Laboratory assessment of erosion resistance of underground grout element
Original language description
Erosion of underground grout element resulting from the physical-mechanical effect of groundwater is a crucial problem, therefore the erosion resistance of grout element should be addressed in more detail. This paper aims to experimentally define the erosion resistance of underground grout element subjected to water flow-induced hydraulic forces. Laboratory tests were performed to investigate the resistance of geo-gomposites that practically form the grout element when applying the jet grouting technology. Erosion resistance of the geo-composite is investigated for (1) different composition of the grout suspension and (2) different concentration of the grout suspension within the geo-composite. The specimen of geo-composite was subjected to shear stress resulting from water flow for a certain period. The erosion resistance of the geo-composite specimens is defined depending on the so-called erosion rate which is the weight loss as a percentage of the original weight of the specimen. Final discussion on the experiments and their results is presented.
