Abstract: Soil improvement techniques have been widely used to enhance the engineering properties of weak soils that do not satisfy construction conditions, mainly in terms of bearing capacity. In our case, a weak soil classified as Lean Clay with Sand (AASHTO classification system) was improved adding Lime with different percentages in terms of weight of the dry soil. In order to assess the level of achieved improvement, the various samples, with 2, 4, and 6% added Lime was tested and assessed in comparison to the reference soil, i.e. disturbed with no addition of Lime. The sieve analysis, the Atterberg limit, the chemical analyses, i.e. Sulphate, Chloride contents and PH value, are carried out. The fourth sample with 6% added Lime illustrated the best results. On the one hand, based on the sieve analysis, the original soil classified as A-6, indicating very weak soil, was improved to A-1-b class that represents well-graded sand, which indicates an excellent soil. On the other hand, the more th

Abstract: We studied the effects of using industrial steel solid wastes resulted from lathes to enhance the compressive strength of concrete. In average, 3-4 Kg/lathe of steel waste fibers are produced on daily basis. Such steel waste can be recycled in order to mitigate its environmental hazards. Moreover, using it to reinforce concrete is a feasible and sustainable solution. Six (6) concrete cube specimens were casted with (1% and 2%, in terms of concrete weight) and without steel waste then tested under compression. Also, the workability of the casted fresh concrete with different ratios of steel waste (0%, 1%, and 2%) was estimated utilizing the slump test. The results shows that adding lathes steel waste fibers to plain concrete enhances its compressive strength while the workability of the fresh concrete containing the steel waste fibers decreases.
