Physical and geotechnical properties of clay phyllites

Characteristics and ceramic properties of clayey materials from Amezmiz region (Western High Atlas, Morocco)

“…Illite and quartz were the major minerals followed by vermiculite. Illite favors the sintering step permitting the formation of a liquid phase at a lower temperature and thus contributes to the increase of the density (Garzón et al, 2010). Quartz facilitated the drying step (diminishing of the drying shrinkage and of the risk of crack formation); the relatively high amount of quartz which represents more than 51 wt.% in all the samples of Amezmiz explains the absence of defects due to drying in the unfired ceramic body.…”

Physicochemical Characterization of Pulverized Phyllite Rock for Geopolymer Resin Synthesis

“…It is known that phyllite is a material of great geological abundance in Brazil, of low cost and is already commonly applied in the ceramic industries as a partial substitute of kaolin. In addition to mortars, it is also used in: sanitary stoneware, animal feed, pigment and binder, special concretes, and waterproof materials, due to its low permeability 7,8 . This paper presents the physical and microstructural characterization of two phyllite varieties and their calcined products used as geopolymer resin precursors in order to evaluate their potential for kaolin replacement.…”

Phyllite clay–cement composites having improved engineering properties and material applications

“…Referring to Fig. 3, MP compactive effort produced quite high maximum dry densities, which were greater than that of the in-situ phyllite clay material (2.03 Mg/m 3 , Garzón et al (2010)). The MP maximum dry density reduced slightly, and approximately linearly, with increasing cement content; from 2.25 Mg/m 3 for the phyllite clay to 2.14 Mg/m 3 for the composite with 9 wt.% cement.…”

“…In its natural state, the phyllite clay material had a very low gravimetric water content ranging of 1-2% (mean of 1.8%), a void ratio (volume of voids to volume of solids) of~0.39, and a dry density of 2.03 Mg/m 3 (Garzón et al, 2010). The sampled phyllite clay material was oven dried at 105-110°C to constant mass, allowed cooling to ambient laboratory temperature, disaggregated and then dry sieved to obtain the fraction passing b125 μm.…”
