“…In an attempt to provide physical significance to the existing empirical database, Diambra et al (2018) proposed a theoretical model based on the concept of superposition of the failure strength contributions of the sand and cement phases to establish a link between the inherent properties of sandy soil and Portland cement grains and the empirical coefficients of Eq. (4).…”

“…A Figura 12 apresenta a relação direta de q t /q u ,, deste modo a constante-relação se obtém uma forma potencial: q t = 0,0115q u 1,38 (R 2 = 0,97) com excelente coeficiente de determinação. No entanto, todos os dados experimentais de maneira direta apresentam uma relação linear entre q t /q u =0,10 e q t /q u =0,18 como é mostrado na Figura 12. Segundo DIAMBRA et al [44], para solos arenosos cimentados artificialmente, a existência de uma relação entre as resistências à tração/compressão (=q t /q u ) é independente do tempo de cura e está governada, principalmente, pela relação à tração (ou propriedades de fricção) do cimento. Autores como CONSOLI et al [45] calcularam uma relação q t /q u de 0,13 para misturas de solos finos compactos com cimento Portland usando teores de umidade de moldagem de 17, 20 e 23% e pesos específicos secos de moldagem entre 14 e 16 kN/m 3 .…”

“…Basically, the hydration forms cementitious products like calcium silicate hydrates that bind the particles together. Many studies have been conducted on cemented clay investigating the structure [7][8][9], strength [10][11][12][13][14][15][16], compressibility [17][18][19][20], triaxial behaviour [21][22][23] and stiffness [24,25]. However, these studies have focussed on the behaviour of pure cemented clay or sand, although in-situ soil is seldom homogeneous.…”
