Enhance the Engineering Properties of Low Load Carrying Capacity of Expansive Soil by Using Alccofine-1203 and Phosphogypsum
Extensive soil originates in dry and semi-arid parts of the globe. One of the issues associated with such expansive soils is their tendency to inflate in accordance with an upsurge in their natural moisture content. Numerous issues with substructure, including houses, roadways, breast walls, etc., are imposed by the various swell-shrink performance of soils. Civil engineers have put forth a lot of effort to comprehend the performance of clay soil and apply proper control techniques. The aim of study is to determine the effectiveness of alccofine-1203 (3, 6, 9, and 12%) and phosphogypsum (PG) (0.25, 0.5, 0.75, and 1.0%), enhancing the engineering characteristics of soil, such as swelling behaviour and low load-carrying capacity, which includes the benefits of civil engineers. The experiments are LL, PL, SL, PI, optimum moisture content (OMC), unconfined compressive strength (UCS), maximum dry density (MDD), SEM, XRD, along with other important soil characteristics that were calculated using an experimental program. These additives were applied separately and merged into the soil. The results reveal that the LL, PI, optimal moisture level, and swelling behaviour of soil significantly declined with the accumulation of additives. With the combined effect of 12% alccofine + 1.0% phosphogypsum of expansive soil, UCS improved from 46.4 to 155 kPa. The strength improved owing to the growth of calcium silicate hydrate (C–S–H), calcium aluminate hydrates (C–A–H), and other cementitious complexes observed in SEM and XRD studies. As a consequence of results, it has been observed that the accumulation of 12% alccofine + 1% phosphogypsum acted as a valuable additive on the highly expansive soil, and that through the inclusion of additive, an undesirable soil was transformed into a superior.
