In each plot, three samples for soil apparent density were cored with a cylinder then dried and weighed.
The constituents and procedure used to produce rigid PU foams containing polyols derived from recyclable resources have been described in detail in [19] for the specific case of foams of 200 kg/[m.sup.3] apparent density. Below, we briefly recapitulate the formulation of the foams and the method used for obtaining foams of different densities.

The pellets, also known as green ceramic pellets, must have at least 50% of relative apparent density in order to attain final densities in the sintered ceramics that are high enough to be useful (usually higher than 90%).
Apparent density [[rho].sub.A] was determined by water displacement method as reported in Dutta et al.
The determination of the apparent density of the aerogels obtained by freeze-drying and cellulose (as received) was performed by an adaptation of ASTM D3575-14 standards, by measuring the volume and the mass of the obtained aerogels, according to (1).
The aim of this work is to record the combined effect of some significant synthesis parameters such as the Si foaming agent content (% w/w fly ash based), the alkali type (R : Na or K), and the alkalinity (R/Al molar ratio) of the activation solution on the compressive strength, the apparent density, and the porosity development of the foamed fly ash-based geopolymers.
Apparent density was also measured for the same pastes tested in three-point bending; results are presented in Figure 10.
