原始语种摘要: Grouting generally is used to fill the voids in the ground (fissures and porous structures) with the aim of increasing resistance against deformation, to increase cohesion, shear strength and uniaxial compressive strength or finally (even more frequently) to reduce conductivity and interconnected porosity in an aquifer. In the case of loose sandy soils, the very low bearing capacity of the foundation bed causes shear failure and excessive settlements. Cement grouting technique is one of the possible solutions to the foundation problems for improving the properties of soil at shallow depths. Various authors have recommended a number of additives that can be used in cement grouting. Admixtures like antibleeder increases viscosity of the cement grouts, at the same time reducing sedimentation...
