Optimisation of flow behaviour and stability of superplasticized fresh hydraulic lime grouts through design of experiments
TLDR
In this paper, the influence of grout mixing procedures on rheological behavior, water retention and stability of hydraulic lime grouts with superplasticizer was analyzed, and it was shown that fresh grout behavior can be improved using an appropriate mixing procedure, optimised with the Taguchi method.About:

An investigation of rheological properties of cement-based grout mixed with rice husk ash (RHA)
Fatih Celik,Hanifi Canakci +1 more
TL;DR: In this article, the fluidity and rheological properties of the cement-based grout mixed with rice husk ash (RHA) were investigated, and it was shown that increasing replacement level for the RHA amount increases marsh cone flow time, plate cohesion, plastic and apparent viscosity, and the yield stress, but also decreases mini slump diameter.

Effect of different superplasticisers on the physical and mechanical properties of cement grouts
TL;DR: In this paper, the effects of polycarboxylate superplasticiser (PCE) on the rheological properties, mechanical strength, final setting time and bleeding of cement grouts in comparison to that of a polynaphthalene super-agent (SNF) were investigated.
Journal ArticleDOI
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.

Comparison of rheological models for jet grout cement mixtures with various stabilizers
TL;DR: In this paper, a thorough comparison of the most common rheological models (Bingham, Modified Bingham, Casson, Herschel-Bulkley, Robertson-Stiff, De Kee) for prediction of flow behavior in terms of the shear stresses due to the cement grout mixtures incorporating with the stabilizers of clay, sand, lime, bottom ash in various proportions (0-100%) has been addressed in this article for jet grouting.

Steady state flow of cement suspensions: A micromechanical state of the art
TL;DR: In this paper, a conceptual diagram of predominant interactions in flowing cementitious suspensions under simple shear, as a function of shear rate and solid fraction, is presented, with the objective to understand and classify the situations where, depending on composition and processing, one or other of the physical phenomena will control the macroscopic behavior.

TL;DR: In this article, the authors propose three categories to describe the interactions and state of the superplasticizers with the cement suspensions, i.e., intercalation, coprecipitation or micellization.
