Expansive clay is one of the most widely distributed soils in world. Due to its rich content strongly hydrophilic minerals—such as montmorillonite—expansive exhibits substantial swelling and shrinkage properties, overconsolidation. The formation process undisturbed expansive has a long complicated geological history innumerable drying–wetting cycles, resulting special internal structures. In th...

Expansive soil swells when it is wet, and will shrink dries. Due to this behavior of the soil, strength other properties are inferior. To improve its properties, necessary stabilize with different stabilizers. Soil stabilization a process treat maintain, alter, or expansive performance. In study, potential 'Fino' as stabilizing additive was investigated for improving engineering be used subgrad...

The mineral calcium sulphate transforms from anhydrite through bassanite to gypsum and then can convert back to bassanite and anhydrite. This transformation of calcium sulphate causes volume change that adds to the potential hazards with indigenous soils containing expansive clay minerals. Heave and settlement are the most important geotechnical problems associated with many argillaceous soils ...

Hadamard (or complete $CAT(0)$) spaces are complete, non-positive curvature, metric spaces. Here, we prove a nonlinear ergodic theorem for continuous non-expansive semigroup in these spaces as well as a strong convergence theorem for the commutative case. Our results extend the standard non-linear ergodic theorems for non-expansive maps on real Hilbert spaces, to non-expansive maps on Ha...

we say that a finite group $g$ is conjugacy expansive if for anynormal subset $s$ and any conjugacy class $c$ of $g$ the normalset $sc$ consists of at least as many conjugacy classes of $g$ as$s$ does. halasi, mar'oti, sidki, bezerra have shown that a groupis conjugacy expansive if and only if it is a direct product ofconjugacy expansive simple or abelian groups.by considering a character analo...

The creep deformation of expansive soil has been considered as a vital threat to the safety in engineering construction because it may cause serious slope diseases geological engineering. Meanwhile, since usually remains unsaturated state, its mechanical property is significantly affected by seasonal environment. Therefore, nonlinear received increasing attention, especially humidity-dependent ...

begin{abstract} in this paper, we introduce an iterative method for amenable semigroup of non expansive mappings and infinite family of non expansive mappings in the frame work of hilbert spaces. we prove the strong convergence of the proposed iterative algorithm to the unique solution of a variational inequality, which is the optimality condition for a minimization problem. the results present...

Expansive soils have high compressibility, swelling, and shrinkage properties. So we need an effective method to improve soil conditions when the structure is built on it. This paper presents results of research effect substitution ceramic waste physical properties expansive soil. Soil improvement using construction will contribute reducing amount conserving natural resources. The stages includ...

Expansive soils swell when they absorb water and shrink when water evaporates from them. Hence, lightly loaded civil engineering structures founded in these soils are subjected to severe distress. Therefore, there is a need to ameliorate or improve these swelling soils through some innovative methods. This paper discusses chemical stabilisation of expansive soils, a technique in which chemical ...
