Abstract

Construction sector suffer from many problems due to presence of the soft soil in many worlds' parts and to solve these problem the soft soil should be stabilised by either mechanically or chemically; the mechanical ways can be achieved by replacing with stronger materials or using special machines to increase the soil stability result which considered high cost, researchers try to find another method with alternative materials like cement, lime and pozzolanic materials to qualify the soft soil on the civil engineering project. The aim of this study is to evaluate the soft soil properties that cured with 9% binders of various mixtures of binary blended produced from Ordinary Portland cement (OPC) and Fluid catalytic cracking catalyst residue (FC3R), which is a by-produced material from petroleum sector. Geotechnical tests like (compaction, un-confined compressive strength (UCS) test and Scanning electron microscopy (SEM)) were used to investigate the optimum binary mixture. Results show that the use of FC3R as a cement replacement developed the strength of soft soil after 28 days result in a higher strength comparison to using OPC alone in soil stabilisation. SEM proved presence of OPC hydration products during different curing ages. © IAEME Publication.
