Building Materials
A grain that satisfies the following conditions (d
being the smallest dimension and D the largest):
the retained material on the sieve of mesh D
lies between
AGGREGATE POROSITY
Porosité d’un granulat
Building Materials
The ratio of the volume of void space within
grains to the absolute volume of these grains.
Porosity is determined by measuring the quantity
of water absorbed by a sample before drying
until constant weight is attained. The sample is
then subjected to a vacuum saturation; this
quantity of water is the absolute volume of the
dry sample.
