combined aggregate to be retained on each standard sieve below the top size and above the No. 100 sieve.
Development of Concrete Mixtures Equipment ContractingThe concrete mixture can be enhanced by optimizing the grading with the combined aggregates. Generally, the aggregates are dimensionally and chemically stable, which is why it is preferred to maximize aggregate content and minimize the cement paste that has higher chemical reactivity.
