Phyllite clay–cement composites having improved engineering properties and material applications
Abstract Phyllite clays contain clay minerals (chlorite, illite and mixed-layer illite smectite), quartz and feldspars. In this experimental laboratory study, new composites of phyllite clay and cement (5, 7 and 9wt.%) were prepared and tested to determine their Atterberg limits, dry density and optimum water content for modified Proctor (MP) compaction, California Bearing ratio, swelling potential after soakage in water, unconfined compressive strength (UCS) and water-permeability coefficient. From the mixes investigated, the composite with 5wt.% cement was deemed most suitable for certain construction material applications, having a plasticity index of 10.5%, maximum dry density of 2.17Mg/m3 and optimum water content of 8% for MP compaction (undergoing no swelling under soakage), a UCS of 0.74MPa, and a very low permeability coefficient value of 7.4×10−11 m/s. Potential material applications for these new composites include for building construction, roofs, and flexible pavements.
Highlights First report on stabilization of clay phyllites using cement Effect of 5–9wt.% cement on engineering properties of clay phyllites Most suitable stabilization achieved for phyllite clay with 5wt.% cement
