Experimental Study on the Influence of Alccofine-1203 and Phosphogypsum on the Strength Characteristics of Expansive Soil

Expansive soil is generally found in arid and semi-arid regions of the world. One main issues with these expansive soils their swelling properties when natural water content increases. The various swell-shrink tendencies cause numerous substructure distress infrastructures such as buildings, pavements, breast walls, among others. Geotechnical engineers have worked hard to understand behavior expanding implement appropriate management strategies. current study aims elucidate efficacy alcofine-1203 Phosphogypsum (PG) powder achieving geotechnical improving its high swell, shrink, low bearing capacity, which benefits for civil engineering. combination two materials can be more beneficial used a stabilizing agent than using them individually. An experimental programme has calculated effects (3, 6, 9, 12%) (0.25, 0.5, 0.75, 1.0%) on Atterberg limits, optimum moisture (OMC), unconfined compressive strength (UCS), maximum dry density (MDD), other essential characteristics. Both admixtures were added independently blended into soil. It was that liquid limit, plasticity index, content, been greatly reduced addition specified admixtures. UCS gradually increases from 46.4 kPa 948 after 56 days due combined effect 12% alccofine 1.0% reacting soil, plays critical role compared remaining admixture combination. Hence, result concluded PG exhibited an improver soils, proved adding potential stabilizer, also problematic transformed best construction cost by making use locally available materials.
