“…aims to improve some properties. Since then, several research efforts have been made towards documenting environmentally friendly materials with an emphasis on improving the properties of cement suspensions such as bleeding and durability [1][2][3][4][5][6][7][8]. Soil is one of the most important and at the same time most complex factors affecting the injectability of cement-based suspensions.…”

The improvement of the mechanical properties of soils can be attained by the execution of an appropriate injection program. The injection materials that are used for that purpose, called grouts, may be either suspensions of solid particles in water or chemical solutions. Cement suspensions penetrate satisfyingly into coarse sands, whereas chemical solutions penetrate satisfyingly into finer formations, such as fine sands or silty soils. Over the last years, efforts have been made for the evolution of microfine cements suspensions, in order to replace the chemical solutions, which are thought to be toxic and harmful for the environment and the human. In this work, the effect of soil parameters such as uniformity coefficient and degree of saturation on the injectability of cement suspensions is evaluated.

“…In general, the age of 28 days is considered as a common reference point among researchers for the long-term durability of a suspension. To improve cement grout strength, research efforts in recent years have focused on the use of special cements composed of very fine particles, like fine and ultrafine cements [8][9][10][11][12][13][14].…”

Grouting is a common technical method with many applications, e.g., it is used for soil stabilization and strengthening, for reduction for water ingress to underground facilities or of the water loss through a dam foundation, etc. Grouts comprise several constituents, which are combined in many ways depending on the in-situ conditions and the outcome desired. The use of very fine cement grouts for injections into fine-to-medium sands has been proposed to circumvent problems associated with the permanence and toxicity of chemical grouts and the inability of ordinary cement grouts to permeate soil formations finer than coarse sand. The strength of a suspension is the property of probably most interest in cases where the main objective of a soak injection program is to improve the mechanical properties of the soil. The object of this paper is to investigate the effect of cement physical properties, water-to-cement ratio, additives and chemical improvers on the strength of cement suspensions.

“…As a result, a number of fine-grained cements, called microfine or ultrafine cements, has been developed and manufactured. The behavior of microfine cements in permeation grouting is the objective of many research efforts [9,10,11,12,13,14,15].…”

The use of very fine cement grouts for injection into fine-to-medium sands has been proposed to circumvent problems associated with the permanence and toxicity of chemical grouts and the inability of ordinary cement grouts to permeate soil formations finer than coarse sand. A laboratory investigation was conducted in order to evaluate the penetrability of cement suspensions. Four gradations from CEM I (according to EN 197-1) type of cement were used having nominal maximum grain sizes of 100 μm, 40 μm, 20 μm and 10 μm. The properties of suspensions, with water-to-cement (W/C) ratios of 1:1, 2:1 and 3:1 by weight, were determined in terms of apparent viscosity. Penetrability was evaluated by conducting one-dimensional injections into five different, clean sands using a specially constructed device. Penetrability of cement suspensions increases with increasing water-to-cement (W/C) ratio and cement fineness. Microfine cement suspensions with water-to-cement (W/C) ratios of 2:1 and 3:1 can penetrate into medium-to-fine sands.
