The use of rheology in the study of the composition effects on the fresh behaviour of hydraulic lime grouts for injection of masonry walls

Influence of superplasticizer, temperature, resting time and injection pressure on hydraulic lime grout injectability. Correlation analysis between fresh grout parameters and grout injectability

“…Regarding to the grout composition, certain parameters play an important role on the fresh grout behaviour, such as binder type, water/binder ratio (w/b) and SP dosage [19,7,8]. For that reason, it is extremely important to study the different parameters that are involved in grout composition and their influence on fresh state behaviour.…”

“…Through SP action, an improvement of fresh grout parameters is expected by increasing the fluidity, water retention and stability [5]. However, it is well known that fresh grout behaviour of cementitious pastes with SP depends on type and dosage [7]. So this issue will be further detailed, as well as the influence of SP action on hydraulic-lime grout injectability.…”

Evaluation of consolidation of different porous media with hydraulic lime grout injection

“…After various preliminary attempts [14] with different brands and percentages, a polycarboxilate (Glenium SKY 617) produced by BASF was chosen.…”

Evaluation of the grout injectability and types of resistance to grout flow

“…The grout composition was chosen based on the results of some tests, namely: fluidity, water retention, stability and injectability. This study was carried out in another article of the authors [23,24].…”

“…The formulation of the grout was chosen based on the guidelines and recommendations of the several authors [12,[22][23][24] and used a HL5 hydraulic lime (EN459-1) produced in Portugal by Secil-Martingança. The water/binder ratio (w/b) was 50% in weight with 1.2 wt% of superplasticizer (polycarboxilate Glenium SKY 617 produced by BASF).…”
