Fluidity
This Chapter refers to fluidity, i.e. the second component of injectability of the grout: The grout should be able to easily flow along the sinuous paths of internal interconnected discontinuities, up to a distance larger than the distance between consecutive grout tubes. To this end, appropriate water-to-solid ratio (W/S), superplasticizer content (SP) and mixing technique should be selected. A new practical (but scientifically significant) fluidity measurement is proposed (the Fluidity Factor Test FFT), and a “fluidity factor” is defined. It is proved that the follow-up of this factor as a function of the water-to-solids ratio may reveal fundamental characteristics of the grout-composition under design. The influence of the mixing method and superplasticizer on grout’s fluidity is also experimentally studied. The chapter concludes with a case study to highlight the practical use of the proposed test.
