A new fully integrated ultrasound based in-line fluid characterization system, FlowViz, has been developed especially for opaque, non-Newtonian industrial fluids. The new embedded and commercially available system is designed to meet industrial requirements. Flow-Viz enables true non-invasive, real-time Doppler measurements and is able to visualize the flow and to rheologically characterize ind...

To reveal the strengthening mechanism and re-failure of grouting on fractured rock, variable-angle shear tests, real-time acoustic emission (AE) tests VIC-3D (non-contact full field strain measurement system) were carried out intact red sandstone (IRS) grouting-reinforced body (GRBFRS). The results show that peak strength IRS GRBFRS decreases with increase angle. Grouting reinforcement mainly i...

Dalam pembangunan bendungan urugan kekuatan pondasi sangat penting. Pondasi harus dipastikan memiliki daya dukung yang kuat, maka dilakukan perbaikan dengan cara grouting. Terdapat dua metode saat pekerjaan grouting yaitu downstage dan upstage. Tujuan penelitian ini untuk mengetahui mana memberikan keuntungan lebih banyak. Metode upstage biaya sebesar Rp2.704.279.000 waktu selama 2350 menit, se...

Post-grouting technology has been extensively used in geotechnical engineering to improve the bearing capacity of various piles, which overcomes technical limitations bored piles and recovers mechanical performance strata. A considerable amount earlier research conducted investigate behavior reinforcement mechanism grouted while very few studies focus on area post-grouting technique. The theore...

Abstract Grouting reinforcement is an effective method for controlling fractured rock in the deeply buried roadways of coal mines. However, quantitatively evaluating strength grouted masses remains a challenge. The design grouting primarily based on empirical knowledge. Consequently, this study proposes real-time in-situ quality using measure while drilling (MWD) roofbolter. Initially, we valid...
