Ideal and Quasi-Ideal Grading of Coarse and Fine Aggregates …
Abstract. In an earlier publication the author presented a set of tables for proportioning continuously and gap-graded concrete of 38-mm (1.5-in.) maximum size, on the basis of Weymouth's theory of particle interference. In this paper, Weymouth's theory has been restated in algebraic form, thus making applications to mix proportioning less difficult. …
A mathematical model to predict the porosity and …
The test data were analysed to establish mathematical relationships between the three factors and the two characteristics of pervious concrete. The models accurately predicted the porosity and compressive strength based on the aggregate size, aggregate-to-cement ratio and compaction effort.
Gradation and Size – Pavement Interactive
Free online knowledge for the paving industry. The particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material.

A stereological analysis of aggregate grading and size …
Since the weakest link in normal strength concrete is represented by the interface between the cementitious matrix and the aggregates, it seems reasonable to look for a relationship between the aggregate grading and the material strength.

Aggregates for Concrete
3.1.1 Definition and test method—Grading refers to the distribution of particle sizes present in an aggregate. The grading is determined in accordance with ASTM C 136, "Sieve or Screen Analysis of Fine and Coarse Aggregates." A sample of the aggregate is shaken through a series of wire-cloth sieves with square openings, nested one above ...
Use of recycled concrete aggregate in concrete: a review
The use of recycled concrete aggregate (RCA) in concrete as partial and full replacements of natural coarse aggregate is growing interest in the construction industry, as it reduces the demand for aggregate.
