The function of this paper is to provide both a library research and a laboratory testing program that will help explain the determination of capillarity and pore size interrelationships and their effect on durability of porous materials. Most porosity measurements provide results that are dependant on the test method employed. Porosity can be measured using specific gravity methods

Sieve Analysis. Gradation of aggregates is determined from sieve analysis, in which a representative sample of aggregate is passed through a series of sieves and the weight retained in each sieve expressed as a percentage of the sample weight is compared with the grading limits specified.

Porosity or void fraction is a measure of the void (i.e. empty) spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and . Strictly speaking, some tests measure the accessible void, the total amount of void space accessible from the surface (cf. closed-cell foam). There are many ways to test porosity in a
