Abstract The utilization of tail void grout as a stabilizing and sealing agent in mechanized tunneling procedures is paramount significance, given the geological engineering conditions inherent to projects. Prior its application within tunnel, detailed evaluation fresh-state characteristics grout, well time-dependent evolution hydro-mechanical properties, becomes imperative. This review paper a...

a new chemical grouting method has been developed for conglomerate formations based on the experimental studies. due to the lack of chemical grouting experience of conglomerate formations, the testing programs were performed to evaluate the performance of chemical grouting in the water sealing of part of conglomerate foundation of karkheh earth dam using a combination of field and laboratory te...

tunnelling through cities underlain by soft soil, commonly associated with soil movement around the tunnels and subsequent surface settlement. the predication of ground movement during the tunnelling and optimum support pressure could be based on analytical, empirical or the numerical methods. the commonly used earth pressure balance (epb) tunneling machines, uses the excavated soil in a pressu...

One solution to the high cost and scarcity of building materials is use alternative sustainable materials. The study presented herein developed an eco-friendly masonry grout using volumes palm oil clinker powder replace cement coarse aggregate. Several batches grouts with different amounts these were made determine technical viability grout. Scanning Electronic Microscope (SEM), X-Rays Diffract...

Abstract The development and construction of offshore wind farms requires the correct estimation friction that can be mobilised at rock/grout interface. In conventional studies, shear behaviour a joint is usually investigated with laboratory tests under constant normal load/stress (CNL), however, in engineering practice, direct testing stiffness (CNS) has been proved to more realistic assessmen...
