Effect of coarse aggregate grading on the ASR expansion ...

This study investigates the influence of aggregate grading on the expansion and damage of concrete due to ASR. Three mixes of concrete are compared with the primary variable being the coarse aggregate grading as: a standard composition as per ASTM C1293 ; a fine-dominant composition; and a coarse-dominant composition.

Effect of the aggregate grading on the concrete air ...

This paper discusses the effect of the aggregate grading and water/cement ratio on the air permeability coeffi-cient. An aggregate grading with more sand than coarse aggregates has resulted more beneficial from the point of view of concrete air permeability. This fact can be attributed to a denser skeleton formed by the finer aggre-gates.

Sieve analysis - Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
