Strength is often the most significant parameter in measuring the effect of soil improvement in geotechnical engineering practice. In this paper, a primary study is made of the variation in unconfined compressive strength of lime-treated soft clays under various practical conditions. There are three major factors that affect the strength NotationA w ratio of lime to clay by weight, both in dry state A w,max optimum lime content a rate of strength increment in the logarithmic t scale q shear stress q 0 strength of the untreated soil q max maximum unconfined compression strength q T0 strength at T ¼ 08C T curing temperature t curing time AE Aw material parameter describing the influence of lime content AE T material parameter describing the influence of curing temperature AE t material parameter describing the influence of curing time AE w material parameter describing the incremental rate of increase in strength with lime content

“…The hydrous silica and alumina will then gradually react with the calcium ions to form secondary cementitious products that harden with time (Saitoh et al, 1985). The mechanism controlling the strength development of lime-stabilised silty clay has recently been studied by Horpibulsuk et al (2011).…”

“…all the introduced nano particles plays the most significant role. Furthermore, nano particles accelerate hydration of cement due to its high surface energy [5]. Also, nano materials cause physical alterations such as improvement in the packing density which corresponds to filling effect of its particles [6].…”

Abstract-This study deals with the effect of addition of nanoColin on some properties of the soil compared Properties obtained from tests carried out on samples. characteristics were obtained from tests conducted on normal sandy soil samples with those obtained from tests performed on the same samples after the addition of nano Colin them. Was a standard proctor test record on the sandy soil used samples (replacement) and we got the laboratory maximum dry density value, After that we have implemented a sand cone method for in situ density and compaction of which we got a coefficient before the addition of nano-Cullen and show us that compaction factor ratios ranging from 95.3 to 96.8% of the value of the laboratory maximum dry density. After mixing the material nano Colin sandy soil in a certain way and at rates ranging from 3-4 g / m3 of sand were carried sand Cone method experience of on them for compaction factor become clear to us increase the value of density in situ at a rate ranging from 15-20 percent of what it was before the addition of nano-Cullen . The results of testing the effect of nanoColin on samples that have been. decrease value ratio blanks from 0.62 to 0.56 of the soil blended nano-textured Colin.ankhvd substitution layer thickness used 1.0 m to 0.5 m at a rate of 50% after the addition of nano-Collen. A significant reduction of the value of the economic cost per cubic meter was observed case and found that it reduced by 15%, including the price of the material used and the cost of all tests conducted in the laboratory of soil mechanics and foundations , Faculty of Engineering in QenaSouth Valley University -Egypt and field tests were also within the college of engineering Qena. The results showed the compaction nature of soil get increase compaction factor and stress characteristics with adding nano materials.

“…Quanto aos resultados dos Limites de Atterberg, indicados na Figura 2, verifica-se que: (a) o solo natural apresentou o maior valor do LL (85%), e o acréscimo da cal proporcionou um decréscimo neste parâmetro; (b) houve também uma diminuição do LP à medida que aumentou a participação do resíduo nas misturas, podendose justificar um maior valor deste parâmetro para o solo natural devido ao menor teor de areia encontrado na amostra (Cabral, 2008); (c) analogamente, a respeito do IP, observa-se uma diminuição com acréscimo do resíduo, pode-se associar essa diminuição ao processo de permuta catiônica, onde há a floculação das partículas de argila causada pela adsorção de íons Ca++ (HORPIBULSUK et al, 2011). Em contrapartida, há um aumento do IP com acréscimo de 4% de CC, em relação ao solo com 2% de CC, oriundo de uma diminuição gradual do LP e aumento quase insignificante do LL.…”
