Variations in the rheology and penetrability of cement-based grouts—an experimental study
TLDR
In this article, a number of measurements of grout properties relating to the rheology and penetrability of fresh cement-based grout are presented, and the main purpose of this study is to investigate and describe variations that can be detected when measurements of these grout parameters are carried out repeatedly.About:

Experimental study on performance of cement-based grouts admixed with fly ash, bentonite, superplasticizer and water glass
TL;DR: In this paper, the ASTM Type I Portland cement (PC), class F fly ash (FA), bentonite (B), superplasticizer (SP) and water glass were designed to improve properties of grouting materials in different aspects.

Combined effect of superplasticizer, silica fume and temperature in the performance of natural hydraulic lime grouts
TL;DR: In this paper, the effect of environmental temperature over superplasticized hydraulic lime-based grouts with partial replacement of lime by silica fume was analyzed in fresh and hardened state by testing its rheological behaviour, injectability and hydration reactions kinetics.

TL;DR: In this article, three different cements (CEM I, CEM II/B-M and CEM IV/B according to EN 197-1) containing 0, 23.5% and 38% of pozzolan, respectively, were pulverized to obtain three additional gradations from each cement, with nominal maximum grain sizes of 40, 20 and 10μm.

On the viscous behavior of cement mixtures with clay, sand, lime and bottom ash for jet grouting
TL;DR: In this article, the effect of stabilizer versus dosage rates on native cement was determined using the statistical significance analysis of multiple comparisons (Dunnett test) and was found that the employed stabilizers relatively have the potential of contributions to flow capability of the mixtures primarily dependent upon their dosage rates.

Interaction between cement and chemical admixture from the point of cement hydration, absorption behaviour of admixture, and paste rheology
Shunsuke Hanehara,Kazuo Yamada +1 more
TL;DR: In this article, the interaction between cement and the chemical admixture types lignin sulfonate, naphthalene sulfonsate, melamine sulfonates, amino sulfonatate, and polycarboxylate, together with the working factors and mechanisms, are discussed from the viewpoint of cement hydration.

Numerical calculations for prediction of grout spread with account for filtration and varying aperture
TL;DR: In this article, the authors used grouting as a mean to reduce the ingress of water to underground facilities, with an increased demand for tightness and cost efficiency, the incentive to improve the metho...

Influence of mix proportions on rheology of cement grouts containing limestone powder
TL;DR: In this article, a two-level fractional factorial statistical model was used to model the influence of key parameters on properties affecting the fluidity, the rheology and compressive strength.

Computer-simulated flow of grouts in jointed rock
TL;DR: In this article, a model for simulating grout propagation in jointed rock is presented, where the joint planes are described as channel networks initially filled with water and the grouth can be either a Bingham or a Newtonian fluid, with time-dependent properties.
