Laboratory Determination of Consistency of Grouting Mixes
Abstract:
Designing of grouting mixes for reinforcement of non-cohesive soils has to satisfy demanding needs. Grouting mix has to have good workability, volumetric stability, good penetration capability, sufficient strength and, last but not least, it should not be too expensive. For above-mentioned reasons, clay-cement suspensions seem to be an appropriate candidate, also because they can be topped up with high-temperature fly ash for even higher cost saving. The paper presents results of preliminary tests of consistency of grouting mixes with various proportions of added fly ash and cement. The tests determined particularly liquid limit and viscosity limit with Marsh funnel.
