A series of geopolymer materials was synthesized using class F fly ash (according to the standard ASTMC618-12 a) from a power plant in Poland, designated as fly ash K. The chemical composition of the fly ashes used for the experiment was determined by the XRF method with the use of a Philips spectrometer PW 1404.

In this study, the thermal behavior of perlite concrete used in the SFR was investigated from room temperature to 1886 K. Thermal decomposition was examined by TA, including TG–DTA and TA coupled to evolved gas analysis, and complementary techniques including microscopic observations and X-ray diffractometry (XRD).

1. Introduction. Expanded perlite is a highly porous powder produced from raw perlite, which is an amorphous aluminosilicate of volcanic origin whose main chemical constituents are SiO 2 (around 70%), Al 2 O 3 (around 13.5%), other metal oxides and chemically bound water [1].Raw perlite, which consists of massive particles, is expanded …

Professional growers buy perlite wholesale in larger bags, but these can be a bit bulky for the consumer. A bag that is 2 cubic feet weighs about 8 to 16 pounds when dry. The 4 cubic feet size is more manageable in this case than with vermiculite. The difference in weight comes from the fact that perlite is airier than vermiculite.

Product description. ABTEC Perlite is prepared from a pH-neutral, sterile, safe-to-handle volcanic mineral. ABTEC Perlite is prepared for gardening use by super-heating this mineral until it expands to more than ten times its original volume. The expanded perlite is full of tiny air bubbles, and its dimpled surface area helps trap moisture.

We describe a novel process for expanding perlite rocks, at temperatures from 1220 to 1370 K and elevated pressures, (3.3–16.0) × 105 Pa, in flowing water vapor. Our results demonstrate for the first time that heating markedly increases the compressive strength of perlite, reducing its viscosity and giving rise to perlite expansion in the central part of …

Like perlite, vermiculite is an effective soil conditioner that can loosen compacted soil, provide drainage, and hold three to four times its weight in water. But—and this is an important but —vermiculite is more compressible and less porous than perlite, giving vermiculite higher water-holding capacity when it's used as a planting medium.

I think I'm going to go with vermiculite for a couple reasons: 1- I won't have to water often because the vermiculite will provide moisture unless it's a prolonged dry period; I don't grow cacti, succulents or rhododendrons, and lettuce really doesn't like to dry out; the only perlite available locally has some Miracle Gro in it which I would ...
